Edge always submits forms

[jeffijoe]

This is because

_interceptForms: function(e) {
  if (e.target && e.target.action) { return; }
  e.preventDefault();
},

returns when there's an action. In Edge, if there is no action defined on the form, it defaults to the current URL, therefore bypassing e.preventDefault().

hi @jeffijoe what is the expected behavior? that if the e.target.action is the same as the documents url and its edge, preventDefault()? or would that be too open?

[jeffijoe]

The expected behavior is that Intercept will intercept form submissions, but only if they have no actions defined. In Edge, no action means action = current url, and so Intercept always bypasses it.

[linus-amg]

ok, but we wont change the action, the only thing I see which we can do would be to check if the action === url and then not return but continue to prevent, does that sound like a solution?

[jeffijoe]

This is what I did to fix the issue on my end.

// In case Intercept does not catch things for forms (in Edge),
// use our own handler.
$('body').on('submit.interception', 'form', (e) => {
  if ($(e.target).data('bypass')) return;
  e.preventDefault();
});
