js擷取url參數值

標籤：c   style   class   blog   code   java   

方法一：正則分析法

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;}

這樣調用：

alert(GetQueryString("參數名1"));alert(GetQueryString("參數名2"));alert(GetQueryString("參數名3"));

方法二：

<span style="font-size: 16px;"><Script language="javascript">function GetRequest() {   var url = location.search; //擷取url中"?"符後的字串   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></span>

這樣調用：

<Script language="javascript">var Request = new Object();Request = GetRequest();var 參數1,參數2,參數3,參數N;參數1 = Request[‘參數1‘];參數2 = Request[‘參數2‘];參數3 = Request[‘參數3‘];參數N = Request[‘參數N‘];</Script>
