JP4622539B2 - WEB content synchronization system and terminal - Google Patents

Description

The present invention, the present invention relates to a WEB content synchronization system and end late to synchronize collaborative browsing to manipulate and display the WEB content using a WEB browser.

  In recent years, various information can be obtained by the spread of the Internet technology using the WWW (World Wide Web) system.

  These pieces of information are called WEB contents and are typified by documents described in a description language called HTML (Hyper Text Markup Language), and can be obtained and used by a program called a WEB browser.

  In addition to the acquisition of information, various web services such as electronic commerce have been developed due to the convenience of Internet technology.

  However, as WEB services diversify, the contents and operation methods of WEB contents have become bloated and complicated, and it has become increasingly difficult to understand.

  For this reason, in order to support the user of the WEB service, there is a technique for sharing the same WEB content by using a general WEB browser such as Microsoft Internet Explorer (registered trademark) and synchronizing operations.

  For example, Patent Document 1 proposes a technique in which a collaboration server operating as a proxy adds a tag for reading a dynamic change detection script and a communication applet for each WEB content.

  Here, the WEB browser can detect a change in state caused by an operation on the WEB content called dynamic change or internal processing by the following two methods.

  In the first method, after a WEB content button or link element is read into a WEB browser, an embedding process of a dynamic change detection script is performed so as to operate by detecting an event such as onclick of each element. The embedding process is a process of setting an event handler function to an event such as onclick using a DHTML (Dynamic HTML) technique. Also, the timing at which the embedding process operates is after the page transition is completed because the buttons and link elements included in the WEB content are not determined unless the page transition is completed, that is, the elements to be embedded are not determined. .

  In the second method, the dynamic change detection script periodically monitors the dynamic change of the web content from the time when the dynamic change detection script is read.

Here, the dynamic change detection script detects the dynamic change and transmits the synchronization information to the collaboration server through the communication applet, and the collaboration server transfers the synchronization information to another user terminal.

  However, the conventional example described above has the following problems.

  The first problem is that there is no exclusivity of simultaneous operations, and when a plurality of users perform operations at the same time, the WEB content transitions to a different page, or the display content of the WEB content becomes different. This means that the synchronization state is shifted. This is because in the conventional method of detecting a dynamic change and transmitting / executing it to other users, the order in which the operations occur is switched when operated by a plurality of users at the same time.

  An example of this problem is shown in FIG. According to this example, when the user 1 operates a button or link on the WEB browser, the display of the WEB browser transitions to page A (step S101), and at the same time, the user 2 also selects the button or link on the WEB browser. When the display transitions to page B by operation (step S111), each WEB browser detects the page transition (steps S102 and S112), and sends page transition synchronization information to each other (steps S103 and S113). (Steps S104 and S114), the WEB browser of the user 1 changes to page B (step S105), and the WEB browser of the user 2 changes to page A (step S115).

  The second problem is that there is a timing at which operations of WEB contents are not necessarily synchronized. In the method in which the dynamic change detection script periodically checks the dynamic change of the WEB content, there is a period that is not synchronized, and the problem is obvious. Also, in the method of embedding the dynamic change detection script, since the dynamic change detection script is embedded when the page transition is completed, the dynamic change of the WEB content can only be detected after this, so synchronization is not performed. Timing exists.

  An example of the problem of the method of embedding the dynamic change detection script is shown in FIG. According to this example, after the page transition is completed, the process of embedding a part that detects a dynamic change is performed (steps S201 to S202). Therefore, an operation is performed during page transition where the embedding process has not yet been performed (step S203). ) Cannot be detected and cannot be synchronized.

Accordingly, the present invention allows a simultaneous operation, i.e. be subjected to a plurality of users have different simultaneous operations, operations on all users occurs in the same order, to provide a WEB content synchronization system and the end-terminal With the goal. Another object is to provide a WEB content synchronization system and end the end there is no timing not synchronize the operation.

On the other hand, if all users have not completed the embedding process, it further comprises child frame operation prohibiting means for prohibiting the operation of the child frame.

According to WEB content synchronization system and ends at the end of the present invention, even when subjected to simultaneous operations on WEB content shared by a plurality of users, shared without synchronization shifts can continue.

  Next, a first embodiment of the present invention will be described in detail with reference to FIG. 1, FIG. 2, and FIG.

