Then, the web browser displays only the web page displayed in the child frame. Therefore, if the web page that is displayed in the child frame does not exist as a web page, or if you do not want to display only the web page that is displayed in the child frame alone, you can use only the web page in the child frame. Could not be prohibited.

  The object of the present invention is to use a child frame web page alone when the child frame web page alone does not constitute a web page or when it is not desired to display only the child frame web page alone. It is an object of the present invention to provide a method for displaying a web page that can prohibit the display of.

  In order to achieve the above object, a method for displaying a web page according to claim 1, wherein the web page is displayed after being divided into a parent frame and one or more child frames using a frame. A determination step for determining whether or not the parent frame exists, and a web page display prohibiting step for prohibiting display of all the web pages of the child frame when the parent frame does not exist. Features.

  The web page display method according to claim 2 is the web page display method according to claim 1, wherein the determination step determines whether one of the child frames is present, and the web page display prohibition step. When one of the child frames does not exist, display of another web page of the child frame is prohibited.

  In order to achieve the above object, the program according to claim 3 executes, on a computer, a web page display method for displaying a web page after dividing the web page into a parent frame and one or more child frames using frames. A determination module that determines whether or not the parent frame exists, and a web page display prohibition module that prohibits display of all web pages of the child frame when the parent frame does not exist. It is characterized by that.

  To achieve the above object, a storage medium according to claim 4 stores the program according to claim 3.

  According to the web page display method according to claim 1, the program according to claim 3, and the storage medium according to claim 4, the web page is divided into a parent frame and one or more child frames using frames. When the parent frame does not exist, the child frame web page is prohibited from being displayed, so if the child frame web page alone does not exist as a web page, or only the child frame web page is simply displayed. If you do not want to display a single frame, you can prohibit the display of only the child frame web page.

  According to the web page display method of claim 2, when one of the child frames does not exist, display of the other one web page of the child frame is prohibited, so that only the web page of the child frame is used alone. The display can be definitely prohibited.

  FIG. 4 is a flowchart showing print service processing executed by the print service system of FIG.

  The process of FIG. 4 is to access the print service server 101 from the user terminal 100 and print it out.

  When a login request process from the user terminal 100 to the print service server 101 is performed (step S601), an authentication process is performed in the print service server 101 (step S602), and the result of access permission / denial is notified.

  When a search request for a document registered in advance in the print service server 101 is made (step S603), the requested document search process is performed on the print service server 101 side (step S604), and the result is notified.

When a preview display request for a specific page of the document is made (step S605), a preview image of the designated page of the document is created, and information such as the image and page number is notified (step S606). For preview, a plurality of sheets can be displayed on the same screen. The image size to be created is adjusted to the optimum size according to the number of display sheets.
When the screen shifts to the printer selection screen (step S607), all printers connected to the print service server 101 are searched, and the acquired printer list is notified to the user terminal 100 (step S608). When the user selects a printer from the list, the server is notified of the printer name and temporarily stored in the document.

  When the screen shifts to the print format setting request screen (step S609), the user is notified of information that can be set for the printer, and if the user sets the printer information, the information updates the print format setting information of the temporary document on the server. (Step S610).

  When a save request is made (step S611), the temporary document is saved (step S612).

  When an editing request is made (step S613), the editing information is notified to the user terminal 100, and the result of the editing performed by the user according to the information is stored in the temporary document on the server (step S614).

  When a print request is made (step S615), the temporary document is accepted for printing (step S616). The accepted document is temporarily stored here, and when the printer is not busy, the printing process is performed by the printer 110. Output (step S618).

  The screens of steps S605, S607, S609, S611, S613, and S615 of the user terminal 100 are not shifted sequentially, but can be appropriately selected by the user at random.

  The print service system of FIGS. 1 and 2 divides a web page using frames, and displays the web page as a parent frame (FIG. 5) and one or more child frames (FIG. 6).

  The parent frame 50 in FIG. 5 is composed of three child frames 61, 62, 63 as shown in FIG. Note that the parent frame 50 sets the arrangement information of the child frames 61, 62, and 63, and therefore does not appear on the UI. The parent frame 50 designates the URL of the web page to be displayed on the child frames 61, 62, 63. Since the web server 102 only sends page data corresponding to the URL received from the user terminal 100 to the user terminal 100, the web server 102 recognizes whether the destination of the page data is an ordinary web page or a frame type web page. Absent. Therefore, when the page data of the web page to be displayed on the child frames 61, 62, 63 is loaded into the web browser, the web browser performs the web page display process of FIG. Then, even if the URL of the web page to be displayed in the child frames 61, 62, 63 is directly input to the web browser, the web browser executes the web page display process of FIG. The page data can be determined not to be displayed as the web page of the child frames 61, 62, 63, and the web browser can display the error screen of FIG. 9 (FIG. 8).

  FIG. 7 is a flowchart of web page display processing according to the embodiment of the present invention, and shows a case where it is determined whether or not a parent frame exists.

  The HTML document as page data is received from the web server 102 (step S801), and the web browser uses the Java script (Java (registered trademark) Script) included in the HTML document received from the web server 102 to set the parent frame. It is determined whether or not 50 is loaded on the same web page (step S802).

  As a result of the determination in step S802, when the web page of the parent frame is loaded on the web browser (YES in step S802), the web browser displays the HTML document sent from the web server 102 as it is (step S803), When the web page of the frame 50 is not loaded on the web browser (NO in step S802), the web browser executes an error display process of FIG. 8 described later (step S804), and ends this process.

  According to the process of FIG. 7, when the web page of the parent frame 50 is not loaded in the web browser (NO in step S802), the web browser executes an error display process (step S804). Display on a single page can be prohibited.

  FIG. 8 is a flowchart of the error display process executed in step S804 of FIG.

  In FIG. 8, the web browser notifies the web server 102 as an error that the parent frame 50 is not loaded in the web browser in which the page data of the web page has been downloaded (step S901), and the web server 102 is a child. Based on the error information sent from the web browser displaying the web pages of the frames 61, 62, 63, the page data of the error screen is transmitted to the web browser of the user terminal 100. An error screen web page is displayed (step S902), and the process is terminated.

  According to the process of FIG. 8, since the web browser notifies the web server 102 of an error (step S901), the web server 102 can transmit the page data of the error screen to the web browser of the user terminal 100. An error screen can be displayed on the web browser of the user terminal 100.

  FIG. 10 is a flowchart of web page display processing according to the embodiment of the present invention, and shows a case where display of a web page of another child frame is prohibited when one of the child frames does not exist.

  In FIG. 10, an HTML document that is page data is received from the web server 102 (step S1001), and a web browser is used by using a Java script (Java (registered trademark)) included in the HTML document received from the web server. It is determined whether or not the web pages of the other child frames 61, 62, 63 are loaded (step S1002).

  If it is determined in step S1002 that the web pages of the other child frames 61, 62, and 63 have been loaded on the web browser (YES in step S1002), the web browser uses the HTML document sent from the web server 102 as it is. When the web page of the other child frames 61, 62, 63 is not loaded on the web browser (NO in step S1002), the web browser executes the error display process shown in FIG. (Step S804), and this process is terminated.

  According to the process of FIG. 10, when the web pages of the other child frames 61, 62, 63 are not loaded on the web browser (NO in step S1003), the web browser executes the error display process of FIG. Therefore (step S804), the display of the child frame alone on the web page can be surely prohibited.
