up.history up:location:restore

DOM event

This event is emitted when the user is restoring a previous history entry, usually by pressing the back button.

Listeners may prevent up:location:restore and substitute their own restoration behavior:

up.on('up:location:restore', function(event) {
  event.preventDefault()
  document.body.innerText = `Restored content for ${event.location}!`
})

Preventing the event will not prevent the browser from restoring the URL in the address bar.

Important

Custom restoration code should avoid pushing new history entries.
