Jquery 长按事件的实现

;(function($,window,documnet){

function registerLongPressEvent(target,cbk,timeInterval) {

var timer;

var evt = document.createEvent('Event');

evt .initEvent('longPress', true, true);

target.addEventListener('mousedown', function() {

timer=setTimeout(function(){

target.dispatchEvent(evt);

},timeInterval);

}, false);

target.addEventListener('mouseup', function() {

clearTimeout(timer);

}, false);

target.addEventListener('longPress',cbk, false);

}

$.fn.addEvent=function(name,cbk){

return this.each(function(){

var $this=$(this);

cbk=cbk||function(){};

switch (name){

case 'longPress':

registerLongPressEvent($this[0],cbk,1000);

break;

default:

break;

}

});

}

$.fn.longPress=function(cbk){

return this.each(function(){

var $this=$(this);

cbk=cbk||function(){};

registerLongPressEvent($this[0],cbk,1000);

});

}

})(jQuery,window,document,undefined);
