jQuery Clone Bug解决代码

var $div = $('div.demo'), data = $div.data();
// 获取所有绑定事件:
var events = data.events;
// 除了window对象绑定事件的比较特殊：
var windowEvents = $(window).data('__events__');

var clickHandler = function(){
console.log('click test');
};
$div.click(clickHandler);
events.click.some(function(ev){
return ev.handler === clickHandler;
});

// event.js, jQuery.event.add:
// jQuery 1.4.1
handlers = events[ type ] = {};
// jQuery 1.4.2+
handlers = events[ type ] = [];
// manipulation.js, jQuery.clone : , cloneCopyEvent():
for ( var type in events ) {
for ( var handler in events[ type ] ) {
jQuery.event.add( this, type, events[ type ][ handler ], events[ type ][ handler ].data );
}
}

var self = this;
for ( var type in events ) {
jQuery.each(events[ type ],function(idx,evt) {
jQuery.event.add( self, type, evt.handler, evt.data );
});
}
