JS check if checkbox is checked?

[adamck]

Hi Guys.
What js is needed to check that a checkbox is checked when submitting a form?
I need an alert if its not checked and for the form to submit correctly when it is checked.
Thanks

OK so im doing this JS

if ($('newusers___Terms').checked == true) {
document.getElement('.fabrikActions').show();
}
else{
document.getElement('.fabrikActions').hide();}

Which works by hiding the submit button when the box is unchecked.
But when its checked again it doesnt show the submit button.
Why??

that suggests your js code is not right in that the if statement is never true.
Take a look at this wiki entry for details on how to deal with element values and checkboxes in fabrk:
