send form by email when checked

This may sound weird and I don't know if it is possible but here is what I am trying to do:

when a user checks a checkbox I want it to automatically send me an email.

I don't want the user to have to click a submit button first. Just have them click on a checkbox and doing that will send me an email.

Any Ideas?

 

You have to use " onchange" function in your form.

Something like this:

<SELECT name="dzien" onchange="your.form.submit();">
........
</SELECT>

Code (markup):

with radio button looks like this:

<INPUT type="radio" name="fodp" onclick="your.form.submit();">

Code (markup):

 

Assuming you want the form to post back and submit the above will work fine.
If you are looking to simply "collect" and action(such as a radio button is clicked), you may want to consider a partial post back via ajax or an update panel.
