Bug 60400 – Missing focus change event on form submit.

• Status: RESOLVED
• Resolution: INVALID
• Component: Forms

[Varun Jain]

WebKit should reset focus and generate a focus change event when a form is submitted using the return key. Currently, the focus controller is not triggered and the WebViewClient is not informed that the focused element has lost focus.

Why should WebKit do that?

Hi Alexey, thanks for looking into this. As I understand, the WebViewClient is notified through WebViewClient::focusedNodeChanged() whenever there is a change of focus on the webpage. When a form is submitted using the return key, the node currently focused looses focus. But no notification is sent to the WebViewClient because FocusController is never informed.

I don't think so.
If a form target is an iframe, the text field doesn't lost focus.

Hi Alexey,Kent...
I have added a test to the patch to illustrate the issue. The Test fails on the last expectation due to the lack of focus change events. I have also added a possible fix to the patch. Please have a look.

I confirmed 'blur' event was not fired in such case with IE9, Firefox4, and Opera 11.  So I'm negative about adding setFocusedNode() call.

Varun,
What problem are you trying to solve?
