*程序制作：李勃 
*制作时间：2006-06-05
*功能：对联广告
*用法：首先创建两个对象，分别是左右两个广告DIV对象；
	   再执行该对象的initDivOfConvenienceLink()或initDivOfConvenienceLink1()函数；
	   如：
	<script language="javascript" src="duilian.js"></script>
	<script>
	str1='<table width="100%" height="100%" border="0" cellpadding="1" cellspacing="1"><tr bgcolor="#0099CC"><td>sdf</td></tr></table>';
	str2='<img src="p1.gif">';
	var wokao=new ConvenienceLink("wokao",20,20,str1,2,20);
	wokao.initDivOfConvenienceLink();
	var w=new ConvenienceLink2("w",20,20,str2,2,20);
	w.initDivOfConvenienceLink2();
	</script>
*对象参数说明：
ObjName:对象名称；
Width：宽度；
Height：高度；
contentHTML：广告内容的HTML代码；
spaceOfLeft：左边广告距左边的距离；
spaceOfRight：右边广告距右边的距离；
spaceOfTop：距上边的距离；
linkURL:链接地址，为空的话就没有；
另外说明：所有的HTML内容是放在一个层div里面，无边框，透明色，overflow=hidden；可以调整其宽度和高度来适当调整位置；
*
