脚本说明: 把如下代码加入<body>区域中 <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="0,0,1,1"></layer> <layer name="a8" left=10 top=10 visibility=show bgcolor="#fff000" clip="0,0,1,1"></layer> <layer name="a9" left=10 top=10 visibility=show bgcolor="#ffa000" clip="0,0,1,1"></layer> <layer name="a10" left=10 top=10 visibility=show bgcolor="#ff00ff" clip="0,0,1,1"></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="0,0,2,2"></layer> <div id="starsDiv" style="position:absolute;top:0px;left:0px"> <div style="position:relative;width:2px;height:2px;background:#ffffff;font-size:2px"></div> <div style="position:relative;width:1px;height:1px;background:#fff000;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#ffa000;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#ff00ff;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#00ff00;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#0000ff;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#FF0000;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#ffffff;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#fff000;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#ffa000;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#ff00ff;font-size:1px"></div> <div style="position:relative;width:2px;height:2px;background:#ff00ff;font-size:2px"></div> <div style="position:relative;width:1px;height:1px;background:#0000ff;font-size:1px"></div> <div style="position:relative;width:1px;height:1px;background:#FF0000;font-size:1px"></div> </div> <SCRIPT LANGUAGE="JavaScript"> <!-- Begin var Clrs = new Array(9); Clrs[0] = 'ff0000'; Clrs[1] = '00ff00'; Clrs[2] = '000aff'; Clrs[3] = 'ff00ff'; Clrs[4] = 'ffa500'; Clrs[5] = 'ffff00'; Clrs[6] = '00ff00'; Clrs[7] = 'ffffff'; Clrs[8] = 'fffff0'; var sClrs = new Array(5); sClrs[0] = 'ffa500'; sClrs[1] = '55ff66'; sClrs[2] = 'AC9DFC'; sClrs[3] = 'fff000'; sClrs[4] = 'fffff0'; var yBase; var xBase; var step; var currStep = 0; var Xpos = 1; var Ypos = 1; var initialStarColor = 'ffa000'; var Mtop = 250; var Mleft = 250; function Fireworks() { if (document.all) { yBase = window.document.body.offsetHeight / 3; xBase = window.document.body.offsetWidth / 8; } else if (document.layers) { yBase = window.innerHeight / 3; xBase = window.innerWidth / 8; } if (document.all) { step = 5; for ( i = 0 ; i < starsDiv.all.length ; i++ ) { for (ai = 0; ai < Clrs.length; ai++) { var c = Math.round(Math.random()*[ai]); } if (currStep < 90) starsDiv.all[i].style.background=initialStarColor; if (currStep > 90) starsDiv.all[i].style.background=Clrs[c]; starsDiv.all[i].style.top = Mtop + yBase*Math.sin((currStep+i*5)/3)*Math.sin(550+currStep/100) starsDiv.all[i].style.left = Mleft + yBase*Math.cos((currStep+i*5)/3)*Math.sin(550+currStep/100) } } else if (document.layers) { step = 5; for ( j = 0 ; j < 24 ; j++ ) { //number of NS layers!
