要完成此效果需要两个步骤
第一步：把如下代码加入到<head>区域中
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
timeID = 5;
stcnt = 11;
msg = "<<=== WELCOME TO www.jojoo.net! ===>>";
wmsg = new Array(33);
wmsg[0] = msg;
blnk = " ";
for (i = 1; i < 32; i++) {
b = blnk.substring(0, i);
wmsg[i] = "";
for (j = 0; j < msg.length; j++) wmsg[i] = wmsg[i] + msg.charAt(j) + b;
}
function wiper() {
if (stcnt > -1) str = wmsg[stcnt];
else str = wmsg[0];
if (stcnt-- < -40) stcnt = 31;
status = str;
clearTimeout(timeID);
timeID = setTimeout("wiper()", 150);
}
// End -->
</script>
第二步：把“OnLoad="wiper()"”加在<body>标记里
例如：<body OnLoad="wiper()">
减小字体
增大字体
