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
