How to sort js headers and js Headers

This article describes how to sort js headers. Share it with you for your reference.

The specific implementation method is as follows:

Copy codeThe Code is as follows:
<Script type = "text/javascript">
// Whether to decrease the order
Var isDescending = true;
/*************************************** **
* The row to be sorted must be placed in the <tbody> </tbody> label.
* TableId: the ID of the sorting table.
* ColNo: Number of the column to be sorted, that is, the column number, starting from 0.
* StartRowNo: the starting line number of the sorting, starting from 0.
* SortLength: number of rows to be sorted,
* Type: the type of the sort column.
