Disorder with confirm dialog

[dd8zc]

Hej,
I have somehting like this:

navigator.vibrate([10,20,30,40]);
booleanAnswer = confirm('Do you have an answer?');  

Unfortunatly navigator.vibrate will start AFTER die confirm dialog. I want it the other way around, any idea how to first vibrate and than ask the question?

It might work using setInterval as described here:
