JavaScript Checkbox Question

devanium · Jan 20, 2006

Does anyone know how I can use JavaScript to make sure a checkbox is checked before a form is allowed to be submitted? Also, if the button already has an onClick element, can I add a second one, or do I have to modify the onClick script it's referring to to include the checkbox JavaScript too?

Any help is appreciated, thanks

Try something like this:

Code:

if(window.document.example1.my_checkbox.checked=true)
{
alert('The box is checked!')
}
else
{
window.document.example1.my_checkbox.checked=true;
alert('The box was not checked!');
}

}

So I would have that as a javascript file at the top of the page, and then have the onClick on the submit button for the form?

Yes, I believe thats how it works. (I'm still learning also, so I maybe wrong).
