 parseQueryString: function (url) {
  var reg_url = /^[^\?]+\?([\w\W]+)$/,
   reg_para = /([^&=]+)=([\w\W]*?)(&|$|#)/g,
   arr_url = reg_url.exec(url),
   ret = {};
  if (arr_url && arr_url[1]) {
   var str_para = arr_url[1], result;
   while ((result = reg_para.exec(str_para)) != null) {
    ret[result[1]] = result[2];
   }
  }
  return ret;
 }

// 通過key獲取url中的參數(shù)值

 getQueryString: function (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;
 }

示例二：

js通過兩種方法獲取url傳遞參數(shù)：

js獲取url傳遞參數(shù)方法一：

這里是一個獲取URL帶QUESTRING參數(shù)的JAVASCRIPT客戶端解決方案，相當(dāng)于asp的request.querystring，PHP的$_GET
函數(shù):

<Script language="javascript">
function GetRequest() {
 
 var url = location.search; //獲取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]]=(strs[i].split("=")[1]);
  }
 }
 return theRequest;
}
</Script>

然后我們通過調(diào)用此函數(shù)獲取對應(yīng)參數(shù)值：

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

以此獲取url串中所帶的同名參數(shù)

js獲取url傳遞參數(shù)方法二正則分析法：

function GetQueryString(name) {
  var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)","i");
  var r = window.location.search.substr(1).match(reg);
  if (r!=null) return (r[2]); return null;
}
alert(GetQueryString("參數(shù)名1"));
alert(GetQueryString("參數(shù)名2"));
alert(GetQueryString("參數(shù)名3"));
