Two ways to get URL parameters for JS

JS get parameters, in the past I was used to split, and then get, this way feeling is the simplest

Mode 1:

function QueryString (item) {    var svalue=location.search.match (new RegExp ("[\?\&]" +item+ "= ([^\&]*) (\&?)", "I"))    return svalue?svalue[1]:svalue}//  Use method //url=http://www.xxx.com?id=100&name=domvar id=querystring ("ID" );   var name=querystring ("name");

In this way, every time you call QueryString () This method will parse the URL once (of course, many parameters of the case will not be slow to parse)

Mode 2:

           functiongetrequest () {varurl = location.search;//gets the URL in the "?" String after the character                  varTherequest =NewObject ();//put parameters into this object                 if(Url.indexof ("?")! =-1) {                   varstr = URL.SUBSTR (1); STRs= Str.split ("&"); //Storage Parameters                     for(vari = 0; i < strs.length; i + +) {Therequest[strs[i].split ("=") [0]]= (Strs[i].split ("=") [1]); }                  }                  returntherequest; }//How to use                varRequest =NewObject (); Request=getrequest (); //url--http:www.xxx.com?id=1&&kid=2                 varid=requesr["id"];

This way the parameters are stored in one object at a time, and the URL is parsed again when the argument is taken.
