BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for displaying a document on a client in a client-server system constituted by a plurality of computers connected to a communication network, and more particularly, to a client WWW (World Wide Web). On the World Wide Web) browser, ie on the web (Web) browser,
A dynamic display method of a document for instantly changing the display of at least one other document of the plurality of documents by an operation input on one of the plurality of documents divided and displayed by the frame The present invention relates to a dynamic document display system and a computer-readable recording medium that records the program.

[0002]

2. Description of the Related Art A client-server system including a plurality of computers connected to a communication network includes a server (server computer) and a client (client computer) which is a user terminal system for the server. A WWW server and a web browser (WWW browser) on the WWW that constructs the Internet are also a kind of client-server system.

In a conventional client-server system of this type, a plurality of documents may be displayed on a screen of a web browser as a client by dividing the document into frames. That is, the HT that describes the document
Using the concept of frames by ML (Hypertext Markup Language), a screen of a web browser is divided into a plurality of frames, and a plurality of documents are displayed by displaying different documents in each frame.

In such a frame-divided display of a plurality of documents, the display content of a document in another frame is changed by an operation input on one frame of the plurality of documents displayed in a divided frame. This is often done. In such a case, a request for a change from the operated document to the WWW server, a process on the WWW server, a download of the changed document from the WWW server, and a display process of the downloaded document are necessary. Becomes Therefore, the update on the web browser requires several seconds to several tens of seconds.

Japanese Patent Application Laid-Open No. 10-105514 discloses W
By using CGI (Common Gateway Interface) program on WW server, HT of displayed document
It is disclosed that the display content is updated without changing the ML syntax. This is a technology for simply reflecting the content corresponding to the download time of the document on the display, whether it is a request based on the operation of the document displayed frame-divided or a normal document, This is for displaying the content corresponding to the request timing.

Japanese Patent Laid-Open Publication No. Hei 10-240605 discloses a means for detecting a change in data provided by a server to a client on a WWW server. It is disclosed that a web browser is requested to reread and the screen is updated. In this case, the WWW server voluntarily updates the display information.

In these systems, in order to change the display information by operating the display document, it is necessary to request the WWW server to update the document by operating the display document. Requesting a change from the operated document to the WWW server "→" Processing on the WWW server "→" Downloading the changed document from the WWW server "→
The update is performed according to a procedure called “display processing of downloaded document”.

[0008]

[Problems to be Solved by the Invention] As described above, "request for change from operated document to WWW server" →
There are two major problems with the update in the order of “processing on WWW server” → “downloading of changed document from WWW server” → “display processing of downloaded document”.

A first problem is that, when a plurality of documents divided into frames are displayed on the same screen of a web browser, information update of another document corresponding to an operation on an arbitrary document is instantaneous. Preferably, it is not performed in less than one second.

[0010] The reason is that a plurality of documents displayed by being divided into frames on the WWW browser are independent from each other while being on the same screen, the documents are static with each other, and passive control between them is not possible. It is impossible.

That is, in order to update the display of one or more other documents by operating one arbitrary document, the update must always be performed via the WWW server. Therefore, the procedure includes WW as described above.
The time required to request the W server to update the document, the time required for processing in the WWW server, the time required for downloading the document from the WWW server,
In addition, a display processing time for performing update display on a web browser is required, and a long time is required for updating information.

A second problem is that, depending on the state of the WWW server and the load on the network, a longer time is required for updating the document. In this case, the time required for updating the document becomes extremely long. Means that the update may fail due to a timeout of the update time.

[0013] The reason is that when the WWW server is connected to many web browsers, the processing assigned to one web browser is reduced, and the processing time is lengthened.

As a result, the time required from the start to the end of the update may be significantly extended. In addition, if the extension of the processing time exceeds the predetermined timeout detection time for the communication processing of the web browser, the web browser stops updating, processes and displays the timeout, and displays the document. The update will be aborted.

