有什么问题请到<a href='/bbs/forums.php?fid=21'>论坛</a>中发表<br> 第一步：把如下代码加入到<head>区域中 <script language="javascript"> var speed = 10 var pause = 1500 var timerID = null var bannerRunning = false var ar = new Array() ar[0] = "欢迎来到www.webjx.com！ " ar[1] = "欢迎光临网页教学网" ar[2] = "请多提意见，谢谢! " var message = 0 var state = "" clearState() function stopBanner() { if (bannerRunning) clearTimeout(timerID) bannerRunning = false } function startBanner() { stopBanner() showBanner() } function clearState() { state = "" for (var i = 0; i < ar[message].length; ++i) { state += "0" } } function showBanner() { if (getString()) { message++ if (ar.length <= message) message = 0 clearState() timerID = setTimeout("showBanner()", pause) bannerRunning = true } else { var str = "" for (var j = 0; j < state.length; ++j) { str += (state.charAt(j) == "1") ? ar[message].charAt(j) : " " } window.status = str timerID = setTimeout("showBanner()", speed) bannerRunning = true } } function getString() { var full = true for (var j = 0; j < state.length; ++j) { if (state.charAt(j) == 0) full = false } if (full) return true while (1) { var num = getRandom(ar[message].length) if (state.charAt(num) == "0") break } state = state.substring(0, num) + "1" + state.substring(num + 1, state.length) return false } function getRandom(max) { return Math.round((max - 1) * Math.random()) } // -- End Hiding Here </script> <body onLoad="startBanner()">
