Button GET\SET Value

Button GET\SET Value

Because the button is a part of a form element and can be used as a checkbox or radio, it should have a get and set value method.

Though the values inherited from markup, i would propose to add this feature. For example I'm working with an Ajax form, and i need to change state of button each time i get a response, that kind of  behavior i don't need while submitting the form to a URL.
