Sample code sharing of Get parameter method using JS in HTML page

Here is a JAVASCRIPT client solution for obtaining the URL with QUESTRING parameters, which is equivalent to asp's request.querystring, PHP's $_GET

here is A JAVASCRIPT client solution for obtaining URLs with QUESTRING parameters, which is equivalent to asp's request.querystring, PHP's $_GET

function:

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]]=(strs[i].split("=")[1]);
      }
   }
   return theRequest;
}

Then we call This function obtains the corresponding parameter value:

var Request = new Object();
Request = GetRequest();

var parameter 1, parameter 2, parameter 3, parameter N;

Parameter 1 = Request[''Parameter 1''];

Parameter 2 = Request[''Parameter 2''];

Parameter 3 = Request[''Parameter 3''];

Parameter N = Request[''Parameter N' '];

Use this to obtain the parameter with the same name in the url string

2. Regular analysis method.

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("参数名1"));
alert(GetQueryString("参数名2"));
alert(GetQueryString("参数名3"));
