try this:

var tmp = location.href, it;
if (q) it = tmp.substr(q + 1).split('&');
else it = '';
for (var i in it) {
    var t = it[i].split('=');
    if (t[0] == 'p') {
        //do something
        break;
    }
}

function _GET( 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];
}

This will do the equivalent in javascript.
