JP4720971B2 - Content display method - Google Patents

Description

The present invention relates to a content display method in a client-server system using a network, to a content display method for controlling the input operations in the content according to particular type of level or the client terminal operator who operates the client terminal .

2. Description of the Related Art Conventionally, a client / server system including a server connected to a network such as the Internet or a LAN and a client terminal connected to the network and requesting various processing requests from the server is known (for example, (See Patent Document 1). In this type of client / server system, a client terminal accesses a server as necessary to perform desired processing or exchange of data. For example, when browsing the data server maintains at the client terminal, the client terminal, requesting that outputs data to the server (download). In response to this download request, the server provides desired data to the client terminal via the network. On the other hand, the client terminal receives this data, browsing and displayed, for example, on a display device.

In the client / server system, when the data stored on the server side is viewed on the client terminal using the method described above, display information described in HTML, for example, is prepared on the server. Then, the client terminal downloads display information described in HTML held by the server as necessary, and displays the downloaded information on the display device using browser software of the client terminal .

For example, when an Internet shopping system is constructed using such a server / client system , the same screen is displayed on the client terminal operated by the operator and another client terminal operated by the customer. The product purchase can be performed smoothly by supporting the operation. Specifically, it is possible to display the contents instructed on the screen by the operator (for example, the position of the mouse and the cursor) on both display devices, and purchase a product while mutually confirming the display contents .
In other words, in such an Internet shopping system, the position of the mouse or cursor designated by the operator is reflected in synchronization with the client terminal on the customer side, and the customer presses the product purchase button with the operation support. Is operated. Alternatively, instead of a customer who is unfamiliar with the terminal operation, so-called input substitution is also performed in which an operator inputs a product number and an order quantity while browsing the same screen as the customer (see, for example, Patent Document 2). Such an Internet shopping system has an advantage that appropriate operation (purchase) support can be provided to a customer unfamiliar with the operation of the client terminal.
JP 2001-14244 A JP 2002-109147 A

When an Internet shopping system is constructed using the above-described client / server system , the same information is synchronously displayed on the operator-side client terminal and the customer-side client terminal . For this reason, there has been a problem that the operator presses, for example, a product purchase button or a settlement button displayed on the client terminal on the operator side intentionally or accidentally.

In order to solve this problem, the display information displayed on the client terminal on the operator side and the display information displayed on the client terminal on the customer side are stored in the server differently, and the display information required for each client terminal is stored. Download from the server and execute . However, on the other hand, it is necessary to prepare display information corresponding to each client terminal in advance and hold it in the server. For this reason, there are problems such as an increase in the number of man-hours for creating the display information and maintenance man-hours, and an increase in the storage capacity required for storing the display information.

The present invention has such a the conventional circumstances been made in addressing, its purpose is to limit the input operation according to the type of the operator level (operation authority) or a client terminal operated by the client terminal Another object of the present invention is to provide a content display method capable of performing the above.

In order to achieve the above-described object, the content display method according to the present invention is the same content distributed from the server at the plurality of client terminals in the client / server system in which the server and the plurality of clients are respectively connected to the network. When displaying the screen of
Adding setting information for disallowing an input operation included in the content to the content held in the server and distributed to the client terminal;
The server transfers a control application program that validates the setting information to a client terminal that should set the input operation included in the content to non-permitted, while validating all the input operations included in the content. A control application program for invalidating the setting information is transferred to the client terminal to be
Each client terminal, to set the permission or non-permission of the input operations in the in the control application program transferred thus to enable or disable the setting information added to the content the content from the server It is a feature.

The input operation is performed by pressing a button or check box displayed on the browser of the client terminal , selecting a list, and inputting characters into a text area.
Preferably, the server includes an application server that holds the control application and a content server that holds the content.

According to the content display method of the present invention as described above, provided with a configuration information content itself is set to a non-allowed input operations included in the content, the client terminal, the type of the client terminal prior to the display of content The control application program corresponding to the content is downloaded in advance, and the setting information included in the content is validated or invalidated. Therefore, for each type of client terminal, it is possible to set permission or non-permission of input operations such as buttons, check boxes, lists, and text areas included in the content.

