detachEvent&addEventListener绑定时怎么很好的传参或者this对象呢？

不用传，evemnt.srcElement或者event.target就是

先谢谢回复!
我像这样:this.binder(this.$(this.rightId), "click", this.move);
---------------------------------------------------------------
this.binder = function(obj, action, callback) {
if (document.all) {
obj.attachEvent("on" + action, caller);
} else {
obj.addEventListener(action, caller, false);
}
};
----------------------------------------------------------------
this.move = function(e) {
var obj = window.event.srcElement || e.target;
alert(obj);
}
为什么为undefined
谢谢孟大哥!
