1、在桌机上新建文本文档，命名为晓博JavaScript特效测试.txt，在文本文档里中入HTML文档的基本元素如下，并保存。<html><head><title>晓博JavaScript特效测试</title></head><body><div id="zy"> <div id="login"></div> <div id="daohang"> <ul> <li><a href="index.html">首页</a></li> <li><a href="jianjie.html">七夕简介</a></li> <li><a href="#">七夕节传说</a></li> <li><a href="#">七夕节习俗</a></li> <li><a href="#">诗词& 歌谣</a></li> <li><a href="#">七夕节寄语</a></li> </ul> </div></div></body></html>

2、第一步:把如下代码加入<body>区域中,并重名文档为HTML文件<LAYER NAME="a0" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#ffffff" CLIP="0,0,1,1"></LAYER><LAYER NAME="a1" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#fff000" CLIP="0,0,1,1"></LAYER><LAYER NAME="a2" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#ffa000" CLIP="0,0,1,1"></LAYER><LAYER NAME="a3" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#ff00ff" CLIP="0,0,1,1"></LAYER><LAYER NAME="a4" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#00ff00" CLIP="0,0,1,1"></LAYER><LAYER NAME="a5" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#FF00FF" CLIP="0,0,1,1"></LAYER><LAYER NAME="a6" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#FF0000" CLIP="0,0,1,1"></LAYER><LAYER NAME="a7" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#ffffff" CLIP="0,0,2,2"></LAYER><LAYER NAME="a8" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#fff000" CLIP="0,0,2,2"></LAYER><LAYER NAME="a9" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#ffa000" CLIP="0,0,2,2"></LAYER><LAYER NAME="a10" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#ff00ff" CLIP="0,0,2,2"></LAYER><LAYER NAME="a11" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#00ff00" CLIP="0,0,2,2"></LAYER><LAYER NAME="a12" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#0000ff" CLIP="0,0,2,2"></LAYER><LAYER NAME="a13" LEFT=10 TOP=10 VISIBILITY=SHOW BGCOLOR="#FF0000" CLIP="0,0,3,3"></LAYER><div id="starsDiv" style="position:absolute;top:0px;left:0px"><div style="position:relative;width:1px;height:1px;background:#ffffff;font-size:1px;visibility:visible"></div><div style="position:relative;width:1px;height:1px;background:#fff000;font-size:1px;visibility:visible"></div><div style="position:relative;width:1px;height:1px;background:#ffa000;font-size:1px;visibility:visible"></div><div style="position:relative;width:1px;height:1px;background:#ff00ff;font-size:1px;visibility:visible"></div><div style="position:relative;width:1px;height:1px;background:#00ff00;font-size:1px;visibility:visible"></div><div style="position:relative;width:1px;height:1px;background:#0000ff;font-size:1px;visibility:visible"></div><div style="position:relative;width:1px;height:1px;background:#FF0000;font-size:1px;visibility:visible"></div><div style="position:relative;width:2px;height:2px;background:#ffffff;font-size:2px;visibility:visible"></div><div style="position:relative;width:2px;height:2px;background:#fff000;font-size:2px;visibility:visible"></div><div style="position:relative;width:2px;height:2px;background:#ffa000;font-size:2px;visibility:visible"></div><div style="position:relative;width:2px;height:2px;background:#ff00ff;font-size:2px;visibility:visible"></div><div style="position:relative;width:2px;height:2px;background:#00ff00;font-size:2px;visibility:visible"></div><div style="position:relative;width:2px;height:2px;background:#0000ff;font-size:2px;visibility:visible"></div><div style="position:relative;width:3px;height:3px;background:#FF0000;font-size:3px;visibility:visible"></div></div><SCRIPT LANGUAGE="JavaScript"><!-- Original: Kurt Grigg (kurt.grigg@virgin.net) --><!-- Web Site: http://freespace.virgin.net/kurt.grigg --><!-- This script and many more are available free online at --><!-- The JavaScript Source!! http://javascript.internet.com --><!-- Beginvar Clrs = new Array(6);Clrs[0] = 'ff0000';Clrs[1] = '00ff00';Clrs[2] = '000aff';Clrs[3] = 'ff00ff';Clrs[4] = 'fff000';Clrs[5] = 'fffff0';var yBase = 200;var xBase = 200;var step;var currStep = 0;var Xpos = 1;var Ypos = 1;var Xs = 200;var Ys = 400;if (document.layers) {window.captureEvents(Event.MOUSEMOVE);}if (document.all) {function MoveHandler() {Xpos = document.body.scrollLeft+event.x;Ypos = document.body.scrollTop+event.y;}document.onmousemove = MoveHandler;}else if (document.layers) {function xMoveHandler(evnt) {Xpos = evnt.pageX;Ypos = evnt.pageY;}window.onMouseMove = xMoveHandler;}function Comet() {if (document.all) {yBase = window.document.body.offsetHeight / 4;xBase = window.document.body.offsetWidth / 4;}else if (document.layers) {yBase = window.innerHeight / 4;xBase = window.innerWidth / 4;}if (document.all) {for ( i = 0 ; i < starsDiv.all.length ; i++ ) {step = 3;starsDiv.all[i].style.top = Ypos + yBase*Math.cos((currStep + i*4)/12)*Math.cos(0.7+currStep/200);starsDiv.all[i].style.left = Xpos + xBase*Math.sin((currStep + i*3)/10)*Math.sin(8.2+currStep/400);for (ai = 0; ai < Clrs.length; ai++) {var c=Math.round(Math.random()*[ai]);}starsDiv.all[i].style.background = Clrs[c]; }}else if (document.layers) {for ( j = 0 ; j < 14 ; j++ ) { //number of NS layers!step = 6;var templayer = "a"+j;document.layers[templayer].top = Ypos + yBase*Math.cos((currStep + j*4)/12)*Math.cos(0.7+currStep/200);document.layers[templayer].left = Xpos + xBase*Math.sin((currStep + j*3)/10)*Math.sin(8.2+currStep/400);for (aj=0; aj < Clrs.length; aj++){var c=Math.round(Math.random()*[aj]);}document.layers[templayer].bgColor = Clrs[c]; }}currStep += step;setTimeout("Comet()", 5);}Comet();// End --></script>
3、用IE浏览器打开晓博JavaScript特效测试.html文件，可以看到跟随鼠标旋转礼花背景特效，如下图
