Gaming JavaScript: Only submit a form if a checkbox is checked?

[SpaceJump]

I want a form to only be submitted if a checkbox is checked. This is what I have so far:

The function:
CODE
ÂÂ


The HTML-Form:
CODE
...
Checkbox

Now if the checkbox is not checked, the message "Checkbox not activated!" comes, but the form is still submitted. How can I prevent this?

It´s been a while that i worked with javascript but i think you need something like this



function check()
{
if (document.formular.theCheckbox.checked)
{
alert('Send Form');
return true;
}
else if (...)
{
alert('Not checked...');
return false;
}

return false;
}

if onSubmit gets true it should send if false not

That is correct.

If onSubmit returns false, the form won´t be send to the server. All you have to do is to create a function that is called onSubmit and it should return true/false. The event must return, also, true/false.
