Using ajax to load the progress bar in the web page allows the user to judge the waiting time in advance, and can also reduce the user's psychological anxiety while waiting for the information to be loaded. Therefore, the progress bar is essential for loading. Here is what I will tell you Introducing how the ajax loading progress bar code is implemented

The final effect is shown in the figure below. It can be displayed on both PC and mobile terminals. The calling method is also very simple. Start calling: loading.baosight.showPageLoadingMsg(false), alse represents unrealistic loading instructions, and true displays loading instructions. After the call is completed, call: loading.baosight.hidePageLoadingMsg(). There are two files in the entire code, one is a js file and the other is a css file. Remember not to forget to introduce jquery.js
