Jquery disable element on checkbox change-Collection of common programming errors

Working demo http://jsfiddle.net/2gbHQ/5/

Good Read http://api.jquery.com/prop/

The .prop() method gets the property value for only the first element in the matched set. It returns undefined for the value of a property that has not been set, or if the matched set has no elements. To get the value for each element individually, use a looping construct such as jQuery’s .each() or .map() method.

Jquery code

$('#dw').change(function() {
    if ($(this).is(':checked')) {
        $('#oo').prop('disabled', false);
    } else {
        $('#oo').prop('disabled', true);
    }
});​
