基于jquery和dot.js弹出框插件，兼容IE6+等其他浏览器。
思想：弹出框元素插入body节点中，并在页面垂直居中显示（fixed定位），触发确定和关闭事件绑定。
注意ie6包含两个问题：
一、select、flash不能遮罩，采用iframe。
二、fixed属性采用滚动时重新计算高度或在样式中采用表达式计算expression。
源码分析：
1、creatHtml：采用doT.js初始化元素添加到body中；
2、show：设置宽度，高度，居中显示；
3、events：为关闭和确定绑定事件；
4、removeCallback：移出元素节点，如有执行回调方法；
5、ie6fixed：ie6中fixed的兼容性处理。
参数使用说明：
width：定义弹出框的宽度，默认值是400。
height：定义弹出框的高度，默认值是100.
title：定义弹出框的标题，默认值是空。
html：定义弹出框的内容，默认值是空。
type：定义弹出框的类型，默认值是default，其他conform和alert。
closed: 标题栏中的关闭按钮，回调方法，默认为null。
conform：包含name指按钮的名称，默认值为确定，callback回调方法，默认值为null。
cancel：包含name指按钮的名称，默认值为取消，callback回调方法，默认值为null。
备注：如果使用conform或alert时，不设置type类型是不起作用。
放在页面底部，作为公用部分：
使用方法：
$.Dialog.init({ height: 180, title: "弹出框", html: "亲，默认弹出框哦", closed: function() { alert("关闭"); } });
