Page element real-time highlighted display method and apparatus

Abstract

The application discloses a page element real-time highlighted display method and apparatus. The method comprises: creating a window object; displaying the window object above a browser main body interface in a manner of overlay display, and performing memory copy on the content displayed in a window of the browser main body interface to copy the content into the window object; obtaining the position and an occupied display region of each page element displayed in the window of the main body interface, in the window; obtaining the position of a mouse pointer in the window; according to the obtained position of the mouse pointer as well as position and occupied display region of each page element in the window, determining whether an event of moving the mouse pointer to a target page element occurs or not; and if so, determining a display region whether the target page element is as a target display region, and performing highlighted display on the target display region in a preset rendering mode in the window object. With the method, the highlighted display timeliness and adaptability of page elements are improved.

Description

technical field [0001] The present application relates to the field of computer application technology, in particular to a method and device for highlighting page elements in real time. Background technique [0002] People usually use browser software to browse information on the Internet, and the browsers are used to browse various webpages provided by service providers. Regardless of the design of browser software or the writing of web page codes, a basic starting point is to facilitate the use of users. For example, when the user moves the mouse over an element, if the element is a hyperlink, a line will automatically appear below the link, and the shape of the mouse pointer will change to indicate that the element can be clicked. etc. [0003] In addition, some application programs appear in the prior art, which can provide users with richer functions based on the functions of the browser or web page codes. For example, when a user browses a web page, when the mouse m...

Problems solved by technology

However, when using double buffering technology to achieve page drawing, the browser will send a notification to the application program after drawing the data to the memory object, and the actual redrawing may not be completed on the display device at this time , In this way, if the browser dynamically highlights the page elements on the mouse track, after the data is drawn to the memory object, the browser sends a notification of the completion of the drawing, instructing the application to continue the operation, and the data to be drawn at this time is updated It still takes a certain amount of time to reach the display device, and the display device still displays the highlighted state of the previous page element. At the same time, after receiving the notification that the browser has finished drawing, the browser will perform the highlighting on the current page element. display, which causes multiple highlighted page elements to appear simultaneously on the track of the mouse sliding, which is contrary to the original intention of dynamically highlighting the page elements on the mouse track

[0006] In order to solve this contradiction, the existing technology adopts a method of delaying after drawing. Specifically, after the browser notifies that the drawing is completed, a certain delay operation is performed to wait for the data object to be drawn to be transferred from the memory to the display device. After the copy is completed, the current page elements will be highlighted. However, this method of delay after drawing is relatively mechanical, and the short delay time cannot adapt to operations with a large amount of data and computers with low performance. Longer delays will result in less real-time dynamic highlighting of page elements on the mouse track
