var isNS = (navigator.appName == "Netscape");
layerRef = (isNS) ? "document" : "document.all";
styleRef = (isNS) ? "" : ".style";

var queue = new Array();

var NUM_OF_TRAIL_PARTS = 5

for (x=1; x < 6; x++) {
	eval("trailSpriteFrame" + x + " = new Image(28,36);");
	eval("trailSpriteFrame" + x + ".src = 'trailgif" + x + ".gif';");
}

function trailSpriteObj(anID) {
	this.trailSpriteID = "trailSprite" + anID;
	this.imgRef = "trailSprite" + anID + "img";
	this.currentFrame = 1;
	this.animateTrailSprite = animateTrailSprite;
}

function processAnim() {
	for(x=0; x < NUM_OF_TRAIL_PARTS; x++)
			queue[x].animateTrailSprite();
}

	lastItemPos = queue.length - 1;
	lastItem = queue[lastItemPos];
	for (i = lastItemPos; i>0; i--) 
		queue[i] = queue[i-1];
	queue[0] = lastItem;
	
	queue[0].currentFrame = 1;

	if (isNS) { document.captureEvents(Event.MOUSEMOVE); }
	document.onmousemove = processMouse;

setInterval("processAnim();",25);
}	
if (document.all||document.layers)
window.onload = init;

</SCRIPT>

2.在<body>中加入下面的代码
<DIV id="trailSprite1" style="position: absolute; height:28px; width:36px;z-index: 100">
<img src="blanktrail.gif" height=28 width=36 border=0 name="trailSprite1img">
</DIV>
<DIV id="trailSprite2" style="position: absolute; height:28px; width:26px;z-index: 10">
<img src="blanktrail.gif" height=28 width=36 border=0 name="trailSprite2img">
</DIV>
<DIV id="trailSprite3" style="position: absolute; height:28px; width:36px;z-index: 10">
<img src="blanktrail.gif" height=28 width=36 border=0 name="trailSprite3img">
</DIV>
<DIV id="trailSprite4" style="position: absolute; height:28px; width:36px;z-index: 10">
<img src="blanktrail.gif" height=28 width=36 border=0 name="trailSprite4img">
</DIV>
<DIV id="trailSprite5" style="position: absolute; height:28px; width:36px;z-index: 10">
<img src="blanktrail.gif" height=28 width=36 border=0 name="trailSprite5img">
</DIV>
<script language="JavaScript1.2">
if (document.all&&window.print)
document.body.style.cssText="overflow-x:hidden;overflow-y:scroll"
</script>
