My client asked me (a js client side programmer) to change the order of the options so that their company's option appears at the top of a select box when the page loads.

The following code works in FF but fails in IE7 when I try to swap two options:

code:
function load{ 
                var shippingLocation  = document.getElementById("location");
                var swap = null;

                var initiallyFirstItem = shippingLocation.options[0].cloneNode(true);

                var lastPos = null;

                for(var i = 0; i < shippingLocation.length; i++) 
                {
                        if(shippingLocation.options[i].value == "XETEX")
                        { 
                                swap = shippingLocation.options[i];
                                lastPos = i;
                                break;
                        }
                }
                console.debug("sl: " + shippingLocation.options[0]);
                console.debug("s: " + swap);
                shippingLocation.options[0] = swap;
                shippingLocation.options[lastPos] = initiallyFirstItem;
                shippingLocation.selectedIndex = 0;
        }


I get an error on the next to the third line from the bottom: shippingLocation.options[0] = swap;

The error states that "object doesn't support this property or method".

What's IE's beef with switching option items?

This answer is a little late, but try doing something like this:

code:
<select id="foo">
  <option value="0">A</option>
  <option value="1">B</option>
  <option value="2">C</option>
  <option value="3">D</option>
  <option value="4">E</option>
  <option value="5">F</option>
</select>


<script type="text/javascript">

  function moveOptionToTop( indx ){
    var sel = document.getElementById("foo");
    var cpy = sel.options[indx].cloneNode(true);
    sel.options[indx] = null;
    sel.insertBefore(cpy, sel.options[0]);
  }

  moveOptionToTop( 5 );
  
</script>
