Description

  The present invention relates to a data input support system, a data input support method, and a program, and more particularly, to a data input support system, a data input support method, and a program using a pull-down list and list box linkage processing in Web-based search processing.

  In recent years, providing various services and data using the Internet or an intranet has become widespread. A user transmits data input using a Web browser installed in a client terminal to a server via the Internet, and the server performs various processes according to the received data and provides data. At this time, the user generally operates the keyboard to input data.

  However, since such data input operation is a heavy burden for unfamiliar users, a simple method is required. For example, an arbitrary one of several candidates using a pull-down list or a list box is required. The device is designed so that items can be selected and entered. Here, since the options in the pull-down list or the like normally need to be programmed in advance in the screen program, it is difficult to deal with the case where the data of the options changes frequently or at every input. is there. For example, if you use the pull-down list to enter the user's address step by step, such as the prefecture name, city name, and town name, the next city corresponding to the input value of the previous prefecture name Correspondence that put ward name into choice was not made.

Patent Document 1 is cited as a document in which a prior art corresponding to such a problem is published. The technique described in Patent Literature 1 generates a postback from a Web browser, searches a database using HTTP communication, and rewrites a pull-down list or list box value on the screen based on the value of the search result. Is. Therefore, when the technique of Patent Document 1 is applied and, for example, an address, for example, a city name, a town name, or the like corresponding to an input value of a prefecture name is input step by step, It is now possible to search the database using HTTP communication for the input value of the prefecture name and put the search result into the choice of the next city name. In the technique described in Patent Document 1, since a postback is generated from a Web browser, changes made in the data form are dynamically reflected in the data source.
JP 2006-107486 A

  However, in the above prior art, since the browser screen is reloaded during data entry, the focus from the target pull-down list is lost.

In FIG. 6A, three pull-down lists 601, 602, and 603 associated with three hierarchical relationships are displayed, and data is stored in the pull-down list 601 associated as the highest hierarchy when initial display is performed. The pull-down list 602 associated as a lower layer of the pull-down list 601 displays data associated with the data selected in the pull-down list 601 when the pull-down list 601 is selected. At this time, the screen is not reloaded. Further, a pull-down list 603 associated as a lower hierarchy of the pull-down list 602 displays data associated with the data selected in the pull-down 602 when the pull-down list 602 is selected. At this time, the screen is not reloaded. Thereafter, by pressing a registration button 604, the input data is transmitted to the server and registered in the DB.

  FIG. 7 is a diagram showing property setting values of the control of the data input support system of FIG.

  In FIG. 7, for a control whose display content is to be dynamically changed, for example, a child control associated as a lower hierarchy, a control ID for identifying a control of a parent control associated as an upper hierarchy is set as a property. With this setting, processing for acquiring an onChange event of the parent control by Java script (Java (registered trademark) Script) is embedded at the time of screen generation. The control ID 701 is a large classification control ID, the control ID 702 is a medium classification control ID, and the control ID 703 is a small classification control ID. A property 704 is a large classification property, a property 705 is a medium classification property, and a property 706 is a small classification property. In FIG. 7, a large classification control ID is set for the medium classification property, and a medium classification control ID is set for the small classification property. As a result, each control is hierarchically related to form a parent, child, and grandchild relationship.

  FIG. 8 is a diagram showing system blocks of the data input support system of FIG. In FIG. 8, at the time of normal screen display such as “initial display” (FIG. 8A), the client 800 requests the web page from the server 801, and the server 801 sends web page data in HTML format to the client 800. return it.

On the other hand, at the time of “pull-down selection” (FIG. 8B), the client 800 requests the server 801 to display data on the web page, and the server 801 returns XML format data to the client 800. This communication is performed by XML-HTTP communication. (Conventionally, a process of requesting a postback from the client 800 and returning data in HTML format from the server 801 has been performed.)
Next, a basic processing flow of the data input support method using the data input support system according to the present embodiment will be described in detail with reference mainly to FIGS. 6A to 6D, 9A, and 9B. For convenience of explanation, a corresponding JavaScript (Java (registered trademark) Script) No. Is also written.

  9A and 9B are flowcharts showing a procedure of data input support processing executed by the client terminal device and the server device in the data input support system of FIG.

  In the “initial display” of FIG. 9A, first, the client makes a screen display request to the server according to the user's instruction (step S901). Here, the request by the client is made by HTTP communication.

