/**
    描述：该文件类似于window页面提示框，取代js系统提示框如(alert、dialog)；
	文件类型：javascript脚本文件
	作者：兰磊 
	时间：2008年12月12日11:24:38
	 
	函数调用说明：
		如果页面上需要使用本脚本，只需在页面中包含本文件如：<script languag="javascript" src="/script/dialog.js"></script>
		调用时主要调用alertDialog函数，调用该函数有两种展示方式：一种是alert、一种是dialog，主要是根据传递的参数来区分

		alertDialog(text, type, str, callback)：
		该函数第一个参数“text”是用来展示提示信息的字符串，只用给一个string类型的字符串就可以了；
			  第二个参数“type”是区分提示框展示样式，如果参数为1时

	需要的参数：
	@param text：需要在页面上显示的文字
	@param type：页面显示的类型，参数为1时 表示页面类型为提示语句，和alter功能相同；
								 参数为2时 表示页面类型为提示语句加“确认”、“取消”，并有返回值。当点击“确认”时返回true，否则就返回false;
	@param str：回调的字符，如果是用户调用，只用给空值，不需要填写。
	@param callback：回调函数名称  如果调用类型为2的时候，需要传递返回函数名，类型为1时可以为空

	样式依赖：
	1、left1a left1b
	2、left2a left2b
	3、left3a left3b

	关于链接
	获得参数articleUrl，该参数保存的是文章信息查询路径，可以按其路径找到文章信息。
