A jQuery plugin to selectively disable the iOS double-tap-to-zoom action on specific page elements (and have that generate two click events instead).

(function($) {
  var IS_IOS = /iphone|ipad/i.test(navigator.userAgent);
  $.fn.nodoubletapzoom = function() {
    if (IS_IOS)
      $(this).bind('touchstart', function preventZoom(e) {
        var t2 = e.timeStamp
          , t1 = $(this).data('lastTouch') || t2
          , dt = t2 - t1
          , fingers = e.originalEvent.touches.length;
        $(this).data('lastTouch', t2);
        if (!dt || dt > 500 || fingers > 1) return; // not double-tap

        e.preventDefault(); // double tap - prevent the zoom
        // also synthesize click events we just swallowed up
        $(this).trigger('click').trigger('click');
      });
  };
})(jQuery);

Hey johan,

thanks for the snippet!
I'd just recommend adding a "return this;" to make it chainable.

Thanks for this!

Thanks for this!

Thank you for this. I am using the presses of the button to call a function to increment a counter. I need the double taps to call my function twice. Might it be OK for me to call $(this).trigger('click').trigger('click'); twice in the section // also synthesize click events we just swallowed up.

Thank you again.

Thanks for your idea, I need to port this snippet to javascript.

Works great, thanks a lot!
I suggest lowering the time between the two taps because it prevents fast scrolling of the page.
200ms should be enough.

I think it should be $(this).trigger('click') at the end, not $(this).trigger('click').trigger('click'). Otherwise, I receive 3 clicks for one double-tap.
