Detect double tap on ipad or iphone screen using javascript

Question

I'd like to detect if a user has double tapped on an ipad or iphone.

Does a javascript-event exist which would provide this functionality?

Answer 1

This could be used for a double tap or a double click. In pure javascript:

var mylatesttap; function doubletap() {     var now = new Date().getTime();    var timesince = now - mylatesttap;    if((timesince < 600) && (timesince > 0)){      // double tap        }else{             // too much time to be a doubletap          }     mylatesttap = new Date().getTime();  }
