  However, the technique of Patent Document 1 does not have a function to prevent an operation for erasing information, and an operation for transitioning to a screen on which an operation for erasing information is performed is necessary.

  In addition, since the loss of information is prevented by storing the information to be lost in the Web application, the client terminal must always be connected to the network, and the information is lost when the network is disconnected. Can not prevent.

  Even in a function that does not need to prevent loss of information, such as a screen that only searches for information, information is transmitted from the Web browser to the Web application, and unnecessary traffic flows through the network.

  The present invention has been made to solve the above-described problems, and prevents an operation in which information is lost in advance, prevents loss of information including when the network is disconnected, and sends unnecessary traffic to the network. It is to provide a mechanism that does not flow.

  The present invention is an information processing apparatus that can be connected to a Web server on which a Web application operates, and changes to a screen display based on control of a forced termination button and / or business processing software that forcibly terminates the screen display displayed on the display unit. An information processing apparatus having a web browser for displaying a screen transition button to be displayed on a display unit, wherein the web application receives the web page information from the web server, and the web application receives the web page information received by the receiving unit. A determination unit that determines whether or not a registration item to be registered is included, and if the determination unit determines that a registration item is included in the Web page information, stores a value of the registration item of the received Web page information The initial Web page storage means to which the registration item is included by the determination means When the b page information is displayed and the forced end button or the screen transition button is pressed, the input value to the registration item when the button is pressed and the registration stored in the initial Web page storage means Difference detection means for detecting a difference from the value of the item, and screen transition confirmation means for confirming whether to execute a process of forcibly terminating or transitioning the screen display when a difference is detected by the difference detection means It is characterized by that.

  According to the present invention, it is possible to reduce the time required for an operation for transitioning to a screen on which an operation in which information is lost is performed by preventing an operation in which information is lost.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system configuration diagram showing a configuration of an information processing system according to the present invention.

  In FIG. 1, in the information processing system, at least one Web application server 110 and a client terminal (information processing apparatus) 100 for displaying Web application data through a Web browser are connected via the Internet 120.

  The user browses data displayed by the web application of the web application server 110 from the client terminal (information processing apparatus) 100 through the web browser, and the user performs processing for inputting data to the web application through the web browser. .

  FIG. 2 is a diagram showing a hardware configuration of various terminals according to the embodiment of the present invention.

  In FIG. 2, the CPU 201 comprehensively controls each device connected to the system bus 204.

  The ROM 202 or the external memory 211 stores an operating system (OS) that is a control program of the CPU 201 and programs for realizing various functions described later of each server or each client.

  The RAM 203 functions as a main memory, work area, temporary save area, and the like for the CPU 201.

  The input controller 205 controls input from the input unit 209. Examples of the input unit 209 include a pointing device such as a keyboard and a mouse in a terminal such as a server or a client. Moreover, in a printing apparatus etc., a touch panel, a button, a switch, etc. are mentioned.

  The output controller 206 controls the display of the output unit 210. Examples of the output unit 210 include a CRT and a liquid crystal display.

  The external memory controller 207 controls access to the external memory 211 that stores a boot program, various applications, font data, user files, edit files, printer drivers, and the like. In addition, various tables and parameters for realizing various functions of each server or each client are stored. Examples of the external memory 211 include a hard disk (HD), a floppy (registered trademark) disk (FD), a compact flash (registered trademark) connected to a PCMCIA card slot via an adapter, and smart media.

  The communication I / F controller 208 executes communication control processing with an external device via a network.

  A program (FIG. 14) for realizing the present invention is recorded in the external memory 211, and is executed by the CPU 201 by being loaded into the RAM 203 as necessary.

  FIG. 3 is a block diagram illustrating a software configuration of the information processing system according to the embodiment of this invention.

  The client terminal (information processing apparatus) 100 includes a receiving unit 302 that receives screen data (Web page information) from the Web application 310 of the Web application server 110 and a display unit 301 that displays the data.

  The client terminal 100 includes a determination unit 303 that determines whether the screen data (Web page information) received from the Web application includes a data registration item for registering data in the Web application. The registration items determined by the determination unit 303 indicate registration items registered in the continuous storage unit 312 that is continuously stored, and input items input to the temporary storage unit 311 that is temporarily stored in the Web application include Not included.