  FIG. 1 is an overall view of a WEB content synchronization system for carrying out the present invention. Referring to FIG. 1, the WEB content synchronization system includes a plurality of WEB browsers 1, a shared server 2 that is a communication relay path for WEB content and a sharing command, and a WEB server 3 that stores the WEB content. The processing by the operation on the WEB content displayed in 1 is synchronized with each other, and operates to share the WEB content. However, the number of WEB browsers 1 in the present system is not limited to two, and the present invention can be applied to share WEB content by two or more WEB browsers 1.

  Referring to FIG. 2, the shared server 2 relays the WEB content acquired from the WEB server 3 and transmits it to the WEB browser 1, and also relays the HTTP (Hyper Text Transfer Protocol) request from the WEB browser 1. 3 is transferred to the WEB browser 1 of all users including the transmission source, and is transmitted even if the sharing command is continuously transmitted. And a shared instruction transfer unit 22 for sequentially transferring in accordance with the order. The WEB content relay unit 21 and the shared command transfer unit 22 can be physically disposed separately, and each can independently handle communication of WEB content and communication of a shared command.

  The sharing command transfer unit 22 includes a receiving unit 221 that receives a sharing command transmitted from the communication unit 101 of the WEB browser 1, a temporary storage unit 222 that temporarily stores the received sharing command, and a stored sharing command. And a transfer unit 223 for taking out the data in the order received and transferring it to the communication unit 101 of the WEB browser 1 of all users.

  The WEB browser 1 includes a WEB content control unit 11 that controls the WEB content in order to share the WEB content with other users, a WEB content display unit 12 that displays the WEB content relayed from the WEB content relay unit 21, and Is provided. The WEB browser 1 is a general WEB browser such as Microsoft Internet Explorer (registered trademark), and uses, for example, a structure called a frame capable of displaying a plurality of WEB contents by dividing a display area in one window. The WEB content control unit 11 and the WEB content display unit 12 can be configured by the above, and the WEB content control unit 11 and the WEB content display unit 12 can be displayed using two windows, respectively. .

  The WEB content display unit 12 displays WEB content such as HTML to be shared, embedded processing is performed by the WEB content control unit 11, and the dynamic change detection unit 13 is embedded. If the WEB content has a frame structure, an embedding process is performed for each frame.

  FIG. 3 shows details of the WEB browser in the present embodiment. According to FIG. 2, the WEB browser includes a WEB content control unit 11 and a WEB content display unit 12, and displays the WEB content to be shared on the WEB content display unit 12, and the WEB content control unit 11 controls the plurality of web contents. Sharing among users.

  The WEB content control unit 11 includes a communication unit 101 that transmits and receives a shared command, a shared command control unit 102 that exchanges a shared command with the communication unit 101, analyzes and generates the shared command, and an operation prohibited state of the WEB content. The operation prohibition control unit 103 that controls the web content, the execution control unit 104 that controls the execution of the processing for the operation on the web content, and the embedding unit 105 that performs the embedding processing on the web content.

  The shared command control unit 102 includes a shared command determination unit 1021 that determines the content of the shared command, and a shared command issue unit 1022 that generates and issues a shared command to the communication unit 101.

  An operation prohibition control unit 103 receives an embedding completion notification sent when embedding processing has been completed in all shared WEB browsers, and an operation prohibition canceling unit 1031 that cancels the operation prohibition of the WEB content. The embedded state storage unit 1032 that records the completion status of the embedding process in the web content of a plurality of web browsers, and the data of the embedded state storage unit 1032 that operates when a page transition is detected and prohibits user operation of the web content And an operation prohibition unit 1033 for changing the state to the incomplete embedding state.

  The execution control unit 104 includes an operation classification determination unit 1041, an execution suppression unit 1042, and an operation execution unit 1043. The operation classification discriminating unit 1041 operates when a dynamic change in WEB content is detected, inquires the operation execution unit 1043 whether the internal processing is performed by a shared command, and terminates as it is if the internal processing is performed by a shared command. If it is a process by the user's operation, the execution suppression unit 1042 is called to suppress the process, and the shared command issue unit 1022 is called to issue a shared command as operation information. The execution suppression unit 1042 is called from the operation classification determination unit 1041 and suppresses execution of processing for an operation on WEB content. The operation execution unit 1043 operates when receiving a sharing command that is operation information, and executes internal processing corresponding to the operation of the web content. Note that the operation execution unit 1043 searches the embedded state storage unit 1032 when performing internal processing, and even if one piece of data is in an embedded state, that is, the WEB content is in a page transition state, and the operation is prohibited. In some cases, internal processing may not be executed.

