Rails spinoffs - Apr 2008 - how to replicate onsubmit="return func" with Form.EventObserver

hi,

i wanted to replace the onsubmit="return func(this);" which PREVENTS
form submission when validation fails with this:

	document.observe(''dom:loaded'', function() {
		$$("form.do_validate").each(function(ef){
			new Form.EventObserver(ef,func(ef));
		});
	});

the problem is, the form STILL SUBMITS even when the validation fails
using the above code.

how do i replicate the onsubmit="return func(this);" using prototype?

thanks

If you want to observe a form''s submit method, and stop the default  
behavior, simply do this:

$(''your_form_id'').observe(''submit'',
function(evt){
	evt.stop();
	//do whatever else you like here now, the form won''t go any further
});

walter,

thanks for the help!

i modified my function and incorporated your suggestion to come up
with:

	document.observe(''dom:loaded'', function() {
		$$("form.do_validate").each(function(ef){
			ef.observe(''submit'', function(event){
						if (!checkvalid(ef)) {
							event.stop();
						}
					  });
		});
	});