  As a specific example of the registered item, for example, in the case of an input item that only needs to temporarily store a user's input value, such as a search keyword input field, the determination unit 303 may store it in the temporary storage unit 311. It is not judged as a data registration item. On the other hand, an input item of data to be registered in the database 313 in the Web application server 110 such as personal information is determined as a data registration item. By determining this registered item, it is not necessary to hold Web page information that does not need to prevent the loss of information, such as an input item that only searches for information, and client resources are not wasted.

  In addition, when the data registration item for registering data in the Web application is included in the Web page information, the client terminal 100 stores an initial Web page that stores the value of the data registration item in the Web page information received by the receiving unit. A storage unit 304 is included. That is, initial Web page display information is stored.

  In addition, when the client terminal 100 displays Web page information including a data registration item for registering data in the Web application, when the forced public power button or the screen transition button of the Web browser is pressed, the client terminal 100 It has a difference detection unit 305 that detects whether the input value of the registered item when one of the two buttons is pressed is different from the value stored in the initial Web page storage unit 304. That is, unlike the initial Web page display information, it is detected whether there is an item input by the user.

  The client terminal 100 includes a screen transition confirmation unit 306 that displays a confirmation screen as to whether to execute forced termination processing or screen transition processing when the difference detection unit 305 detects a difference. In other words, even if the user accidentally selects screen transition or forced termination by displaying this confirmation screen, the confirmation screen is displayed in advance to the user to prevent the screen from shifting due to an operation error. it can.

  In addition, the client terminal 100 includes an input value storage unit 307 that stores input values of registered items when the forced end button or the screen transition button is pressed, and a Web page that has transitioned with the forced end button or the screen transition button is displayed. When it is displayed again, it has a registration item input unit 308 for inputting and displaying the input value stored in the input value storage unit 307 in the corresponding registration item.

  The client terminal 100 also confirms whether or not to input the input value stored in the input value storage unit 307 into the corresponding registration item when the Web page transitioned by the forced end button or the screen transition button is displayed again. The input value confirmation unit 309 is displayed.

  With the above configuration, a warning screen (confirmation screen) is displayed to the user when the user accidentally presses the forced end button or the screen transition button after entering a value in the registered item in the Web page information with the registered item. Therefore, it is possible to prevent an operation in which information is lost. Even for Web pages with registered items, input items that do not perform registration processing in the Web application, such as input items for inputting search keywords, do not display a warning screen to the user, improving user operability. It is also possible to prevent unnecessary traffic from flowing through the network.

  Hereinafter, the flow of the embodiment of the present invention will be described with reference to FIGS.

  FIG. 4 is a flowchart showing an example of the first control processing means in the information processing system according to the embodiment of the present invention, and S401 to S407 in the figure indicate each step. The processing of each step is realized by the CPU 201 of each device loading and executing an application program stored in the external memory 211 of each device on the RAM 203.

  The flowchart of FIG. 4 is a flow of processing that is started in the client terminal 100 when the user inputs a URL to the Web browser or by an operation such as clicking the link of the Web browser with a mouse.

  First, in step S401, the receiving unit 302 of the client terminal 100 sends a request to a Web server specified by a URL or link input by the user.

  Next, in step S402, when the web application 310 of the web application server 110 receives the request, in step S403, the web application 310 transmits the requested URL file to the client terminal 100.

  Next, in step S <b> 404, the receiving unit 302 of the client terminal 100 receives the Web page information transmitted from the Web application server 110.

  In step S <b> 405, the determination unit 303 of the client terminal 100 analyzes the Web page information received from the Web application server 110 and determines whether there is a registration item to be registered in the Web application 310 in the Web page information. A screen image for registering data in the Web application 310 will be described with reference to FIG.

  FIG. 8 is a schematic diagram showing an example of a screen for registering data in the Web application 310 according to the embodiment of the present invention.

  800 in FIG. 8 is an example of a screen displayed by the Web browser, and input items for user information are arranged in 801. The user inputs each input item 801 and finally presses the [Register] button 802 to confirm the input value and register the input value to the Web application 310.

  An HTML source code example 810 transmitted by the web application 310 to display a screen such as 800 on the web browser is shown.

  810 is an example in which only the main points of 800 HTML source codes are extracted. The HTML source code on lines 4 to 9 of 810 has an element whose element name is “input” and attribute is “type =“ text ””, and this element is an element that accepts data registration by the user. is there.

