up.layer up.layer.ask(options)

JavaScript function

Opens an overlay and returns a promise for its acceptance.

It's useful to think of overlays as promises which may either be fulfilled (accepted) or rejected (dismissed).

Opening overlays

Example

Instead of using up.layer.open() and passing callbacks, you may use up.layer.ask(). up.layer.ask() returns a promise for the acceptance value, which you can await:

let user = await up.layer.ask({ url: '/users/new' })
console.log("New user is " + user)

To handle the case that the overlay wasn't completed successful, you can catch the rejected promise reason:

try {
  let user = await up.layer.ask({ url: '/users/new' })
  console.log("New user is",  user)
} catch (reason) {
  console.error("Could not register:", reason)
}
