在上网时我们注意往往是网站页面内容,而状态栏不会被人太多注意,如果我们给页面的状态栏加一些特效,肯定会使你的网站增添一道风景,下面就给大家介绍7种常见的状态栏特效的Javascript代码。 特效一:滚动显示 第一步:把如下代码加入< head>区域中 < script language="Javascript"> < !-- function scrollit(seed) { var m1 = "HI:你好! "; var m2 = "欢迎访问网页教学网"; var m3 = "请多提意见,谢谢! "; var m4 = "欢迎您下次再来!"; var m5 = "www.webjx.com "; var msg=m1+m2+m3+m4+m5; var out = " "; var c = 1; if (seed > 100) { seed--; cmd="scrollit("+seed+")"; timerTwo=window.setTimeout(cmd,100); } else if (seed < = 100 && seed > 0) { for (c=0 ; c < seed ; c++) { out+=" "; } out+=msg; seed--; window.status=out; cmd="scrollit("+seed+")"; timerTwo=window.setTimeout(cmd,100); } else if (seed < = 0) { if (-seed < msg.length) { out+=msg.substring(-seed,msg.length); seed--; window.status=out; cmd="scrollit("+seed+")"; timerTwo=window.setTimeout(cmd,100); } else { window.status=" "; timerTwo=window.setTimeout("scrollit(100)",75); } } } //--> < /script> 第二步:把如下代码加入< body>区域中 < body background=bag.gif onLoad="scrollit(100)"> 特效二:文字从状态栏的右边循环弹出 把如下代码加入< head>区域中 < script language="Javascript"> var MESSAGE = "欢迎来到网页教学网,请多提意见。谢谢! " var POSITION = 150 var DELAY = 10 var scroll = new statusMessageObject() function statusMessageObject(p,d) { this.msg = MESSAGE this.out = " " this.pos = POSITION this.delay = DELAY this.i = 0 this.reset = clearMessage} function clearMessage() { this.pos = POSITION} function scroller() { for (scroll.i = 0; scroll.i < scroll.pos; scroll.i++) { scroll.out += " "} if (scroll.pos >= 0) scroll.out += scroll.msg else scroll.out = scroll.msg.substring(-scroll.pos,scroll.msg.length) window.status = scroll.out scroll.out = " " scroll.pos-- if (scroll.pos < -(scroll.msg.length)) { scroll.reset()} setTimeout ('scroller()',scroll.delay)} function snapIn(jumpSpaces,position) { var msg = scroll.msg var out = "" for (var i=0; i< position; i++) {out += msg.charAt(i)} for (i=1;i< jumpSpaces;i++) {out += " "} out += msg.charAt(position) window.status = out if (jumpSpaces < = 1) { position++ if (msg.charAt(position) == ' ') {position++ } jumpSpaces = 100-position } else if (jumpSpaces > 3) {jumpSpaces *= .75} else {jumpSpaces--} if (position != msg.length) { var cmd = "snapIn(" + jumpSpaces + "," + position + ")"; scrollID = window.setTimeout(cmd,scroll.delay); } else { window.status="" jumpSpaces=0 position=0 cmd = "snapIn(" + jumpSpaces + "," + position + ")"; scrollID = window.setTimeout(cmd,scroll.delay); return false } return true} snapIn(100,0); < /script> 特效三:title弹出效果 把如下代码加入< head>区域中 < script language="javascript"> < !-- Hide me var index_count = 0; var title_string = "欢迎光临网页教学网,(www.webjx.com)这里有许多电脑应用方面的文章 ,是您学习网页制作技术的好去处!希望您能够常来!"; var title_length = title_string.length; var cmon; var kill_length = 0; function loopTheScroll() { scrollTheTitle(); if(kill_length > title_length) { clearTimeout(cmon); } kill_length++; cmon = setTimeout("loopTheScroll();",100) } function scrollTheTitle() { var doc_title = title_string.substring((title_length - index_count - 1),title_length); document.title = doc_title; index_count++; } loopTheScroll(); //--> < /script> 特效四:文字组合弹出 第一步:把如下代码加入< head>区域中 < script language="javascript"> < !-- Hide this script from old browsers -- var speed = 10 var pause = 1500 var timerID = null var bannerRunning = false var ar = new Array() ar[0] = "欢迎来到网页教学网!" ar[1] = "它是您学校网页制作技术的好帮手!" 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> 第二步:把如下代码加入< body>区域中 < body bgcolor="#fef4d9" onLoad="startBanner()"> 特效五:文字不停闪烁 第一步:把如下代码加入< head>区域中 < script language=""> < !-- var yourwords = "欢迎光临网页教学网(www.webjx.com)!!!"; var speed = 700; var control = 1; function flash() { if (control == 1) { window.status=yourwords; control=0; } else { window.status=""; control=1; } setTimeout("flash()",speed); } // --> < /script> 第二步:把如下代码加入< body>区域中 < body bgcolor="#fef4d9" onLoad="flash()"> 特效六:文字来回出现 第一步:把如下代码加入< head>区域中 < script LANGUAGE="Javascript"> < !-- Begin var Message="欢迎光临网页教学网(www.webjx.com)!!!!!"; var place=1; function scrollIn() { window.status=Message.substring(0, place); if (place >= Message.length) { place=1; window.setTimeout("scrollOut()",300); } else { place++; window.setTimeout("scrollIn()",50); } } function scrollOut() { window.status=Message.substring(place, Message.length); if (place >= Message.length) { place=1; window.setTimeout("scrollIn()", 100); } else { place++; window.setTimeout("scrollOut()", 50); } } // End --> < /script> 第二步:把< body>中的内容改为: < body bgcolor="#fef4d9" onLoad="scrollIn()"> 特效七:状态栏固定信息 < body bgcolor="#fef4d9" onmouseover="self.status='欢迎光临“网页教学网”--http://www.webjx.com';return">
