How to disable an input element in Prototype?

Question

Using Prototype, the Form.Element.disable is said to be disabled the form as a whole. Is there any way to disable only one single input element at a time?

And when I try this:

$$('#signup .button')[0].disbled = false; ## didn't work

Updated

Sorry for all. Actually it works. But I have defined a disabled style in a stylesheet and the style doesn't got applied. Is there any workaround?

Answer 1

You want the disable method.

http://api.prototypejs.org/dom/form/element.html#disable-class_method

For example:

$(id).disable();

Answer 2

This should work:

$$('#signup .button')[0].disable();

Answer 3

Try this:

$$('#signup .button').disable()

Or:

$(id_of_element).disable()

Or:

Form.Element.disable(id_of_element)
