JS闭包实例

学习闭包的时候看的例子，记录上来，以便以后可以再次深入理解！

<script type="text/javascript">
<!--
//事件处理封装函数
function f(obj,method){
        return function(e){
                e = e || window.event;
                return obj[method](e,this);
            }
    }
//事件处理器函数
function g(tagName){
        return function(){
             var ele = document.getElementsByTagName(tagName);
             if(ele){
                 for(var i in ele){
                    ele[i].onclick = f(g,"click");
                    ele[i].onmouseover = f(g,"over");
                    ele[i].onmouseout = f(g,"out");
                }
             }
        }
    }
//事件处理方法
g.click = function(event,element){ element.style.backgroundColor = "red"; };
g.over = function(event,element){element.style.backgroundColor = "blue";};
g.out = function(event,element){element.style.backgroundColor = "transparent"};
window.onload = g("p");
