共分三个步骤：
第一步： 在<head></head>加入下列代码： <style>
.spanstyle { position:absolute; visibility:visible; top:-50px; font-size:9pt; font-family:宋体; font-weight:bold; } </style> <script> var message="★ ★ ★ ★ 欢 迎 光 临 孟 宪 会 之 精 彩 世 界！ ★ ★ ★ ★ "//可以任意更改！ message=message.split(" ") var step=8 var stepbasic=8 //设定字的间距 var x,y var flag=0 var xpos=new Array() for (i=0;i<=message.length-1;i++) { xpos[i]=-100 } var ypos=new Array() for (i=0;i<=message.length-1;i++) { ypos[i]=-100 } var spacebetweenwords=new Array() for (i=0;i<=message.length-1;i++) { spacebetweenwords[i]=stepbasic+step*message[i].length-1 } var colorstep=Math.round(255/message.length-1) var colorrgb=new Array() for (i=0;i<=message.length-1;i++) { colorrgb[i]=i*colorstep } var wordcolor=new Array() for (i=0;i<=message.length-1;i++) { var colhex_left = Math.floor(colorrgb[i]/16) var colhex_right= colorrgb[i]-(colhex_left*16) if (colhex_left == 10) {colhex_left="A"} if (colhex_left == 11) {colhex_left="B"} if (colhex_left == 12) {colhex_left="C"} if (colhex_left == 13) {colhex_left="D"} if (colhex_left == 14) {colhex_left="E"} if (colhex_left == 15) {colhex_left="F"} if (colhex_right == 10) {colhex_right="A"} if (colhex_right == 11) {colhex_right="B"} if (colhex_right == 12) {colhex_right="C"} if (colhex_right == 13) {colhex_right="D"} if (colhex_right == 14) {colhex_right="E"} if (colhex_right == 15) {colhex_right="F"} wordcolor[i] =""+colhex_left+colhex_right } function handlerMM(e){ x = (document.layers) ? e.pageX : document.body.scrollLeft+event.clientX y = (document.layers) ? e.pageY : document.body.scrollTop+event.clientY flag=1 } function makesnake() { if (flag==1 && document.all) { for (i=message.length-1; i>=1; i--) { xpos[i]=xpos[i-1]+spacebetweenwords[i-1] ypos[i]=ypos[i-1] } xpos[0]=x+stepbasic ypos[0]=y for (i=0; i<message.length-1; i++) { var thisspan = eval("span"+(i)+".style") thisspan.posLeft=xpos[i] thisspan.posTop=ypos[i] } } else if (flag==1 && document.layers) { for (i=message.length-1; i>=1; i--) { xpos[i]=xpos[i-1]+spacebetweenwords[i-1] ypos[i]=ypos[i-1] } xpos[0]=x+stepbasic ypos[0]=y for (i=0; i<message.length-1; i++) { var thisspan = eval("document.span"+i) thisspan.left=xpos[i] thisspan.top=ypos[i] } } var timer=setTimeout("makesnake()",30) } </script> 第二步：
在<body>里加入： onLoad="makesnake()" style="width:100%;overflow-x:hidden;overflow-y:scroll"
第三步： 在<body></body>里加入： <script>
<!-- 代码开始 for (i=0;i<=message.length-1;i++) { document.write("<span id='span"+i+"' class='spanstyle'>") document.write("<font color='"+wordcolor[i]+wordcolor[16-i]+wordcolor[i]+"'>"+message[i]+"</font>") document.write("</span>") } if (document.layers){ document.captureEvents(Event.MOUSEMOVE); } document.onmousemove = handlerMM; // -代码结束 --> </script> **************************************************