  Next, the server acquires a major classification 501 and a name 504 as values used for screen display from an address (ADDRESS) table 500 (see FIG. 5) which is a DB (step S902), and pulls down the acquired value as a pull-down 601 (FIG. 5). 6A) (step S903). Next, the server generates a parent pull-down data acquisition function based on the control properties 705 and 706 (see FIG. 7), and sends the data acquisition function (Java script (Java®) to the onChange event handler. Script) 1003) is generated (step S904). Next, the server generates a data storage function (Java Script 1004) for its own control based on the control IDs 702 and 703 (see FIG. 7) of the control (step S905).

  Thereafter, the client displays the generated screen on the browser (step S906). The screen at this time is the “initial display” screen in FIG. 6A.

  Next, at the time of “pull-down 1 selection (corresponding to FIG. 6B)” in FIG. 9B, the client selects the pull-down list (input data specifying means) and simultaneously changes the Java script (Java (registered trademark) Script) on-change ( onChange) event handler is used to recognize that the pull-down is selected (Javascript (Java (registered trademark) 1003)) (step S911), and the pull-down Value value is acquired (Javascript (registered trademark)). ) Script) 1003) (step S912) (specific data acquisition means). For example, when Tokyo is selected, the [Value] value is “1” (the value of the large classification 501 big_cd) (see FIGS. 5 and 6B).

  Next, the client transmits the Value value acquired in step S912 to the server by XML-HTTP communication (Java (registered trademark) 1003) (step S913) (transmission means).

  On the other hand, the server receives the pull-down Value value transmitted from the client (Java Script (Java (registered trademark) 1005)) (step S914) (reception unit), and DB (data storage unit) based on the received data. ) To obtain the major classification 501, middle classification 502, and name 504 (Java (registered trademark) Script 1005) (step S915) (retrieval means).

At this time, the SQL statement for operating the relational database is, for example, as follows.
[SQL statement]
SELECT big_cd, middle_cd, name
FROM ADDRESS
WHERE big_cd = “1”
AND middle_cd! = “0”
AND small_cd = “0” (See Figure 5)
Next, the data acquired in step S915 is converted into data in XML format. (Java Script 1006) (Step S916).

 [XML]

  Next, the server transmits the XML data converted in step S916 to the client through XML-HTTP communication (Java (registered trademark) 1006) (step S917) (transmission means).

  Next, the client receives the data transmitted from the server (Java Script 1004) (step S918) (data receiving means), and reflects the received data as option data of the pull-down 602. (Step S919) (setting means) This processing is terminated. When the process is completed, the screen becomes the screen at the time of “select pull-down 1” in FIG. 6B. Thereafter, for example, “Shibuya Ward” is selected by the user.

  Next, the case of “pull-down 2 selection (corresponding to FIG. 6C)” will be described.

  The selection of pull-down 2 is performed according to the selection of pull-down 1, and will be described with reference to the flowchart of FIG. 9B.

When pull-down 2 (602) is selected, the client first uses the on-change event handler of Java Script (Java (registered trademark)) simultaneously with the selection of the pull-down list to confirm that the pull-down is selected. Recognize (Java (registered trademark) 1003) (step S911), and then obtain a pull-down Value (Java script (registered trademark) 1003) (step S912). If Shibuya Ward is selected, [Value]
“1” (value of big classification 501 big_cd)
“2” (value of middle classification 502 middle_cd)
It becomes.

  Next, the client transmits the Value value acquired in Step S912 to the server by XML-HTTP communication (Java (registered trademark) 1003) (Step S913).

  On the other hand, the server receives the pull-down Value value transmitted from the client (Java Script 1005) (step S914), searches the DB based on the received data, and performs the major classification 501; The middle classification 502 and the name 504 are acquired. (Java Script 1005) (step S915).

At this time, the SQL statement for operating the relational database is, for example, as follows.
[SQL statement]
SELECT big_cd, middle_cd, small_cd, name
FROM ADDRESS
WHERE big_cd = “1”
AND middle_cd = “2”
AND small_cd! = "0" (See Fig. 5)
Next, the data acquired in step S915 is converted into data in XML format. (Java Script 1006) (Step S916).

