638687 - Facility to suppress the Arrow panel popup in HTML form controls

Status: RESOLVED WONTFIX

Attachment: x_moz_errormessage.html

Mounir, I see http://www.w3.org/Bugs/Public/show_bug.cgi?id=10923 got rejected, it would be nice if we have a facility to suppress the Arrow panel popup, but just show the red shadow ring on invalid.

So I suggest if x-moz-errormessage=" " space we should not do popup at all, as well as same for *.setCustomValidity(' ').

Also if x-moz-errormessage = space on the FORM tag, make all the child form controls have default value of space for x-moz-errormessage in each form control.

It's already possible do disable the arrow panel popup by handling the invalid event and returning false.

For example:
<form>
  <input required oninvalid="return false;">
  <input type='email'>
  <input type='submit'>
</form>
-> the popup will never be shown on the first <input>.

<form>
  <input required oninvalid="return false;">
  <input type='email' oninvalid="return false;">
  <input type='submit'>
</form>
-> the popup will never be shown.

The invalid event doesn't bubble so you will have to use addEventListener if you want to disable the popup for an entire form.

In addition, I really believe that x-moz-errormessage is going to be accepted someday. It seems much more appropriate and semantically better than .setCustomValidity() but we really need authors feedback here.

In addition, I don't really like the idea of x-moz-errormessage="" disabling the form popup. It's not the purpose of this attribute.

In an unrelated note, *.setCustomValidity(' ') doesn't disable the form popup. It even keeps the element invalid (you have to pass '' to remove the custom error, not ' '). If the element suffers from another error, this will be useless.
