js 获取url参数

在网上找到了两个很又简单实用的方法,mark下

方法一:正则分析法

 

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]); returnnull;
}

这样调用:

alert(GetQueryString("参数名1"));

alert(GetQueryString(
"参数名2"));

alert(GetQueryString(
"参数名3"));

方法二:

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

这样调用:

复制代码
<Script language="javascript">
var Request =new Object();
Request
= GetRequest();
var 参数1,参数2,参数3,参数N;
参数1
= Request['参数1'];
参数2
= Request['参数2'];
参数3
= Request['参数3'];
参数N
= Request['参数N'];
</Script>
复制代码