Further, when the above-described Internet shopping system is constructed by applying the content display method of the present invention, even if the same content information is synchronously displayed on the client terminal on the operator side and the client terminal on the customer side, the operator The input operation such as a product purchase button on the side can be invalidated. Therefore, the operator cannot press the product purchase button displayed on the client terminal on the operator side intentionally or accidentally. Furthermore, there is no need to separately prepare content displayed on the client terminal on the operator side and content displayed on the client terminal on the customer side. Therefore, content creation and maintenance are easy, and the data storage capacity of the server does not increase.

Hereinafter, a content display method according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a client / server system to which a content display method according to an embodiment of the present invention is applied. In this figure, 1 is a network (communication line) such as a LAN or the Internet. Although details will be described later, in the network 1, for example, a plurality of client terminals 10, a control application server 20, and a content server 30 are connected to each other to construct a so-called client-server system. Incidentally, FIG. 1 shows an example in which an Internet shopping system is configured by providing client terminals 10 operated by an operator and a customer, respectively. FIG. 1 shows an example of the embodiment of the present invention, and the scope of the present invention is not limited by this figure.

The control application server 20 holds a control application program 21 for controlling the operation (display control) of the content transferred to the client terminal 10, which will be described in detail later, in the program storage unit 22. The control application program 21, which has been prepared in accordance with the type of level and the client terminal 10 of the operator who operates the client terminal 10, adapted to be downloaded to the client terminal 10 via the network 1 ing. Specifically, the control application program 21 includes a control application program 21a that validates the setting information for setting an input operation included in the content 31 described later to non-permission , and a control application program 21b that invalidates the setting information. It is made up of.

The content server 30 is provided with a content storage unit 32 that holds content 31 that is operated by the control application program 21 downloaded from the control application server 20. The content 31 is distributed to the client terminal 10 via the network 1 by the delivery request from the client terminal 10. Further details will be described later, this content 31, setting information for setting the non-authorized input operations included in the content 31 is provided by the control application program 21 by the client terminal 10 downloads.

On the other hand, the client terminal 10, the operation input unit 11 (such as, for example, a keyboard) that receives an input operation from the operator of the client terminal 10 and the display unit 12 for displaying a message or the like to the operator of the client terminal 10 (e.g., a display device ) Is provided. In addition, the client terminal 10 is provided with browser software 13 that retrieves and displays desired content 31 from a content server 30 connected to the network 1, and a client storage unit 14 that holds the browser software 13.

In general, in the client system configured as described above, the content display method according to the present invention is characterized by the level (operating authority) of the operator who operates the client terminal 10 and the type of the client terminal. One of the control application programs 21a and 21b is downloaded from the control application server 20, the content 31 is provided with setting information for setting the input operation included in the content to be unauthorized , and the control application The program 21a, 21b makes the setting information valid or invalid, thereby setting the input operation of the content 31 in the client terminal 10 to be permitted or not permitted .

Relates the content display method according to this feature is the invention, an example of the setting information for setting the non-permit input operation incorporated in the content 31, the flow chart of FIG. 3 showing the operation of FIG. 2 and the client terminal 10 It explains while referring to. In the content described in HTML shown in FIG. 2, the line number [1 to 11] is given to the left end of each line for convenience of explanation.

As the control application program 21 held in the control application server 20, for example, a Java (registered trademark) script is used. Then, the non-permission setting of the input operation included in the content 31 is performed using a META tag. The META tag does not affect the content itself, and the present invention has been made paying attention to this point.
Specifically, when the button (input operation) displayed on the display unit 12 of the client terminal 10 is invalidated by the browser software 13, a META tag is described in the content 31 in order to identify the invalidated button. As shown in the line number [3] and the line number [4] in FIG. 2, this META tag includes an attribute of NAME given to an input operation (button) to be invalidated as an attribute for specifying the input operation (button). Set the same value. Here, set the value of "MUKOU" for line number [3] as the same value as the NAME attribute of the button to be disabled, and set the value of "MUKOU2" for line number [4]. ing. And to declare that it is a META tag for invalidating the button, the identifier "IWATSU" is set in the ID attribute. Note that these values and identifiers are not limited to “MUKOU”, “MUKOU2”, and “IWATSU” described in FIG. 2, and may be composed of arbitrary characters or character strings. Of course, it goes without saying that this character or character string may be configured to include numbers and symbols.

