I would like to insert a parameter value found the url into my javascript code.. So basically i have the following url www.rene-zamm.com/mp-dthanks.asp?gglid=1231开发者_Python百科23123

Now i have the following javascript code in the same page and i want that number in the url to be visible also in the javascript code below:

var gwoTracker=_gat._getTracker("UA-1639156-3");
gwoTracker._trackPageview("/**NUMBER OF URL HERE**/goal");

Can someone help me please?

You need to parse the querystring. Javascript has no inbuilt way of doing this easily, but there are some nice functions you can use:

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

Then in your example you could do:

var queryData = gup("gglid");
var gwoTracker=_gat._getTracker("UA-1639156-3"); gwoTracker._trackPageview("/" + queryData  + "/goal");