  For example, the value input in the input field corresponding to “Surname” of 801 is stored as a parameter value having the name attribute “lastName” (813) as a parameter name. Similarly, the value input in the input field corresponding to “Name” 801 is held as a parameter value having the name specified by “firstName” as the name attribute as the parameter name. The parameter values input in the input fields in the rows after 801 are held as parameter values corresponding to the respective parameter names.

  In the case of Web page information having items registered in the Web application 310 as shown in FIG. 8, the process proceeds to Yes in step S405, and the process proceeds to step S406.

  On the other hand, if there is no input item in the Web page information, or if there is an input item but there is no registration item to be registered in the Web application 310, the process proceeds to No, and the process proceeds to step S407. With reference to FIG. 13, a screen image in which there are input items in the Web page information but no registration items to be registered in the Web application 310 will be described.

  FIG. 13 is a schematic diagram illustrating an example of a screen that has input items in the Web page information according to the embodiment of the present invention but does not have registration items to be registered in the Web application 310.

  Reference numeral 1300 in FIG. 13 is an example of a screen displayed by the Web browser, and input items for searching for user information are arranged in 1301. The user inputs any of the input items 1301 and presses a [Search] button 1302 to search the user information with the input value.

  An HTML source code example 1310 transmitted by the Web application 310 in order to display a screen such as 1300 on the Web browser is shown in 1310.

  1310 is an example in which only the main points of 1300 HTML source code are extracted. The HTML source code on line 4 to line 710 of 1310 has an element whose element name is “input” and attribute is “type =“ text ””. This element is an element that accepts data input by the user. is there.

  For example, a value input in the input field corresponding to “last name” 1301 is searched as a parameter value having the name attribute “lastName” as a parameter name.

  The name attribute of the “input” element whose attribute described in the ninth line is “type =“ button ”” is “search” (1311), and the content of this element is the character “search” (1312) Therefore, it can be inferred that the input item 1310 is an input item for the search keyword.

  As described above, when the name attribute of the “input” element is a character including “search”, “find”, or “q”, or the content of the element is “search”, “search”, “search” In the case of characters such as “find”, it is determined that the data is not continuously registered in the Web application 310, and the warning screen (confirmation screen) is not displayed even when the screen transitions. The effect of reducing the troublesomeness can be obtained. In other words, the input items on the search screen disappear without a warning screen at the same time as the forced end button is pressed, reducing the troublesome user operation, reducing the memory consumption of the client, and not sending unnecessary traffic to the network. Get the effect. Returning to the flowchart of FIG.

  In step S405 of FIG. 4, if the Web page information received in step S404 is a screen for registering data in the Web application 310, the process transitions to step S406.

  Next, in step S406, the initial web page storage unit 304 of the client terminal 100 stores the initial value of the input value of the registration item in the web page information received in step S404 in the RAM 203 or the external memory 211 of the client terminal 100. . The data structure to be stored will be described with reference to FIG.

  FIG. 7 is a schematic diagram illustrating a data structure stored in the client terminal (information processing apparatus) 100 according to the embodiment of this invention.

  7 stores a URL requested by the client terminal 100, a unique processing sequence number, and a time stamp at the time of access.

  701 means that there are as many pieces of data as the number of each registered item for 700 processing sequence numbers. Each registered item includes a processing sequence number for each Web page information and a name attribute. The parameter name corresponding to the attribute value and the parameter value input in the corresponding input field are stored.

  In the example of 810 in FIG. 8, “lastName”, “firstName”, and the like correspond to the parameter name, and each parameter value is in an uninput state such as 801, so a blank line is input. Returning to the flowchart of FIG.

  Next, in step S407, the display unit 301 of the client terminal 100 displays the Web page information received in step S404 on the Web browser. An example displayed on the Web browser will be described with reference to FIG.

  FIG. 9 is a schematic diagram showing an example of a user information registration screen according to the embodiment of the present invention.

  FIG. 9 is an example showing a display example in the case of HTML similar to 810 in FIG. 8, and 900 is an initial display state as it is with the Web page information received from the Web application 310 in step S404. User information is registered in the field 901.

  In step S407, after the display unit 301 of the client terminal 100 displays the Web page information on the Web browser, the user inputs data to the registration item of the Web page information. A screen image of the Web browser after data is input will be described with reference to FIG.

