How to detect a long touch pressure with javascript for android and iphone?

Question

How to detect a long touch pressure with javascript for android and iphone? native javascript or jquery...

I want something that sound like :

Answer 1

I've done it this way in my Android app:

1. registered events listeners:

   var touchStartTimeStamp = 0;
   var touchEndTimeStamp   = 0;
   
   window.addEventListener('touchstart', onTouchStart,false);
   window.addEventListener('touchend', onTouchEnd,false);
   

2. added functions:

   var timer;
   function onTouchStart(e) {
       touchStartTimeStamp = e.timeStamp;
   }
   
   function onTouchEnd(e) {
       touchEndTimeStamp = e.timeStamp;
   
       console.log(touchEndTimeStamp - touchStartTimeStamp);// in miliseconds
   }
   

3. checked time difference and did my stuff

I hope this will help.
