dn001

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TOM科技";
  var m3 = "请多提意见,谢 谢! ";
  var m4 = "欢迎您下次再来! ";
  var m5 = "http://tech.tom.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TOM科技,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  {out += msg.charAt(i)}
  for (i=1;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TOM科技学园,(http://tech.tom.com/software/)这里有许多电脑应用方面的文章,是您学习电脑的好去处!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TOM科技学园! "
  ar[1] = "它是您学校电脑的好帮手! "
  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TOM科技(http://tech.tom.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"〉

  var Message="欢迎光临TOM科技(http://tech.tom.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:

特效七:状态栏固定信息

〈body bgcolor="#fef4d9" onmouseover="self.status='欢迎光临“TOM科技”--http://tech.tom.com';return true"〉
