不停变换的背景颜色[共1步]
====1、将以下代码加入HTML的<body></body>之间：
<body bgColor="#ffffff" onload="chgCol(); pingpong();"> <script language="JavaScript"> <!-- Hide from JavaScript-Impaired Browsers var pos = 10; function initArray() { this.length = initArray.arguments.length; for (var i = 0; i < this.length; i++) { this[i] = initArray.arguments[i]; } } var col=new initArray("4b","5b","8b","8b"); col[0] = "yellow"; col[1] = "coral"; col[2] = "orange"; col[3] = "red"; col[4] = "greenyellow"; col[5] = "lime"; col[6] = "turquoise"; col[7] = "coral"; col[8] = "blueviolet"; col[9] = "violet"; function chgCol() { pos++; if (pos<0||pos>9) { pos = 0; } document.bgColor = col[pos]; setTimeout("chgCol()",5000); /* Change above set to every 10 seconds (1000 = 1 sec) If you wish to speed it up, lower the number. To slow it down, raise the number. */ } var yourwords = "不斷變化背景色彩";var buffer1=" ";var buffer2=" ";var message1=buffer1+yourwords+buffer2;var dir = "left";var speed =150;function pingpong(){if (dir == "left") { message2=message1.substring(2,message1.length)+" "; window.status=message2; setTimeout("pingpong();",speed); message1=message2; if (message1.substring(0,1) == "*") dir="right"; }else { message2=" "+message1.substring(0,message1.length-2); window.status=message2; setTimeout("pingpong();",speed); message1=message2; if (message1.substring(message1.length-1,message1.length) == "*") dir="left"; }}// --></script>