 [XML]

  Next, the server transmits the XML data converted in step S916 to the client through XML-HTTP communication. (Java Script 1006) (Step S917).

  Next, the client receives the data transmitted from the server (Java Script 1004) (step S918), reflects the received data as option data of the pull-down 603 (step S919), and This process ends. When the processing is completed, the screen becomes the screen at the time of “select pull-down 2” in FIG. 6C.

  Next, Ebisu or Hatsudai is selected by pull-down 3 (603) by the user's operation, and then the user registration screen is completed by entering the address, telephone number, etc. as necessary (FIG. 6D). By detecting that the registration button has been pressed, data is transmitted to the server and registered in the server DB.

  9A and 9B, after the client recognizes that the pull-down has been selected using the on-change event handler of JavaScript (step S911), the client acquires the value value of the pull-down and obtains the server. (Step S912, Step S913), the server searches the DB based on the Value value received from the client (Step S915), converts the search result into XML format data, and then transmits it to the client ( Since step S916 and step S917) are performed, XML-HTTP communication using Javascript and XML can be performed in the background, and the pull-down list can be rewritten without causing a postback from the Web browser. At this time, since the screen is not reloaded and the focus can be maintained, for example, it is possible to eliminate a cumbersome user operation of repeatedly scrolling for each input in the pull-down operation.

  In this embodiment, the example in which the three pull-down lists 601, 602, and 603 are displayed in advance has been described. However, only the pull-down list 601 is displayed in step S906, and the pull-down list is displayed in the process of step S919. 602 (same for 603) may be displayed.

  Next, a basic implementation method of the data input support method shown in FIGS. 9A and 9B will be described.

  FIG. 10 is a diagram showing a mounting method in the data input support system of FIG.

  In FIG. 10, when the drop-down list (DropDownList) 1001 that is the upper control is selected, the above-described “pull-down 1 selection” processing steps S911 to S919 in FIG. 9B are executed. That is, the selected value is set as an argument, a server module call function is called, and is sent to a drop-down list component. At this time, the drop-down list (DropDownList) component acquires the selected Value value of the parent drop-down list, and acquires a list to be set in the child drop-down list based on this Value value. Next, the drop-down list (DropDownList) component converts the content of the acquired list into the XML format and sends it to the client as a return value. Next, the client parses the XML that is the obtained return value (Parse), and generates and adds an option of the child drop-down list. In this way, an option for a child drop-down list is formed, and data is reflected in a drop-down list (DropDownList) 1002 which is a lower control.

  According to the present embodiment, by using a plurality of controls associated with each other in a hierarchical relationship and further using a technology using XML-HTTP communication, a postback is generated from a Web browser and HTTP communication is not performed. Since XML-HTTP communication is performed in the background using Java Script (Java Script) and XML, the pull-down list can be rewritten without causing a post-back from the Web browser. The speed can be increased and the focus of the target pull-down list can be maintained. In other words, according to the present embodiment, master data using a pull-down list in Web-based search processing is processed in accordance with pull-down linked processing (in accordance with the value of one pull-down in a form in which post-back is not generated from a Web browser by XML-HTTP communication. And other pull-down collections).

  In the present embodiment, the address input support system and the input support method using the hierarchical relationship of controls have been described. However, the present invention selects, for example, one keyword in customer information operation in a specific field, The present invention can also be applied when narrowing down customer information by displaying a plurality of customer data associated with a keyword and selecting another keyword common to a part of the displayed customer data. In the present invention, the number of text boxes corresponding to one control ID is not limited to one, and a plurality of text boxes can be associated with one control ID.

  In addition, the present invention can take the form of, for example, a system, apparatus, method, program, storage medium, and the like, and can be applied to a system including a plurality of devices. It can also be applied to an apparatus comprising:

  The object of the present invention can also be achieved by executing the following processing. That is, a storage medium storing software program codes for realizing the functions of the above-described embodiments is supplied to a system or apparatus, and the computer (or CPU, MPU, etc.) of the system or apparatus is stored in the storage medium. This is a process of reading the program code.

  In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiments, and the program code and the storage medium storing the program code constitute the present invention.

  Moreover, the following can be used as a storage medium for supplying the program code. For example, floppy (registered trademark) disk, hard disk, magneto-optical disk, CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-RAM, DVD-RW, DVD + RW, magnetic tape, nonvolatile memory card, ROM or the like.
