jQuery - Tap and Hold
=====================
This jQuery plugin lets you detect a tap and hold event on touch interfaces.
How to use it?
1) Add the jQuery Tap and Hold plugin into your HTML
<script src="jquery.tapandhold.js" type="text/javascript"></script>
2) Bind a tap and hold handler function to the tap and hold event of an element.
$("#myDiv").bind("taphold", function(event){
alert("This is a tap and hold!");
});
You can check a working example in examples/example1.html
