。。。addHandler代码都没写你想怎么样。。
addHandler: function (element, type, handler) {
if (element.addEventListener) element.addEventListener(type, handler, false);
else if (element.attachEvent) element.attachEvent('on' + type, handler);
else element['on' + type] = handler;
}
addHandler: function (element, type, handler) {
},
改为
addHandler: function (element, type, handler) {
handler();
},
