Question

I was wondering if i could get some help with filtering a select list using an input box via jquery.

Here’s what my js looks like, but it doesnt seem to work.
I’m guessing this is because options within a select list are not hide-able.

    <script type="text/javascript">
    $(document).ready(function() {
        $("#inputFilter").change(function() {
            var filter = $(this).val();

            $("#selectList option").each(function() {
                var match = $(this).text().search(new RegExp(filter, "i"));
                if (match > 0) {
                    $(this).show(); // Does not work
                }
                else
                    $(this).hide();
            });
        });
    });
</script>

and here’s my html

<input id="inputFilter" />
<select id="selectList">
    <option value="1111" >1111 - London</option>
    <option value="1112" >1112 - Paris </option>
</select>

Please try this:

$("#inputFilter").change(function() {
    var filter = $(this).val();
    //alert(filter);
    $("#selectList option").each(function() {
        var match = $(this).text().search(new RegExp(filter, "i"));
        //alert(match);
        if (match < 0 && $(this).text() != "--select--")  {                   
            $(this).attr("disabled",true);
        }
        else
            $(this).attr("disabled",false);

    });
});
