Self-adaptive typesetting and refreshing method and device for data visualization large-screen display page

Abstract

The invention discloses a self-adaptive typesetting and refreshing device for a data visualization large-screen display page, and relates to the technical field of information. According to the method, the page display elements are self-adaptive to the size of the visual interval of the browser. A page refreshing mode is adopted as a triggering mode of retypesetting. Through information collectedby a browser type detector, a browser state detector, and a large-screen parameter detector, the state of the browser is determined. Different page refreshing modes are adopted according to differentstates of the browser, the refreshing frequency of the page is effectively controlled, and the phenomenon that large-screen display information is lost or user input information is lost due to browserstate switching is completely eradicated.

Description

technical field [0001] The present invention relates to the field of information technology, especially the field of software development. Background technique [0002] An important branch of the data visualization page is a page specially displayed on some professional equipment, which is called a large-screen display page in the industry, or a large-screen page for short. The environment for displaying such large-screen pages is often a high-definition projector, or an LED screen, or a giant screen environment similar to a theater. [0003] This kind of large-screen page has its own unique characteristics in design and development, and these characteristics are summarized as follows: [0004] Relevant definitions: The browser's viewable area is the area where the browser displays content, and the viewable area does not include elements such as the browser's address bar, toolbar, and scroll bar. [0005] Feature 1: The browser displays a large-screen page, and the content...

Problems solved by technology

[0016] Solution 2 is easy to operate, and the code is easy to reuse in different large-screen pages, so it is a more common and general adaptive solution for display elements than Solution 1, but there is a problem with this solution, that is, the browser only needs to visualize the Any change in the size of the interval will cause the page to refresh, which leads to the following problems:

[0017] Question 1: If there are certain operation steps on the big screen page, if the page operation steps have not been completed, if the page self-adaptive function is triggered at this time and the page automatically refreshes, this will invalidate the previous operation steps

[0018] Question 2: The data displayed on the large-screen page often needs to request the corresponding server, so it takes a certain amount of time to fully load the page when the page is initialized. If the page request response time is too long, this will affect the user experience of the page, thus Affects the final display effect of the page, so appropriately reducing the overall refresh of the page during the presentation is an important means to ensure the quality of the presentation

Of course, some browsers have a way to judge whether the browser is full-screen or not, but this method is not a function implemented by all different browsers nowadays, so browser compatibility issues cannot be achieved
