How to allow popups?

[Mustermann465422]

I'd like to show a popup which is produced by the following Angular/JavaScript Code.

Code: Select all

  @HostListener('window:beforeunload', ['$event'])
onBeforeUnload() {
    return window.confirm('There is the unsaved message....');
}

Right know in the moment when a normal browser shows the popup, JCEF prints to the log:

[INFO:CONSOLE(0)] "Blocked confirm('There is the unsaved message....') during beforeunload."

How can I configure JCEF to show this popup?

The beforeunload dialog will only be shown if the frame attempting to display it has received a user gesture or user interaction. See https://chromestatus.com/feature/5082396709879808

Thanks for the hint.

But this is not the issue. If I don't interact with the frame, this is additionally logged:

Code: Select all

[0116/101526.391:INFO:CONSOLE(0)] "Blocked attempt to show a 'beforeunload' confirmation panel for a frame that never had a user gesture since its load. https://www.chromestatus.com/feature/5082396709879808", source: (0)

But if I interact with the frame, then:

Code: Select all

[INFO:CONSOLE(0)] "Blocked confirm('There is the unsaved message....') during beforeunload."

Do you have another hint?

Updating to the newest version of JCEF solved the issue. Sorry, beginner mistake.