The present invention has been made in view of the above circumstances, and mutually controls display contents of a plurality of documents divided by an HTML frame description on the same web browser screen of a client. It is another object of the present invention to provide a method for dynamically and promptly displaying a document to be changed and displayed.

Another object of the present invention is to dynamically and instantaneously control the display contents of a plurality of documents divided by an HTML frame description between documents on the same web browser screen of a client. To provide a dynamic display system of a document to be changed and displayed.

Another object of the present invention is to dynamically and promptly control the display contents of a plurality of documents divided by an HTML frame description between documents on the same web browser screen of a client. Another object of the present invention is to provide a computer-readable recording medium in which a program for executing a dynamic display method of a document to be changed and displayed is described.

02 or 503 analyzes the content, determines what kind of change it is in its own document, and changes its own document to a form that matches the content of the command. By performing this series of procedures mutually, the document 50
Dynamic changes in the display of 1, 502 or 503 can be made.

As described above, the general client
In a server system, when displaying a document in a display area on a web browser of a client machine, the following operation has been performed. From a web browser to WWW
A request is made to the server, and the WWW server uploads the document content according to the request. The web browser arranges and displays the document in the display area divided into frames according to the contents of the downloaded HTML, script language, and the like. That is, conventionally, information exchange between documents has not been performed dynamically even in the same browser.

On the other hand, in each of the above-described embodiments of the present invention, as described above, one of the documents has the TC
P / IP communication server, T for all remaining documents
A function of a CP / IP communication client is provided, and software for performing a process of performing TCP / IP transmission triggered by an operation and a process of receiving TCP / IP is triggered for all documents.

When each document downloaded from the WWW server is displayed on the web browser, the document having the function of the TCP / IP communication server enters a connection request waiting state, and the function of the TCP / IP communication client is disabled. The held document issues a connection request to the TCP / IP communication server until the connection is completed. After the connection is completed, both the TCP / IP communication server and the client enter a standby state.

When the document is operated, the software creates data according to the content of the operation, and
The document is transmitted to the other document by P / IP communication.

The document that has received the data analyzes its contents, determines what kind of change it is in its own document, and changes its own document to a form that matches the contents of the command. By performing this series of procedures mutually, it is possible to dynamically change the display of the document.

According to each of the embodiments of the present invention, the following effects can be obtained.

The first effect is that the update of another document corresponding to the operation on an arbitrary document has been delayed from several seconds to several tens of seconds, but in this embodiment, for example, The change can be made in less than one second.

The reason is that information transmission / reception and update work are performed only in the same computer by TCP / IP communication between documents in the web browser, so that the change processing time for the operation is minimized. Because.

A second effect is that display update in another document corresponding to an operation on an arbitrary document does not fail.

[0097] The reason is that the display update of the document does not involve access to another server or the like, so that it is not affected by the load state of the external network or the state of the server.

The document dynamic display system of the present invention does not need to be configured as a dedicated system.
It can be realized using a normal computer system. For example, by installing a computer system from a medium (a floppy disk, a CD-ROM, or the like) storing a program for executing the above-described operation, a dynamic display system of a document that executes the above-described processing is constructed. can do. By the installation, the program is stored in a medium such as a hard disk in the computer system, configures a dynamic document display system, and is used for execution.

The medium for supplying the program to the computer is not limited to a storage medium in a narrow sense, but may be a communication line,
Like a communication network and a communication system, it may be a storage medium in a broad sense including a communication medium that temporarily and fluidly stores information such as a program.

For example, the program may be registered in an FTP (File Transfer Protocol) server provided on a communication network such as the Internet, and distributed to an FTP client via the network. The bulletin board (BBS: Bulletin) of the communication network may be used. The program may be registered in a board system or the like and distributed via a network. Then, by starting this program and executing it under the control of the operating system, the above-described processing can be achieved. Furthermore, the above-described processing can also be achieved by starting and executing the program while transferring the program via the communication network.
