Get select element value on event using pure JavaScript

.onchange = function() { ... } seems to overwrite other handlers, so I use addEventListener("change", function() { ... })

A solution that will work with all browsers (including IE8) :

var select_element = document.getElementById('product-form-user-enquiry-type');

select_element.onchange = function() {
    var elem = (typeof this.selectedIndex === "undefined" ? window.event.srcElement : this);
    var value = elem.value || elem.options[elem.selectedIndex].value;
    alert(value);
}​

​document.getElementById('test').onchange = function() {
    alert(this.options[this.selectedIndex].val​​​ue);
};​

Does the above the work?

Edit:

Edited to reflect your select id's etc.

var select_element = document.getElementById('product-form-user-enquiry-type');

select_element.onchange = function(e){
    if (!e)
        var e = window.event;
    var svalue = this.options[this.selectedIndex].value;
    alert( svalue );
}​
