function getSelectedIndex(element, value) {
    var selectedIndex = 0;
    for(i = 0; i < element.options.length; i++) {
        if(element.options[i].value == value) {
            selectedIndex = i;

• Your problem is in one of three places: 1) the call to getSelectedIndex; 2) the HTML of the desired element; 3) the way the script is inserted in the HTML – Tibos Commented Sep 25, 2013 at 10:16

Use elements.options.indexOf(value) (assuming element is defined, which it doesn't seem to be). By the way, your current design will return zero if the first element matches or there is no match at all. If you really want to write your own version of indexOf, better to return -1 in the case of no match as it does.

actually the message gives you exactly what you need to know. you are trying to read a property of something that does not have a value, and here it is "element" or "element.options", check the place where they are set before the function call. for IE10 it's a strict one, it doesn't support the use of element.options.length

instead you should use:

document.getElementById("optionsID").value

I hope this helps
