Detailed jquery get URL parameter description

Your current URL is:
http://www.xxx.com/index.php tutorial? test=1&kk=2

If you want to get test, you can introduce the plug-in,
Get it in the following ways:
var test = $.query.get (' test ');

If the parameter has multiple identical names, you can do this:
var arr = $.query.get (' testy ');
Output: [value 1, Value 2, value 3 ...]

If you want to get more than one of the same names, you can do this:
var arrayelement = $.query.get (' testy[1] ');

This plug-in can not only get parameters, but also set parameters.

Set a parameter:
var newurl = $.query.set ("section", 5). ToString ();
Output: "? section=5"

Set two parameters:
var newurl = $.query.set ("section", 5). Set (' Action ', ' do '). ToString ();
Output: "? action=do&section=5"

To delete a parameter:
var oldqueryagain = $.query.remove ("type");

Clear All Parameters:
var emptyquery = $.query.empty ();

Copy all parameters:
var stillthesame = $.query.copy ();
