On previous versions, you could call it like for other data :
obj.data('events');
In jQuery 1.8, this direct access was removed, so in recent versions you must call it like this :
$._data(obj[0],"events")
大概的意思是版本可以使用obj.data('event'); JQuery1.8版本取消了obj.data方法，改为$._data方法
注意:$._data(obj[0],"event") 中的obj[0],一定要加上数组[0]下标，否则会取不到数据
-------以下为举例
<html xmlns="http://www.w3.org/1999/xhtml"><head><title></title><script src="/jquery-easyui-1.3.2/jquery-1.8.0.min.js" type="text/javascript"></script><script type="text/javascript">$(function () {$("#btnTest").click(function () { alert('aa'); });$("#btn").click(function () {//判断是否绑定了click事件var objEvt = $._data($("#btnTest")[0], "events");if (objEvt && objEvt["click"]) {//console.info(objEvt["click"]);alert("bind click");}else {alert("Not bind click");}});});</script></head><body><input type="button" id="btn" value="测试是否绑定事件" /><input type="button" id="btnTest" value="被测试按钮" /></body></html>新闻热点
