  Extracting variables from a url

  Feb 26, 2013 10:36 PM|LINK

  I have written a jQuery program and inserted it into my Page1.aspx file.

  js-url.js resides in the Scripts file in the base folder.

  I have a website coming into this page:
   
  http://www.mypage.com/Page1.aspx?var1=123&var2=987
   
  This jQuery code is suppose to extract the variables var1 and var2 from the url and place them into TextBox1 and TextBox2 respectively.

  I am not sure if js-url.js is the correct script.
   
  If someone knows a better or the same way to extract these variables please show me.

  <script src="../Scripts/js-url.js" type="text/javascript"></script>
          <script language="javascript" type="text/javascript">
              $(document).ready(function() {
                  var GET1=$("#TextBox1");
                  var GET2=$("#TextBox2");
                  GET1.val($.url("?var1"));
                  GET2.val($.url("?var2"));
              });
          </script>

  Do you need more functionality within the js-url.js file?  A jQuery plugin seems like overkill for this feature.  I found a reusable function in pure javascript that supposedly does the trick pretty well:

  http://stackoverflow.com/questions/901115/how-can-i-get-query-string-values

  function getParameterByName(name)
  {
    name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
    var regexS = "[\\?&]" + name + "=([^&#]*)";
    var regex = new RegExp(regexS);
    var results = regex.exec(window.location.search);
    if(results == null)
      return "";
    else
      return decodeURIComponent(results[1].replace(/\+/g, " "));
  }

  does this script work fine? if yes, then u can go ahead with it

  there are few more plugins to read querystring values... like this

  http://code.google.com/p/m-jq-projects/wiki/rwQueryString_jQuery

  which is just works and compact (not event a kb)...

  or, u can simply use a string manipulation technique to get the querystring

  function GetQueryStringValue (strKey) (
    var url = window.location.search;
    var querystringStr = url.substring(url.indexOf("?"));
    var keys = querystringStr.split('&');
    for(i=0 ; i< keys.length; i++) {
        var key = keys[i].split('=')[0];
        var value = keys[i].split('=')[1];
        if(strKey == key) {    
           return value
        }
    }
  }

  hope this helps...

  Cheers!

  Try as below,

  function GetQueryStringParams(sParam)
  {
      var sPageURL = window.location.search.substring(1);
      var sURLVariables = sPageURL.split('&');
      for (var i = 0; i < sURLVariables.length; i++) 
      {
          var sParameterName = sURLVariables[i].split('=');
          if (sParameterName[0] == sParam) 
          {
              return sParameterName[1];
          }
      }
  } 

  GET1.val(GetQueryStringParams('var1')); 

  GET2.val(GetQueryStringParams('var2'));

  Hi,

  You can use query string. The code as follow:

  string t=Request.QueryString["name"];

  More details, please refer to: http://msdn.microsoft.com/en-us/library/system.web.httprequest.querystring.aspx.

  string t=Request.QueryString["name"];

  I think he's looking for a Javascript solution.

  Hi,

  Yes, with javascript you can refer the follow code:

  var first = getUrlVars()["id"];
  var second = getUrlVars()["page"];
   
  alert(first);
  alert(second);

  function getUrlVars() {
      var vars = {};
      var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
          vars[key] = value;
      });
      return vars;
  }
