Is your feature request related to a problem? Please describe.

When I click the close button of the form, the application exits directly. I want to confirm again when exiting. The confirmation style is written by the front end. Now we can only add the OnBeforeClose method to the code.

Describe the solution you'd like

Add a close event in js to facilitate confirmation again