  The web content display unit 12 displays web content such as HTML to be shared, and the dynamic change detection unit 13 is embedded by the embedding process of the embedding unit 105. Note that, when the WEB content has a frame structure, the dynamic change detection unit 13 is embedded for each frame and the present embodiment can be applied. However, in the description of the present embodiment, the case of applying to the frame A 106 will be described. To do.

  The dynamic change detection unit 13 includes a page transition detection unit 131 that detects the start of page transition of WEB content, and an operation detection unit 132 that detects a state change with respect to a process by an operation such as click or input or an internal process.

  Next, the overall operation of the present embodiment will be described in detail with reference to the flowcharts of FIGS.

  First, when the user performs an operation such as a click on the web content being shared (step S601), the operation detection unit 132 detects a dynamic change due to this operation (step S602), and determines an operation category. Call the unit 1041. The operation detection unit 132 can be implemented using, for example, a Java (registered trademark) Script event, and FIG. 8 shows an example thereof. In the example of FIG. 8, an onclick event occurs when clicked, and the onSync function that is the operation classification determination unit defined in the top.control frame that is the WEB content control unit is called, and which element of which frame is included in the onSync function I have information about what events have occurred. In this manner, the operation classification determination unit 1041 can be called by detecting a dynamic change.

  The operation classification determination unit 1041 inquires of the operation execution unit 1043 whether it is a dynamic change caused by a sharing command or a dynamic change caused by a user operation (step S603). Since the operation execution unit 1043 is not operating and is a dynamic change caused by a user operation, the execution suppression unit 1042 suppresses the execution of this process (step S604). Simultaneously with the suppression, the shared command issuing unit 1022 generates a shared command including information on what operation event is applied to which element of which frame, for example, script code “doSync (FrameName, ElementID, EventName);” Then, the communication unit 101 is used to transmit to the shared command transfer unit 22 (step S605). FIG. 9 shows an example of the operation classification determination unit 1041 using Java (registered trademark) Script. In this example, the process of inquiring the operation execution unit is realized by using a flag variable doSyncFlag. The flag variable doSyncFlag is set to the value true when the operation execution unit 1043 executes internal processing. When internal processing is executed by a shared instruction (when doSyncFlag! = True), the shared instruction issuing unit 1022 defined as a send function is called, and a Java (registered trademark) Script event is used as a method for suppressing the execution of the process. Shows how to stop execution by returning false. In the case of execution of processing by user operation (when doSyncFlag == true), the processing is terminated after the flag variable doSyncFlag is cleared.

  When receiving the shared command (step S801), the shared command transfer unit 22 temporarily stores the shared command in the temporary storage unit 222 (step S802). The transfer unit 223 acquires the sharing command from the temporary storage unit 222 in the order in which the sharing command is received, and transfers it to all users including the sender of the sharing command (step S803).

  Next, when the communication unit 101 of the WEB browser receives the sharing command (step S901), the sharing command determination unit 1021 selects a call destination corresponding to the content of the sharing command (step S902). Since the sharing command is operation information for the WEB content, the operation execution unit 1043 executes internal processing for the WEB content (step S903). Note that the operation execution unit 1043 can also search the embedded state storage unit 1032 and not execute internal processing if even one piece of data is incomplete. The operation execution unit 1043 can be implemented using, for example, the DHTML technology. When the DHTML technology is used, an internal process for an operation such as a click can be dynamically executed.

  The operation detection unit 132 detects the dynamic change again (step S602). As a result of the inquiry to the operation execution unit 1043 (step S603), the operation detection unit 1321 is an internal process using a shared command. Exit without stopping execution.

