Question

Is it possible to enable or disable a button which is in a form, based on a select (drop down) option which isn’t in a form? I don’t have any code, I will have it (or not) based on your answer to my question 😀

Answer 1

A quick demonstration: http://jsfiddle.net/mblase75/vZacx/

$('#picker').on('change', function() {
    $('#' + $(this).val()).prop('disabled', false)
        .siblings().prop('disabled', true);
});​