  910 of FIG. 9 is a schematic diagram showing a screen image after the user inputs 900 web page information.

  In 910, 911 displays data input by the user.

  When the user does not press the [Register] button 914 and presses the screen transition button 912 or the forced end button 913 in the state of the screen of 910, the screen shifts without the data input to the user 911 being registered in the Web application. As a result, the data 911 input by the user may be erased. At that time, the user has to input the URL of 900 again and input the data input in 911 again. In order to prevent the troublesome processing of the user, processing for displaying a warning screen (confirmation screen) to the user before the screen shifts will be described with reference to the flowchart of FIG.

  FIG. 5 is a flowchart showing an example of the second control processing unit in the client terminal 100 according to the embodiment of the present invention. The CPU 201 of each device stores the application program stored in the external memory 211 of each device. Realized by loading and executing on top. Note that S501 to S508 in the figure indicate processing steps.

  The flowchart in FIG. 5 is a flow of processing that is started when the screen transition button 912 or the forced end button 913 is pressed before the [Register] button 914 is pressed by the user.

  In step S501, the Web browser of the client terminal 100 detects that the screen transition button 912 or the forced end button 913 has been pressed. That is, it is a process of accepting a screen transition command without registering data in the Web application 310.

  Next, in step S502, the determination unit 303 of the client terminal 100 determines whether there is a registration item to be registered in the Web application 310 in the Web page information to be shifted to the screen, similarly to the processing determined in step S405.

  If it is determined that there is no registration item to be registered in the Web application 310 in the Web page information, it is not necessary to store the content input by the user, or it can be determined that there is no user input item, and the process proceeds to step S508. And execute screen transition processing and forced termination processing.

  On the other hand, if it is determined that there is a registration item to be registered in the web application 310 in the web page information, the process proceeds to step S503.

  When the process proceeds to step S503, the difference detection unit 305 of the client terminal 100 reads the initial value of the registration item in the Web page information to be shifted to the screen, which is stored in step S406. In the case of FIG. 9, referring to 900, nothing is input as the initial value of each item, that is, the parameter values in FIG. 7 are blank.

  Next, in step S504, the difference detection unit 305 of the client terminal 100 acquires an input value of a registration item at the time of screen transition of Web page information to be screen transitioned. In the case of FIG. 9, referring to 910, in the data structure of FIG. 7, the element value is “last name”, that is, the parameter name is “lastName”. The parameter value “Taro” or the like is acquired for the item “name”, that is, the parameter name “firstName”.

  Next, in step S505, the difference detection unit 305 of the client terminal 100 inputs the initial value of the registration item of the web page information read in step S503 and the registration item at the time of screen transition of the web page information acquired in step S504. Compare the value.

  If the initial value read in step S503 matches the input value acquired in step S504, it is determined that the user has not input data in the registration item, and the process proceeds to step S508, and the screen transition Execute processing and forced termination processing.

  On the other hand, if the initial value read in step S503 is different from the input value acquired in step S504, it is determined that there is a registration item input by the user, and the process proceeds to step S506.

  When the process proceeds to step S506, the screen transition confirming unit 306 of the client terminal 100 has a registration item input by the user, and therefore a confirmation screen (warning screen) as to whether the user can transition the screen without saving the input value. ) Is displayed. A display example of the confirmation screen will be described with reference to FIG.

  FIG. 10 is a schematic diagram showing a confirmation screen image at the time of screen transition of an unsaved screen according to the embodiment of the present invention.

  10 in FIG. 10 is an image diagram showing a dialog box 1001 displayed after the screen transition button 1004 or the forced end button 1005 is pressed on the user information registration screen.

  In the dialog box 1001, an “OK” button 1002 and a “Cancel” button 1003 are displayed at the same time as the message “There are unsaved contents. Do you want to execute the operation?”.

  When the [Cancel] button 1003 is pressed in the dialog box 1001, the screen transition process and the forced end process due to the screen transition button 1004 and the forced end button 1005 being pressed are stopped, and a series of processes are completed. 9 is returned to the input screen 910 (in the case of cancellation in step S506).

  On the other hand, when the [OK] button 1002 is pressed in the dialog box 1001, the process proceeds to step S507 in order to continue the screen transition process or the forced termination process.