  Next, when a page transition occurs as a result of the above operation (step S701), the page transition detection unit 131 detects this page transition (step S702), calls the operation prohibition unit 1033, and the web content by the user. The operation is prohibited, and at the same time, the data in the embedding state storage unit 1032 is changed to the incomplete embedding state (step S703). The page transition detection unit 131 can be implemented using, for example, a Java (registered trademark) Script event, and FIG. 10 shows an example thereof. In the example of FIG. 10, the onbeforeunload event of WEB content occurs at the start of page transition, and the onPageChange function that is the operation prohibition part defined in the top.control frame that is the WEB content control part is called. I have my own window object. In this way, the operation prohibition unit 1033 can be called upon detecting the start of page transition. FIG. 11 shows two examples of the operation prohibition unit 1033. In both cases, a technique called CSS (Cascading Style Sheet) that controls the display state of the WEB browser is used to prohibit the operation by the user. I have to. Furthermore, FIG. 12 is an example of the data structure of the embedding state storage unit 1032. For example, the data in the first row of the table indicates that the embedding of the frame A of the WWW browser of the user 1 (self) is completed. In addition, as shown in other rows, data can be held independently for each frame.

  The WEB content performs page transition while the operation is prohibited (step S704). When the page transition is completed (step S705), the embedding unit 105 performs embedding processing, and the dynamic change detection unit 13 including the page transition detection unit 131 and the operation detection unit 132 is embedded in the web content (step S706). When the embedding unit 105 finishes the embedding process, the shared instruction issuance unit 1022 is called, and information indicating which user's embedding process has been completed, such as the script code “doAttachComplete (UserName, FrameName);”. The embedded processing completion notification is generated and transmitted to the shared command transfer unit 22 using the communication unit 101 (step S707). As an example of the embedding processing technique, a method in which the WEB content control unit 11 periodically monitors the WEB content that performs page transition, detects the completion of the page transition and calls the embedding unit, and the WEB content relay unit 21 receives the WEB content. There is a method of adding a tag such as a script for calling an embedding unit before sending to a WEB browser.

  When receiving the shared command (step S801), the shared command transfer unit 22 temporarily stores the shared command in the temporary storage unit 222 (step S802). The transfer unit 223 acquires the sharing command from the temporary storage unit 222 in the order in which the sharing command is received, and transfers it to all users including the sender of the sharing command (step S803).

  When the communication unit 101 of each user's WEB browser receives the sharing command (step S901), the sharing command determination unit 1021 selects a call destination corresponding to the content of the sharing command (step S902). Since the shared command is an embedded processing completion notification, the operation prohibition canceling unit 1031 registers the embedded completion data in the embedded state storage unit 1032 (step S904). The operation prohibition canceling unit 1031 searches whether the embedment process for all users sharing the web content that is the target of the current embedment process has been completed after the registration of the embedding completion data (step S905). If the embedding process has not been completed by all users, the process ends. If the embedding process has been completed by all users, the operation prohibition is canceled for the web content that has been prohibited from being operated (step S906). )finish.

  As described above, according to the present embodiment, the execution of the processing by the operation in the WEB browser is temporarily suppressed, and the internal processing for the operation is executed again through the sharing command transferred from the shared server. Even if the operations A and B are performed simultaneously, the order in which the processes for the operations are always executed is the same. For this reason, for example, even when different elements are clicked at the same time in the WEB content whose behavior changes depending on the order of the elements to be clicked, the behavior among users is equal.

  In addition, the operation is prohibited at the time of page transition, and the operation is not possible until all users can detect the dynamic change after the page transition is completed.

  If the internal processing is not executed when the WEB content is in the operation prohibited state, the execution of the internal processing when the shared command is received during the page transition can be suppressed. For example, when a plurality of users click different links at the same time, it is possible to execute only the link click information previously transferred from the shared server.

  Next, a second embodiment of the present invention will be described with reference to the drawings.

  In the first embodiment, the page transition of the WEB content is detected for each frame and the operation of the frame is prohibited, thereby preventing the user from performing the operation at the time of the page transition. However, when the page transitions, the frame configuration may change. In particular, as a result of the page transition, when the WEB content of the frame further has a frame configuration and a child frame is generated, an operation during page transition is prohibited in the parent frame (a frame including the child frame). Since the generated child frame is in a prescribed state, that is, an operable state, there is a possibility that the embedding process of the dynamic change detection unit in the child frame is not completed even when the operation prohibition state of the parent frame is released. In other words, if the parent frame can be manipulated, the child frame can be manipulated, but there is no guarantee that the child frame can be synchronized at this time.

  In order to solve this problem, in the present embodiment, at the timing when the prohibition of operation of the parent frame is released, the completion status of the child frame embedding process is searched for all users, and If the embedding process is not completed, the configuration shown in FIG. 13 is used instead of the configuration shown in FIG.

