Javascript onmouseout睡眠？

Question

在Javascript中，我希望我的onmouseout事件在生效前三秒钟内睡眠/暂停/等待/（不确定此处使用的术语是否合适）。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); 
}; 

什么上面的代码确实是onmouseout 3秒被调用
