Async/Await callbacks
Intro.js main functions to start/stop a tour return a Promise
object. You can also return a Promise
object in the callback functions
(e.g. onbeforechange
) and Intro.js internally waits for that Promise
object to be fulfilled. You can use this concept to perform async I/O (e.g. sending HTTP calls) before moving to the next step of the tour.
In the following example, we are returning a Promise
object and we resolve it after 500ms:
