html/javascript/php run script onclick checkbox

Question

This should be a very easy thing to do but I can't find a good reference on how to do it.

I want to submit a form upon clicking a checkbox. To make it a one click process and save user the step of clicking the check box and then clicking form submit, I'd like the form to be submitted upon clicking the checkbox.

My question is do I need to call a javascript function to do this or can html do this natively?

<form action="post.php" method="post"><input type="checkbox" name="done" id="done" value="1" onclick="post.php"></input></form>

doesn't seem to work. Do I have to call a javascript function, or am I missing something simple. Thanks

Answer 1

Try onclick="this.parentNode.submit()"

Answer 2

Try to replace

onclick="post.php"

By

onclick="submit();"
