使用方法
target.addEventListener(type, listener, useCapture);
target 文档节点、document、window 或 XMLHttpRequest。
type 字符串，事件名称，不含“on”，比如“click”、“mouseover”、“keydown”等。
listener 实现了 EventListener 接口或者是 JavaScript 中的函数。
useCapture 是否使用捕捉，看了后面的事件流一节后就明白了，一般用 false
事件触发时，会将一个 Event 对象传递给事件处理程序，比如：
document.getElementById("testText").addEventListener("keydown", function (event) { alert(event.keyCode); }, false);
实例
document.body.addEventListener('mousemove', function moveHandler(e){
if ( e.clientY > 1200 ) doSomething(); // 如果 y > 1200 做你要做的事
document.body.removeEventListener('mousemove', moveHandler, false);
}, false);
