js移除事件 js绑定事件实例应用

复制代码 代码如下:

function addEvents(target, type, func) {
if (target.addEventListener) //非ie 和ie9
target.addEventListener(type, func, false);
else if (target.attachEvent) //ie6到ie8
target.attachEvent("on" + type, func);
else target["on" + type] = func; //ie5
};

复制代码 代码如下:

function removeEvents(target, type, func){
if (target.removeEventListener)
target.removeEventListener(type, func, false);
else if (target.detachEvent)
target.detachEvent("on" + type, func);
else target["on" + type] = null;
};
