The method used by javascript to query string parameters. It is a javascript string.

This example describes how to query string parameters in javascript. Share it with you for your reference. The specific implementation method is as follows:

Copy codeThe Code is as follows:/* parse the query string and return an object containing all parameters */

Function getQueryStringArgs (){

// Obtain the query string and remove the question mark at the beginning
Var qs = (location. search. length> 0? Location. search. substring (1 ):'');

// The object that saves the data
Args = {};

// Obtain each item
Var items = qs. length? Qs. split ('&'): [],
Item = null,
Name = null,
// Used in the for Loop
I = 0, len = items. length;

// Add each item to The args object one by one
For (I = 0; I <len; I ++ ){
Item = items [I]. split ('= ');
Name = decodeURIComponent (item [0]);
Value = decodeURIComponent (item [1]);

If (name. length ){
Args [name] = value;
}
}
Return args;
}

In this way, you can easily obtain the corresponding parameter values in the URL.
