Using jQuery set the disabled property and remove the disabled attribute

The difference between the disabled and readOnly form:
Readonly only for input (text / password) and textarea effective, and valid for all disabled form elements, including select, radio, checkbox, button and so on.
But form elements in the use of the disabled, when we submit a form with POST or GET way, then the value of this element will not be passed out, and readonly The value is passed out (this happens we will be in a textarea form element is set to disabled or readonly, but it can be used submitbutton).