  Referring to FIG. 13, compared to FIG. 3, a child frame operation prohibition unit 1034 is added, and the parent frame 106 (referred to as frame A in FIG. 2) includes a child frame 1061. The parent frame 106 and the child frame 1061 are defined for convenience in order to show a relative inclusion relationship when a certain WEB content has a frame configuration, and the child frame 1061 is also recursively described in the present embodiment. And can be considered as a parent frame.

  The child frame operation prohibition unit 1034 is called from the operation prohibition release unit 1031 and searches the embedding state storage unit 1032 when the child frame 1061 exists, and if there is a user who does not have the data of the child frame embedding completion state. If the embedding process of the child frame 1061 has not been completed by all users, the operation of the child frame 1061 is prohibited.

  The components other than the child frame operation prohibition unit 1034 are the same as those in the first embodiment.

  Next, the overall operation of the present embodiment will be described in detail with reference to the flowcharts of FIGS. 4 to 6 and FIG. Compared with the first embodiment, the flowchart of FIG. 7 is replaced with FIG.

  First, the user performs an operation on the WEB content being shared, the steps until the execution of the processing for this operation is suppressed and the sharing command is issued (steps S601 to S605), and the transfer server receives the sharing command. The steps to transfer (steps S801 to S803) and the steps (steps S901 to S903, S601, and S603) until the WEB browser receives the transferred sharing command, executes internal processing for the operation, and ends. This is the same as in the first embodiment.

  Next, when a page transition occurs as a result of the above operation, steps (steps S701 to S707) until a sharing command that is an embedding process completion notification is issued, and a transfer server receives and transfers the sharing command ( Steps S801 to S803) and steps (steps S1601, S1602, S1604, and S1605) from when the WEB browser receives the transferred sharing command and searches for the embedded state are the same as in the first embodiment.

  As a result of searching for the embedding state, when the embedding process of all users is completed, the child frame operation prohibition unit 1034 checks whether or not the child frame 1061 exists (step S1606).

  If there is no child frame 1061, the operation prohibition release unit 1031 cancels the operation prohibition of the parent frame 106 and the process ends (step S1607).

  If the child frame 1061 exists, the child frame operation prohibition unit 1034 further searches the embedded state storage unit 1032 to check the embedded state of the child frame 1061 (step S1608).

  If all the users have been embedded in the child frame 1061, the operation prohibition canceling unit 1031 cancels the operation prohibition of the parent frame 106 and ends (step S1607).

  If all users have not been embedded in the child frame 1061, the child frame operation prohibition unit 1034 prohibits the operation of the child frame (step S1609), and the operation prohibition release unit 1031 prohibits the operation of the parent frame 106. The process is canceled and the process ends (step S1607).

  As described above, according to the present embodiment, when the parent frame 106 is page-shifted and the operation prohibition state is released, if the child frame 1061 needs to be operation-prohibited, that is, all uses If the embedding process of the dynamic change detection unit 13 in the child frame 1061 is not completed, the parent frame 106 itself cancels the operation prohibition after the parent frame 106 sets the child frame 1061 in the operation prohibited state. Even when the child frame 1061 is generated by the page transition and the frame configuration is changed, the user operation on the child frame 1061 at the time of the page transition can be prevented.

  Contrary to the description of the present embodiment, when a WEB content having a frame configuration transitions to a non-frame WEB content, the start of page transition of the parent frame and the child frame is detected and the operation is prohibited. However, since the child frame disappears with the page transition of the parent frame, the user operation can be prevented if the first embodiment is applied to the parent frame without being particularly conscious of the child frame. .

  Each of the above-described embodiments is a preferred embodiment of the present invention, and various modifications can be made without departing from the scope of the present invention. For example, the processing for realizing the functions of this system is performed by causing each device to read and execute a program for realizing the functions of the WEB browser 1, the shared server 2, and the WEB server 3 in the above-described embodiment. Also good. Further, the program is transmitted to another computer system by a transmission wave via a CD-ROM or a magneto-optical disk that is a computer-readable recording medium, or via the Internet or a telephone line that is a transmission medium. Also good.

However, for each configuration and function in which each function is realized as one computer system. Of course, the present invention can also be applied to a configuration in which a plurality of server devices and the like are added.
