Javascript onmouseout sleep ？

Question

在 Javascript 中，我希望 onmouseout 事件在生效之前休眠/暂停/等待/(不确定这里的术语是否正确)三秒钟。这是如何实现的？

谢谢

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);
}