  Next, in step S507, the input value storage unit 307 of the client terminal 100 stores the input value (parameter value) of the registered item in the Web page information to be transferred to the screen together with the parameter name (attribute value of the name attribute) and URL in the RAM 203 or Store in the external memory 211. An example of data stored in the input value storage unit 307 will be described with reference to FIG.

  Reference numerals 710 and 711 in FIG. 7 are diagrams illustrating examples of data when Web page information having the input value 910 in FIG. 9 is stored. The URL is stored in the first line of 710 and corresponds to the processing sequence NO in the second line. The parameter name and parameter value of the URL registration item associated with the processing sequence NO are stored as 711. The parameter values of these registration items are the input values acquired in step S504. Returning to the flowchart of FIG.

  Next, in step S508, a screen transition process or a forced end process corresponding to the screen transition button 1004 or the forced end button 1005 is executed. By this processing, the Web page information displaying the input value input by the user is lost from the Web browser.

  As a result of the above processing, when the input value to be registered in the Web application 310 input by the user disappears, that is, when the user changes the value of the registration item, the screen transition processing and the forced termination processing are executed. In this case, by displaying a warning screen (confirmation screen), it is possible to prevent the input value input by the user from being erased by an incorrect operation by urging the user to warn the user of the warning of the loss of the input value.

  Also, in the case of input items that do not need to be stored in the Web application, such as search keywords, among the input items of Web page information, the troublesome operation of the user is reduced by not displaying the warning screen (confirmation screen). It becomes possible.

  Next, the flow of processing for restoring the input value information of the Web page information in which the input value disappears will be described with reference to FIG.

  FIG. 6 is a flowchart illustrating an example of the third control processing unit in the information processing system according to the embodiment of this invention, and S601 to S608 in the figure indicate each step. The processing of each step is realized by the CPU 201 of each device loading and executing an application program stored in the external memory 211 of each device on the RAM 203.

  The flowchart of FIG. 6 is a flow of processing that is started when the client terminal 100 inputs the URL of the Web page information whose input value has been lost to the Web browser.

  First, in step S601, the receiving unit 302 of the client terminal 100 sends a request to the Web server specified by the URL or link input by the user.

  In step S602, when the web application 310 of the web application server 110 receives the request, in step S603, the web application 310 transmits the requested URL file to the client terminal 100.

  Next, in step S <b> 604, the receiving unit 302 of the client terminal 100 receives the web page information transmitted from the web application server 110.

  Next, in step S605, the display unit 301 of the client terminal 100 displays the Web page information received in step S604 on the Web browser. For example, 900 in FIG. 9 corresponds to the display image on the Web browser in step S605. In addition, when displaying the web page information of step S605 on a web browser, the process of step S405-S407 may be implemented.

  In step S <b> 606, the registration item input unit 308 of the client terminal 100 determines whether the currently displayed Web page information is the same as the Web page information stored in the input value storage unit 307.

  Specifically, the determination can be made based on whether the URL input in step S601 is equal to the URL stored in the input value storage unit 307. If the URL input in step S601 is not equal to the URL stored in the input value storage unit 307, the series of processing of the present invention is finished, and the process proceeds to processing of Web page information.

  On the other hand, when the URL input in step S601 is the same as the URL stored in the input value storage unit 307, a confirmation screen for displaying the input value stored in the input value storage unit 307 is displayed. The process proceeds to (S607).

  In step S <b> 607, the input value confirmation unit 309 of the client terminal 100 displays a screen for confirming to the user whether to reflect the input value stored in the input value storage unit 307 in the currently displayed web page information. . An image in which a confirmation screen is displayed to the user will be described with reference to FIG.

  FIG. 11 is a schematic diagram showing an image displaying a confirmation dialog box screen as to whether or not to restore the input value according to the embodiment of the present invention.

  11 is the same web page information as 900 in FIG. 9, and is an example in the case where input values such as 710 and 711 in FIG. 7 are stored. When the URL of the Web page information is the same as that of the input value storage unit 307, a dialog box such as 1101 is displayed, and a selection button for reflecting the input value input and stored in the past is displayed.

  When a [Cancel] button 1103 is pressed in 1101, a series of processes of the present invention is finished and the process proceeds to Web page information processing.

  On the other hand, when the [OK] button 1102 is pressed in 1101, the process proceeds to processing for reflecting the input value stored in the input value storage unit 307 (step S608).
