JavaScript gets the parameters in Url

Recently developed projects need to use JavaScript to read the values of parameters in the Url string

Through the search for information and their own experiments, finally succeeded

The script is as follows:

<script type="text/javascript">

      function GetRequest(strName)

     {

           var strHref = window.location.href; // To obtain Url string 

           var intPos = strHref.indexOf("?");  //  Parameter starting position 

           var strRight = strHref.substr(intPos + 1);

           var arrTmp = strRight.split("&"); // Parameter separator 

           for(var i = 0; i < arrTmp.length; i++) 

           { 

                 var arrTemp = arrTmp[i].split("="); 

                 if(arrTemp[0].toUpperCase() == strName.toUpperCase()) return arrTemp[1]; 

           } 

           return ""; 

      }

</script>

Testing:

<script>

      var id=GetRequest("ID") ;

     alert(id);

</script>
