            name=VTI-GROUP type=hidden value=1><!--webbot              bot="SaveResults" endspan i-checksum="43406" --> 

            <P align=center><TEXTAREA cols=50 name=S1 rows=4>脚本说明:
第一步:把如下代码加入&lt;body&gt;区域中
&lt;SCRIPT LANGUAGE="JavaScript"&gt;
	var newtop=0
	var newleft=0
	if (navigator.appName == "Netscape") {
		layerStyleRef="layer.";
		layerRef="document.layers";
		styleSwitch="";
		}
		else
		{
		layerStyleRef="layer.style.";
		layerRef="document.all";
		styleSwitch=".style";
		}

	function doMouseMove() {

		layerName = 'iit'

		eval('var curElement='+layerRef+'["'+layerName+'"]')
		eval(layerRef+'["'+layerName+'"]'+styleSwitch+'.visibility="hidden"')
		eval('curElement'+styleSwitch+'.visibility="visible"')
		eval('newleft=document.body.clientWidth-curElement'+styleSwitch+'.pixelWidth')
		eval('newtop=document.body.clientHeight-curElement'+styleSwitch+'.pixelHeight')
		eval('height=curElement'+styleSwitch+'.height')
		eval('width=curElement'+styleSwitch+'.width')
		width=parseInt(width)
		height=parseInt(height)
		if (event.clientX &gt; (document.body.clientWidth - 5 - width))
		{
		newleft=document.body.clientWidth + document.body.scrollLeft - 5 - width
		}
		else
		{
		newleft=document.body.scrollLeft + event.clientX
		}
		eval('curElement'+styleSwitch+'.pixelLeft=newleft')

		if (event.clientY &gt; (document.body.clientHeight - 5 - height))
		{
		newtop=document.body.clientHeight + document.body.scrollTop - 5 - height
		}
		else
		{
		newtop=document.body.scrollTop + event.clientY
		}
		eval('curElement'+styleSwitch+'.pixelTop=newtop')
}

	document.onmousemove = doMouseMove;

&lt;/SCRIPT&gt;
第二步:把如下代码加入&lt;body&gt;区域中
&lt;script language="javascript"&gt;
	if (navigator.appName == "Netscape") {

	}
	else
	{
		document.write('&lt;div ID=OuterDiv&gt;')
		document.write('&lt;img ID=iit src="image1.gif" STYLE="position:absolute;TOP:0pt;LEFT:0pt;width=103;height=28;Z-INDEX:2;visibility:hidden;"&gt;')
		document.write('&lt;/div&gt;')
	}
&lt;/script&gt;
