Javascript onmouseout睡觉？

Question

在Javascript中，我希望我的onmouseout事件在生效前三秒钟进入睡眠/暂停/等待/（不确定这里的正确术语）。这是如何完成的？

感谢

Answer 1

function outfunction(event) {
    var that = this; // to be able to use this later.
    window.setTimeout(function() {
        …
    /* you can use 'that' here to refer to the element
       event is also available in this scope */
    }, 3000);
}

Answer 2

var doSomething = function () {
    //Some code will here after 3 seconds of mouseout
};

anElement.onmouseout = function () {
   setTimeout(doSomething, 3000);
};

以上代码的作用是在调用doSomething 3秒后执行onmouseout函数
