How to submit a form WITHOUT clicking a submit button?

I want the form to be submitted when 开发者_StackOverflowthe user chooses one of the radio button options. I know how to do this with select fields:

<select name='something' onchange="this.form.submit()">

But how to do this with radio buttons?

You can use onclick:

<input type="radio" name="something" onclick="this.form.submit()">

You can test for compatibility (of keyboard entry like left/right or tabbing then pressing space/enter and even keyboard only navigation plugins) using this example.

Try hooking into the onclick event.

<input type="radio" name="something" value="somethingvalue" onclick="this.form.submit();" />
