JS get URL parameter value

Method One: The regular analysis method

function getquerystring (name) {    varnew RegExp ("(^|&)" + name + "= ([^&]*) (&|$)", "I" );     var r = window.location.search.substr (1). Match (reg);     if NULL return return NULL ;}

This is called:

Alert (getquerystring ("parameter name 1")),alert (getquerystring ("parameter Name 2"), alert (getquerystring ("parameter name 3"));

Method Two:

<spanstyle= "FONT-SIZE:16PX;"><Scriptlanguage= "JavaScript">functiongetrequest () {varURL=Location.search;//gets the URL in the "?" String after the character   vartherequest= NewObject (); if(Url.indexof ("?") != -1) {      varStr=Url.substr (1); STRs=Str.split ("&");  for(varI= 0; I<strs.length; I++) {Therequest[strs[i].split ("=")[0]]=unescape (Strs[i].split ("=")[1]); }   }   returntherequest;}</Script></span>

This is called:

<script language= "JavaScript" >varnew= getrequest (); var  = request[' parameter 1 '= request[' parameter 2 '= request[' parameter 3 '= request[' parameter n ']; </Script>
