Get the Get parameter method with JS on HTML page

Here is a JavaScript client solution that gets the URL with the questring parameter, equivalent to the ASP's request.querystring,php $_get

Function:

function Getrequest () {

var url = location.search; Gets the URL in the "?" String after the character

var therequest = new Object ();

if (Url.indexof ("?")! =-1) {

var str = URL.SUBSTR (1);

STRs = Str.split ("&");

for (var i = 0; i < strs.length; i + +) {

Therequest[strs[i].split ("=") [0]]= (Strs[i].split ("=") [1]);

}

}

return therequest;

}

Then we get the corresponding parameter value by calling this function:

var Request = new Object ();

Request = Getrequest ();

var parameter 1, Parameter 2, parameter 3, parameter n;

Parameter 1 = request[' parameter 1 '];

Parameter 2 = request[' parameter 2 '];

Parameter 3 = request[' parameter 3 '];

Parameter n = request[' parameter n '];

This gets the parameter with the same name in the URL string

Second, the regular analysis method.

function getquerystring (name) {

var reg = new RegExp ("(^|&)" + name + "= ([^&]*) (&|$)", "I");

var r = window.location.search.substr (1). Match (REG);

if (r!=null) return (r[2]); return null;

}

Alert (getquerystring ("parameter name 1"));

Alert (getquerystring ("parameter Name 2"));

Alert (getquerystring ("parameter name 3"));
