JS get url parameter value: JS get url parameter

<script language= "JavaScript" >
function Getrequest () {
var url = location.search; Get the "?" in the URL 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]]=unescape (Strs[i].split ("=") [1]);
}
}
return therequest;
}
</script>
Then we get the corresponding parameter values by calling this function:
<script language= "JavaScript" >
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 '];
</script>
To get the parameter with the same name that is 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 unescape (r[2]); return null;
}
Alert (getquerystring ("parameter name 1"));
Alert (getquerystring ("parameter Name 2"));
Alert (getquerystring ("parameter name 3")); This article links http://www.cxybl.com/html/wyzz/JavaScript_Ajax/20120708/31778.html
