jQuery changing the name of a field

Question

im trying to change the name of a field on the change state of a select list.

I have the following code

<script>
$('#selectintrole').change(function(){
    $('#proven_keyname').val($(this).val());
};
</script>

<select name="item_options" id="selectintrole">
<option value="20030">Universal (20030)</option>
<option value="4545456">Medium (4545456)</option>
<option value="15447">Large (15447)</option>
</select>

<input name="proven" value="1" type="checkbox" id="proven_keyname" />

It doesnt seem to be doing anything though ... when i check the generated source, nothing has changed .... am i missing something?

Not to the value .... i want the name of the checkbox to change to the value of the chosen select option — Cecil

I think you need to bind your change event after the document is ready like so

     $(function () {

        $('#selectintrole').change(function () {

            $('#proven_keyname').val($(this).val());
        });

    });

If you want to change the name attribute then replace with this

$('#proven_keyname').attr('name', $(this).val());

Your code is running before the elements exist.

Move the script below the HTML, or wrap it in $(function() { ... }), which will run it when the page loads.

EDIT: Demo

@Cecil: You're also missing a ) after the handler.

Does .val($(this).val()); just change the 'value' or will it change the 'name' of the checkbox?

@Cecil: For checkboxes, it will check the matched checkboxes with those names. You may want to call .attr('value', string).
