Jquery listbox restrict the particular options to select

I have a set of listboxes

Here i want to readonly the particular options i.e 

        <select name="list" id="l1">
        <option value="1" selected="selected" >1</option>
        <option value="2">2</option>
        <option value="3">3</option>
        <option value="4">4</option>
        <option value="5">5</option>
        <option value="test">test</option>
        <option value="test2">test2</option>
        </select>

In the above list box i want to restrict the 'test' and 'test2 ' options as read only. User should not select these two options ('test', 'test2'). Is it possible in jquery

Please do the needful. Thanks

Add a class to the disabled items (optionally graying them out with the class). Store the default value for the select list using the jQuery data attribute. On change, monitor whether a disabled option has been chosen. If so then revert to the stored value. Otherwise update stored value and continue.

http://jsfiddle.net/mrtsherman/Ew5uW/

//add class to disabled items
var len = $('option[value^="test"]').addClass('disabled');

//store default selected item value
$('#l1').data('selValue', $('#l1').val());

//monitor change events
$('#l1').change(function() {
    //if a disabled option is chosen then restore prev value
    if ($(this).children('option:selected').hasClass('disabled')) {
        $(this).val($(this).data('selValue'));
    }
    //otherwise store new value 
    $(this).data('selValue', $(this).val());
});​

Try this ,

$("#l1").change(function()
{
if($(this).val()=="test" || $(this).val()=="test2")
 {
   alert("This option is disabled..");
   return false;
 }
})
