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?

Sadly I can’t use imageflip like i did on javascript sites, but auto-complete know this keyword. Anyway, this doesn’t work:

document.getElementById(id).imageflip.src = "path/to/new.img"

but this do:

document.getElementById(id).src = "path/to/new.img"

Does anyone have a good idea how to flip an image on click?

How can I prevent mobile phones from switching off the screen? I cant find any information in documentation or any result to this in google. Is that even possible?
