Definition and Usage

The value property sets or returns the value of the value attribute of the radio button.

For radio buttons, the contents of the value property do not appear in the user interface. The value property only has meaning when submitting a form. If a radio button is in checked state when the form is submitted, the name of the radio button is sent along with the value of the value property (if the radio button is not checked, no information is sent).

Tip: Define different values for radio buttons in the same group, to identify (on the server side) which one was checked.


Browser Support

The value property is supported in all major browsers.
