1. Detecting iPad Orientation in Safari using JavaScript

Style your website or re-order your content to match exactly your iPad’s orientation. Here’s an example on how to detect the current orientation of the iPad device either by pressing a button or when the orientation changes, using an event called onOrientationChange…

What<span>'s my Orientation?
</span><span>
</span><span> window.onorientationchange = detectIPadOrientation;
</span><span> function detectIPadOrientation () {
</span><span>
</span><span>	if ( orientation == 0 ) {
</span><span>	 alert ('Portrait Mode, Home Button bottom');
</span><span>	}
</span><span>	else if ( orientation == 90 ) {
</span><span>	 alert ('Landscape Mode, Home Button right');
</span><span>	}
</span><span>	else if ( orientation == -90 ) {
</span><span>	 alert ('Landscape Mode, Home Button left');
</span><span>	}
</span><span>	else if ( orientation == 180 ) {
</span><span>	 alert ('Portrait Mode, Home Button top');
</span>	<span>}
</span> <span>}
</span>

Using the media definition, you can also use CSS Stylesheets:

<link rel="<span">"stylesheet" media="all and (orientation:portrait)" href="portrait.css"/>
<link rel="<span">"stylesheet" media="all and (orientation:portrait)" href="landscape.css"/>

</span>      <span>//we pass the original event object because the jQuery event
</span>      <span>//object is normalized to w3c specs and does not provide the TouchList
</span>      <span>handleTouch(event);
</span>    <span>});
</span>  <span>});
</span> 
  <span>var handleTouch = function(event)
</span>  <span>{
</span>    <span>var touches = event.changedTouches,
</span>            first <span>= touches[0],
</span>            type <span>= '';

</span>    <span>}
</span> 
    <span>var simulatedEvent = document.createEvent('MouseEvent');
</span>    simulatedEvent<span>.initMouseEvent(type, true, true, window, 1, first.screenX, first.screenY, first.clientX, first.clientY, false, false, false, false, 0/*left*/, null);

7. JQUERY CLICK EVENTS ON THE IPAD

A solution to fix it. This was the advice given in the developer docs at apple.com. This basically searches for iPad in the userAgent string (case insensitive). If the user is on an iPad we use touchstart and if not we default back to a standard click. The code you need is:

<span>//iPAD Support
</span>$<span>.fn.addTouch = function(){
</span>  this<span>.each(function(i,el){
</span>    $<span>(el).bind('touchstart touchmove touchend touchcancel',function(){
</span>      <span>//we pass the original event object because the jQuery event
</span>      <span>//object is normalized to w3c specs and does not provide the TouchList
</span>      <span>handleTouch(event);
</span>    <span>});
</span>  <span>});
</span> 
  <span>var handleTouch = function(event)
</span>  <span>{
</span>    <span>var touches = event.changedTouches,
</span>            first <span>= touches[0],
</span>            type <span>= '';
</span> 
    <span>switch(event.type)
</span>    <span>{
</span>      <span>case 'touchstart':
</span>        type <span>= 'mousedown';
</span>        <span>break;
</span> 
      <span>case 'touchmove':
</span>        type <span>= 'mousemove';
</span>        event<span>.preventDefault();
</span>        <span>break;
</span> 
      <span>case 'touchend':
</span>        type <span>= 'mouseup';
</span>        <span>break;
</span> 
      <span>default:
</span>        <span>return;
</span>    <span>}
</span> 
    <span>var simulatedEvent = document.createEvent('MouseEvent');
</span>    simulatedEvent<span>.initMouseEvent(type, true, true, window, 1, first.screenX, first.screenY, first.clientX, first.clientY, false, false, false, false, 0/*left*/, null);
</span>    first<span>.target.dispatchEvent(simulatedEvent);
</span>  <span>};
</span><span>};</span>

8. Easy iPad Gestures in your website with jQuery

jQuery makes this so easy to integrate and use that I couldn’t help but fool around with it. First off all make sure you have the latest jQuery library included in your site. Include it directly from the site like this:

<span>jQuery(document).ready(function($){
</span>	<span>var deviceAgent = navigator.userAgent.toLowerCase();
</span>	<span>var agentID = deviceAgent.match(/(iphone|ipod|ipad)/);
</span>	<span>if (agentID) {
</span>
        <span>// mobile code here
</span> 
	<span>}
</span><span>});</span>

Second step, download the TouchWipe library from the author website OR you can just bind the Touchwipe to the . Include the touchwipe library before the tag. ex:

Then initialise TouchWipe on to the body tag, and give the gestures the chosen action to perform, for this example I just used alerts:

<span>var ua = navigator.userAgent, 
</span>    event <span>= (ua.match(/iPad/i)) ? "touchstart" : "click";
</span>
$<span>("#theElement").bind(event, function() {
</span>     <span>// jquery code
</span><span>}</span>

Touchwipe can be added to a specific div as well rather than the body tag. And there ya go. You could add that to any html page to add swipe Gestures. Source

9. IPHONE/IPAD DOUBLETAP EVENT HANDLER

Enable the use of “doubletap” events on iPhone and iPad devices. The functionality is still available when the plugin is used on Desktop Browser. This means that you don’t have to worry about the environment where the plugin is used. SourceDemo

10. jQuery.UI.iPad plugin

Provides an interface layer to map touch events to jQuery UI interface elements.
