/**
 * Equal Heights Plugin
 * Equalize the heights of elements. Great for columns or any elements
 * that need to be the same size (floats, etc).
 * 
 * Version 1.0
 * Updated 12/10/2008
 *
 * Copyright (c) 2008 Rob Glazebrook (cssnewbie.com) 
 *
 * Usage: $(object).equalHeights([minHeight], [maxHeight]);
 * 
 * Example 1: $(".cols").equalHeights(); Sets all columns to the same height.
 * Example 2: $(".cols").equalHeights(400); Sets all cols to at least 400px tall.
 * Example 3: $(".cols").equalHeights(100,300); Cols are at least 100 but no more
 * than 300 pixels tall. Elements with too much content will gain a scrollbar.
 * Oder falls ID statt Class: $(“#div1, #div2″).equalHeights();
 *

This plugin can be used to get the URL parameters. You have to specify, which parameter you want. If the parameter does not exist, you will get “null”.

 var param1 = $.getURLParam("userID");

Even testing, if a specific parameter exists, is easy:

if ($.getURLParam("userID")==null) {
  alert("There is no userID");
}

*/ 

getURLParam: function(strParamName){
	  var strReturn = "";
	  var strHref = window.location.href;
	  var bFound=false;
	  
	  var cmpstring = strParamName + "=";
	  var cmplen = cmpstring.length;

	  if ( strHref.indexOf("?") > -1 ){
	    var strQueryString = strHref.substr(strHref.indexOf("?")+1);
	    var aQueryString = strQueryString.split("&");
	    for ( var iParam = 0; iParam < aQueryString.length; iParam++ ){
	      if (aQueryString[iParam].substr(0,cmplen)==cmpstring){
	        var aParam = aQueryString[iParam].split("=");
	        strReturn = aParam[1];
	        bFound=true;
	        break;
	      }
	      
	    }
	  }
	  if (bFound==false) return null;
	  return strReturn;
	}
});

// Dazugehörige Funktion für Bildwechsel auf Stage

	// Stage IMG-Tag ersetzen

		if ($.getURLParam("link")==null) {
			var menu = document.getElementById("startseite");
			menu.className = "link_on";
