A recent project encountered such a problem:

There is a DIV block with a scroll bar for displaying data. The business requirement is to read and display the data in the database when the scroll bar is rolling. This is not a problem in itself, but in reality it is found that when the data volume is large, when the scroll bar is rolling, it will not stop sending data requests to the background, this puts huge pressure on servers and browsers when the traffic volume reaches a certain scale.

To solve this problem, the author thought of a way to send request data to the server only when the scroll bar is stopped. But how can I determine whether the scroll bar is stopped? After several studies, I finally solved the problem. Here I will share with you how to use js to determine whether the browser's scroll bar stops rolling (the effect here is compatible with IE and Firefox browsers ).

<Html xmlns = "http://www.phpernote.com/javascript-function/194.html"> 

The above can change the time for regular judgment. The shorter the time, the more timely the corresponding time, the better the user experience, but the pressure on the corresponding client browser will increase.
