Hi, i want to do show the "Are you sure you want to leave this page?" in iOS Safari.

How can I do that?

On desktop browsers, I use this snippet (ReactJS):

Code Block javascriptwindow.addEventListener('beforeunload', onUnload)

And the implementation:

Code Block javascriptuseUnload((e) => {
    e.preventDefault() // Required for Firefox
    e.returnValue = ''
    delete e.returnValue
  })

Thanks!

Pretty shocking that there's been no response regarding such an obvious and important issue from Apple support for 3 years already...
