Touch tablet: prevent touchmove/touchstart without lag time

How do I prevent the touchmove (touchstart?) action on a Blackberry tablet? For example, the user must not be allowed to zoom in on an image or form/button. I have tried

<img src= "image.jpg" ontouchstart="event.preventDefault();">

And also (both within and outside $(document).ready )

document.body.addEventListener('touchstart', function(e){ e.preventDefault(); });

These sort of seem to work, but not quite. When the page first loads, there is sometimes a lag time where I can zoom in. Not always, but enough for it to be a problem.

Is there a way to prevent this lagtime - or a nice way to prevent the page from displaying until I know preventDefault has been "activated"?

  • I needed this header- That did the trick.
