Answer 1

Not quite - as long as the disabled attribute is present, the control will be disabled. To re-enable the control, you have to remove the disabled attribute. Something like this:

var element = $(this).closest("fieldset").find("input:not(:checkbox), select,textarea");
if (this.checked) {
  element.attr('disabled', 'disabled');
} else {
  element.removeAttr('disabled');
}

Your code works for me:

Were you having some specific issue?

HTML (updated to include submit button)

<fieldset>

    <input type='checkbox' /> Click me
    <br><br>
    <input type='text' />
    <select>
        <option>one</option>
    </select>
    <textarea>
        sometext
    </textarea>

    <input type='submit' />

</fieldset>

jQuery

$(':checkbox').change(function() {
    $(this).closest("fieldset")
        .find("input:not(:checkbox), select,textarea")
        .attr('disabled', this.checked);  
    });​