The line number [7] sets “MUKOU” which is the same value as the NAME attribute of the META tag declared by the line number [3], and declares that the button is invalid. In line number [8], “MUKOU2”, which is the same value as the NAME attribute of the META tag declared in line number [4], is set. As described above, the setting information of the input operation to be invalidated is registered in the content 31 in advance.
Incidentally, the contents shown in FIG. 2 will be described. Line number [1, 11] is a tag indicating that the content is HTML, and line number [2, 5] is the header part. The line number [6, 10] is a tag indicating that the line number [7-9] is a body part (body).

  In the line number [3, 4], which is the header portion, the value of the button NAME to be invalidated and the identifier indicating the invalidated META tag are declared in the ID as described above. Also, in line number [7-9], which is the body part, line number [7] has an invalid input type (INPUT TYPE = "button") indicating that the operation display to be input is a button. NAME value to be converted (NAME = "MUKOU") is described. Also, in the line number [8], the URL of the reference destination assigned to this button (A HREF = http: //www.jpo.go.jp/indexj.htm) and NAME's to invalidate this URL A value (NAME = "MUKOU2") is described. As described above, for the button to be set for invalidation, the value described in “NAME” and the value of NAME attached to the META tag are described in advance in the content.

On the other hand the client terminal 10, prior to download and display contents 31 held in the content storage unit 32 of the content server 30 as described above, requests download of a control application program 21 from the controlling application server 20 to [step S1]. The control application server 20 that has received the download request from the client terminal 10 determines the type of the client terminal 10 [step S2]. For this type determination, a well-known technique such as that introduced in the above-mentioned input proxy system of Patent Document 2 can be employed. Then, the control application server 20 transfers the control application program 21a that validates the control information to the client terminal 10 that determines that the button needs to be invalidated [step S3]. On the other hand, the control application server 20 transfers the control application program 21b for invalidating the control information to the client terminal 10 determined that the invalidation of the button is unnecessary [Step S4].

Specifically, the client terminal 10 of the operator side in step S3, while transferring control application program 21a to enable the setting information in order to disable button in step S3, the client terminal 10 of the customer In step S4, the control application program 21b that invalidates the setting information is transferred.
In this way, each client terminal 10 downloads one of the control application programs 21 corresponding to the type of the client terminal 10 and then downloads the content 31 held in the content storage unit 32 of the content server 30 [ Step S5].

Then, the operator-side client terminal 10 that has downloaded the control application program 21a for invalidating the button using the setting information first determines whether or not the META tag is present in the content 31 by the control application program 21a [ Step S6]. At this time, if the client terminal 10 on the operator side determines that the ID of the META tag to be invalidated (for example, ID = “IWATSU”) is not present in the content 31 by the control application program 21, the process proceeds to step S6 to step S9. Exit the loop and end the process.

On the other hand, if the client terminal 10 on the operator side includes the ID of the META tag to be invalidated (eg, ID = "IWATSU") in the content 31 in step S6, the NAME value in the META tag is declared, and , Whether the NAME value (NAME = "MUKOU") that invalidates the button described in this META tag matches the input type (INPUT TYPE = "button") indicating that the operation display to be input is a button It is determined whether or not [Step S7]. Next, when the client terminal 10 determines in step S7 that the value of the NAME for invalidating the button described in the META tag is equal to the value of the NAME described in the button, the client terminal 10 invalidates the button [step S8 ]. On the other hand, if the client terminal 10 determines in step S7 that the value of the NAME described in the META tag is not equal to the value of the NAME described in the button, the client terminal 10 does not invalidate the button. Thereafter, the client terminal 10 repeatedly checks whether or not there is a button invalidation META tag included in the content 31 transferred from the content server 30 [step S9].

Since the control application program 21b downloaded to the client terminal 10 on the customer side invalidates the control information itself, the value and identifier described in the META tag are not performed without performing the above-described process of invalidating the button. Is ignored. That is, the client terminal 10 on the customer side can perform a button input operation.
Thus, according to the content display method according to the present invention configured as described above, since the META tag for disabling (invalidating) the button operation is described in the content 31 held in the content server 30, the client terminal If the control application program 21 according to the level of the operator who operates 10 and the type of the client terminal is downloaded from the control application server 20, the setting information is validated or invalidated. It may be allowed or not allowed to enter operations included in the content. That is, it is sufficient to prepare the common content 31 in the content server 30 regardless of whether or not the input operation is permitted or not permitted. Therefore content display method according to the present invention, it becomes possible to perform the creation and maintenance of the content 31 easily enter the client terminal 10 in response to the operator's level operating the client terminal 10 (operation authority) The operation can be restricted.

