Preventing a form submission

[Tony Nelson]

Hi All,

Still using Tapestry 5.3.8 and tapestry-jquery 3.3.10, and I'm having a problem stopping form submission on a validation error. I'm listening for Tapestry.FORM_VALIDATE_EVENT, and that works fine.  I've tried setting event.result = false and just plain returning false, but nothing stops the form from submitting.

Here is what I have tried:

            $("#" + specs.form).on(Tapestry.FORM_VALIDATE_EVENT, function (event) {

                console.dir(event);

                event.result = false;

                return false;

            });

I even tried throwing an exception.  What is the proper way to register an error and stop form submission?

Thanks

Tony

Hi

Maybe event.stopPropagation() or event.preventDefault()

That will definitely stop it, but there is other code that needs to be executed, I presume to display error messages.  Looking at the source for tapestry-jquery.js, https://github.com/got5/tapestry5-jquery/blob/maint-3.3.x/src/main/resources/org/got5/tapestry5/jquery/tapestry-jquery.js , the event is triggered on line 594.  I need to figure out how I'm supposed to set thatOpt.validationError, that is checked on line 596.

This is the standard/correct way to do cross field validation, or is there a better way?

Thanks

Tony
