This is a quick tip on how to support the onChange behavior for a select box in IE8.
For some reason IE 8 does not handle the onChange attribute of a select box.
<select name="bowsers" id="browsers" onChange="alert('test');"> <option>FF4</option> <option>IE</option> <option>Chrome</option> </select>
Here is a fix than can be used to make this working
<select name="bowsers" id="browsers"> <option>FF4</option> <option>IE8</option> <option>Chrome</option> </select> <script type="text/javascript"> var selectmenu = document.getElementById("browsers"); selectmenu.onchange = function() { alert('test'); } </script>
