/*
* Util.$(objid)：获取指定ID的dom对象
*
* Util.ie：判断浏览器是否为IE
*
* List类：模拟java的List，支持iterator
* add(obj)：向List的最后追加一个对象
* addat(index, obj)：在List的index位置插入一个对象
* get(index)：在List获取index位置的对象
* set(index, obj)：在List的替换index位置的对象
* size()：获取List的对象个数
* remove(index)：移除List中index位置的对象
* clear()：清空List
* iterator()：获取到List的迭代对象
*
* Map类：模拟java的Map，支持直接对value的iterator
* put(key, value)：在Map的添加一个key value的键值对
* get(key)：在Map获取键为key的值
* remove(key)：溢出Map中键为key的对象
* containsKey(key)：判断Map中是否存在指定key的对象
* keySet()：获取Map中所有的键的List
* values()：获取Map中所有的值的List
* size()：获取List的对象个数
* clear()：清空List
* iterator()：获取到List的迭代对象
*
* Iterator用法：for(var it = list.iterator(); it.hasNext();) { var item = it.next(); }
*
* Url类：获取url中参数的值，使用var u = new Url(location.search); var value = url.getvalue(para);即可得到
*
* EventHandler类：封装事件方法，可以为事件方法的调用添加参数，屏蔽了浏览器差异
* EventHandler.createEvent(func, ...args)：创建事件对象，args为参数值，需要与func的参数对应，不需要传递event对象
* EventHandler.getEvent()：在事件的处理方法中获取当前的event对象
* EventHandler.getElement(e)：获取触发event事件的dom对象
* EventHandler.attachEvent(obj, eventname, func)：为obj添加eventname事件，事件处理方法为func
* EventHandler.detachEvent(obj, eventname, func)：为obj注销eventname事件的func方法
*
* EventType类：封装了客户端的大多数事件类型，屏蔽了浏览器差异
* 使用方式：EventHandler.attachEvent(obj, EventType.click, func)
* 目前封装了click, rclick, mousedown, mousemove, mouseup, mouseover, mouseout, scroll, focus, blur, change, keypress, keydown, keyup, submit
