怎么让setTimeout执行时this所在的指针不是window.
下面代码的console.log(this); //this是指向window了 .而不是li元素本身..要怎么做才能让它指向li

HTML code

<ul id="list"><li><a href="" title="iphone_ios">苹果</a><div class="popDiv"></div></li><li><a href="" title="安卓_java">google</a><div class="popDiv"></div></li><li><a href="" title="wp">微软</a><div class="popDiv"></div></li><li><a href="" title="mysql">甲骨文</a><div class="popDiv"></div></li><li><a href="" title="全球最大的社交网站">facebook</a><div class="popDiv"></div></li></ul>var list = document.getElementById("list");var oli = list.getElementsByTagName("li");for(var i=0; i<oli.length; i++){oli[i].onmouseover = function(){setTimeout(arguments.callee,20);console.log(this); }}

JScript code

var list = document.getElementById("list");var oli = list.getElementsByTagName("li");for(var i=0; i<oli.length; i++){    oli[i].onmouseover = function(){        var self = this;        var callee = arguments.callee;        setTimeout(function(){callee.call(self)},20);        console.log(this);     }}
