The invention uses a mark-up language definition for the display page that needs to be adjusted, and stores the display page that needs to be adjusted as a label language file, receives a zoom instruction of the user, and modifies the corresponding label language file according to the zoom instruction. The modified file is displayed to the user through the terminal browser.

 The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

 Referring to FIG. 1 , a method for implementing a terminal browser-based zoom display page of the present invention includes:

 Step 101: The display page that needs to be adjusted is defined and stored as a label language file by using a label language, and the display page that needs to be adjusted is displayed by the browser;

 A display page with fixed content and format (such as a function menu) is defined by using a tag language, and the defined display page is stored in the terminal as a tag language file, and is read by the browser when browsing the display page. The corresponding file is presented to the user.

 Step 102: Receive a zoom instruction issued by the user to the displayed display page of the browsing;

 After the display page is displayed to the user through the browser, the user can zoom in on the currently displayed page by using a button or a menu; of course, it is necessary to preset different display buttons or menu corresponding display element attributes on the terminal, and the display element includes text. The image attribute includes the position, size, background, color, and the like of the element, so that the currently displayed page can be zoomed by a button or a menu.

 Step 103: Modify a corresponding label language file according to the scaling instruction, and display the modified label language file as a scaled display page by using a browser;

The corresponding label language file is modified according to the corresponding display element attribute selected by the user through a button or a menu, and the modified file is displayed to the user through the terminal browser. In a preferred embodiment of the present invention, the method further includes: when the display element attribute input by the user exceeds the support range of the terminal, the terminal sends a prompt tone to notify that the limit of the zoom display has been reached.

 Referring to Fig. 2, there is shown a schematic diagram of a device structure of a browser-based zoom display page of the present invention. The device for zooming and displaying a page includes: a processing unit 201, a receiving unit 202, and a zoom display unit 203;

 The processing unit 201 is configured to use a label language definition for the display page that needs to be adjusted, and store the display page that needs to be adjusted as a label language file, and display the display page that needs to be adjusted through the browser;

 The receiving unit 202 is configured to receive a zoom instruction issued by the user to the browsed display page, and the zoom display unit 203 is configured to modify the corresponding label language file according to the zoom instruction, and display the modified label language file as a browser through the browser. The displayed page after scaling.

 In a preferred embodiment of the present invention, the method further includes:

 The preset unit 200 is configured to preset different display buttons or menu corresponding display element attributes on the terminal;

 Correspondingly, the receiving unit 202 is configured to receive a zoom instruction of a change display element attribute that is sent by the user to the current display page by using a button or a menu.

 The display element includes text, an image, and the element attribute includes one or more of an element's position, size, background, and color.

 In a preferred embodiment of the present invention, the zoom display unit 203 is further configured to modify the corresponding tag language file according to a corresponding display element attribute selected by the user through a button or a menu.

It is to be noted that, in order to implement the functions of the present invention, the browser of the present invention includes: a transceiver module, configured to receive a label language file delivered by a website when browsing a webpage; and a parsing module, configured to receive the transceiver module The data in the tag language file is solved Analysis processing

 a layout module, configured to process the parsed data, and determine a location of the various page information described by the data on the terminal interface;

 a drawing module for displaying the parsed and laid out page information;

 The memory management module is used to save the displayed page information for use when opening each interface again.

 Through the above steps and devices, the zoom display of the terminal page can be realized. Since menu files and CSS (Cascading Style Sheets) files are stored locally and the content is relatively simple, using a browser to open the page and zooming is fast.

 The invention is further illustrated by the following examples in specific applications.

 In the following, a message menu interface is combined with a mobile phone browser as an example to describe a specific implementation method for zooming and displaying a page, including the following steps:

 (1) definition of the mobile phone menu interface;

 Use the label language to accurately describe the display of text, image position, size, background, color, and more. Let's take a menu of a common message module as an example to illustrate how to use html (Hypertext Markup Language).

 The corresponding definition of the message menu is as follows:

 <HTML>

 <HEAD>

 <TITLE> Messaging </TITLE>

 <LINK REL=stylesheet HREF="styles.css" type="text/css">

 </HEAD>

 <BODY>

 <p><img src="01.png" /><a hrel^"l.htmr> ^Build a message </a></p>

 <p><img src="02.png" /><a hre^"2.htmM : Box </a></p>

<p><img src="03.png"/><ahrel^"3.htmr>DraftBox</a></p> <p><img src="04.png"/><ahre^"4.html">Disappeared,</a></p><p><imgsrc="05.png"/><ahrel^"5.htmr> Information Template</a></p>

 </BODY>

 </HTML>

 The above menu files and styles.css files are stored in a fixed location on the phone. Among them, styles.css is an out-of-line ess file, which can control the display style of the menu. The zoom control of the present invention is also completed by this file. See Figure 3 for the effects displayed in the mobile browser.

 (2) processing a zoom instruction input by the user;

 The user can zoom by pressing a button (such as the up/down direction keys or the up and down keys on the side of the phone) or menu. When the mobile phone receives the zoom-in and zoom-out command input by the user, it will modify the attribute value corresponding to the font and image size in the styles.css file described in (1) according to the input command. The font size attribute is defined as follows:

 Body { font-size: medium; }

 The value of font-size includes:

 Xx-small/ x-small/ small/ medium/ large/ x-large/ xx-large

 The fonts corresponding to the above attribute values are incremented from small to large, where medium corresponds to the default font size of the terminal.

 The image scaling is defined as follows:

 Img {width="100%" height="100%"}

 Where width and height are the width and height of the image, and a value of 100% means that it is displayed according to the size of the image itself.

 When the zoom-in and multiplier input by the user exceeds the support range of the mobile phone, the mobile phone will give a prompt to inform the user that the limit of the zoom display has been reached.

 (3) The mobile browser displays a menu page;

The display of the menu interface is the same as that of the general web page. When a menu is opened, the browser will Read the corresponding file from the file system and display it for processing.

 Other uses of the present invention are: The zoom function of the page is also suitable for browsing web pages, short messages, notepads, and the like. In addition, the browser can also be used as a text reader. For the read file, it is first converted into a tag language file, and then opened by the browser, so that the user can adjust the text size at will while reading.

 In the meantime, it is to be noted that the foregoing is only a specific embodiment of the present invention, and those skilled in the art can change and modify the present invention, and the modifications and variations are within the scope of the claims and the equivalents thereof. All should be considered as the scope of protection of the present invention.
