I am using this solution to make my option elements disabled in IE:
http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q_22993394.html

Problem is that I want to redirect on some link depending on selected option.

When  I put this code on select box: onChange="window.location.href=this.options[this.selectedIndex].value;" it cannot be done because there is already used this event in code above?

So, I set that code inside script, but it applies on all select boxes on page and I want to make it available only for one of them, on these that have id named "test"

Code from oveve script:
 

window.onload = function() {

	if (document.getElementsByTagName) {

		var s = document.getElementsByTagName("select");
 

		if (s.length > 0) {

			window.select_current = new Array();
 

			for (var i=0, select; select = s[i]; i++) {

				select.onfocus = function(){ window.select_current[this.id] = this.selectedIndex; }

				select.onchange = function(){ restore(this); 

				window.location.href=this.options[this.selectedIndex].value;

				}

				

				emulate(select);

			}

		}

	}

	window.location.href=this.options[this.selectedIndex].value;

}
 

function restore(e) {

	if (e.options[e.selectedIndex].disabled) {

		e.selectedIndex = window.select_current[e.id];

	}

}
 

function emulate(e) {

	for (var i=0, option; option = e.options[i]; i++) {

		if (option.disabled) {

			option.style.color = "graytext";

		}

		else {

			option.style.color = "menutext";

		}

	}

}
 
 

This is my select box for jump menu:
 

<select name="test" id="test">

    <option value="1">1</option>

    <option value="2">2</option>

  </select>

Try this:
1. move the javascript to the end of the html (always recommended);
2. Change this line of code
       var s = document.getElementsByTagName("select");
to
       var s = document.getElementsById("test");

Replace the window.onload function with the following:
window.onload = function() {

	if (document.getElementsByTagName) {

		var s = document.getElementsByTagName("select");

 

		if (s.length > 0) {

			window.select_current = new Array();

 

			for (var i=0, select; select = s[i]; i++) {

				if (select.id == "test") {

					select.onfocus = function(){ window.select_current[this.id] = this.selectedIndex; }

					select.onchange = function(){ restore(this); 

					window.location.href = this.options[this.selectedIndex].value;

					}

				

					emulate(select);

				}

			}

		}

	}

	//window.location.href=this.options[this.selectedIndex].value;

}