The present invention can be implemented with various modifications without being limited to the above-described embodiments. For example, in the above-described embodiment, the client / server system in which the control application server 20 and the content server 30 are prepared for easy understanding is illustrated. However , the control application server 20 and the content server 30 are illustrated. Of course, it does not matter if it is constructed as a system in which these are combined into one server. Thus, if the servers are unified, a system can be constructed more easily.

In the above-described embodiment, the client terminal 10 previously downloaded the control application program 21 from the control application server 20 and then displayed the content 31 held by the content server 30. In addition, an instruction to download the control application program 21 held by the control application server 20 may be incorporated. In this case, it is more preferable that the operator of the client terminal 10 can automatically set permission or non-permission of button operation without being aware of downloading of the control application program 21.

In the above-described embodiment, the processing for invalidating the buttons in the content 31 is exemplified. However, in addition to the text box, list, radio button, check box, text area, and the like that can be input from the browser. application of content display method according to the present invention are possible. Specifically, a META tag may be described in the content 31 as shown in a setting example in which these input operations are not permitted in FIG. Incidentally, in the content described in HTML shown in this figure, the line number [100 to 190] is given to the left end of each line for convenience of explanation.

In this figure, the line number [100, 190] is a tag indicating that it is HTML, the line number [110-116] is a META tag indicating invalidation, and the line number [120-180] is the body part (body). is there. In this body part, the line number [130 to 132] is the text box invalidation, the line number [140 to 146] is the list invalidation, the line number [150 to 154] is the radio button invalidation, and the line number [ 160-162] indicates invalidation of the check box, and line numbers [170-172] indicate invalidation of the text area. Incidentally, in the body part, line numbers [130, 140, 150, 160, 170] are comment sentences clearly indicating what invalidation processing is being performed, and line numbers [132, 146, 154, 162, 173] are blanks that add a blank line so that the display of adjacent processing (input operation) is easy to see on the display unit 12 of the client terminal 10.

  Now, in this figure, the META tag for invalidating the input operation is described in the header part of the line number [110 to 116]. First, NAME (NAME = "HOSHI") and ID (ID = "IWATSU") for invalidating the text box are described in the line number [111]. Next, line number [112] describes NAME (NAME = "DAENN") and ID (ID = "IWATSU") for invalidating the list. The line number [113] describes NAME (NAME = "MARU") and ID (ID = "IWATSU") for invalidating the radio button. Line number [114] describes NAME (NAME = "SHIKAKU") and ID (ID = "IWATSU") for invalidating the check box. In line number [115], NAME (NAME = "SANKAKU") and ID (ID = "IWATSU") for invalidating the text area are described. Note that these NAME and ID are not limited to the above-described character strings, and may be composed of arbitrary characters or character strings. Of course, this character or character string may be configured to include numbers and symbols.

Line number [131] describes NAME = "HOSHI", which is the value of NAME that invalidates the text box, together with INPUT TYPE = "text" of the type declaration statement indicating the text box.
In line number [141], a type declaration SELECT indicating a list and SIZE = "1" which is a value of SIZE indicating the size are declared, and NAME = which is a NAME value which invalidates the list. "DAENN" is entered. The line number [142 to 144] describes an option indicating the contents of the list, and the line number [145] describes a tag indicating the end of the list declaration.

Line numbers [151 to 153] describe NAME = "MARU", which is a value of NAME for invalidating each radio button, together with INPUT TYPE = "radio" of the type declaration indicating the radio button.
Line number [161] describes NAME = "SHIKAKU", which is the value of NAME that invalidates the check box, as well as INPUT TYPE = "checkbox" of the type declaration indicating the check box.

In line number [171], TEXTAREA which is a declaration indicating the text area, ROWS = "8" (8 lines) and COLS = "30" (30 columns) indicating the number of rows and columns of this text area, NAME = "SANKAKU" which is the value of NAME that invalidates this text area is described. In line number [172], a tag indicating the end of the text area declaration is described.
For the input operation to be invalidated in this way, the level of the operator who operates the client terminal 10 by declaring the NAME value and the ID (identifier) identifying the invalid META tag in advance in the META tag Control on the client terminal 10 side can be restricted according to (operation authority).
