实现网页状态栏特效全攻略
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
for (i=1;i
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〉
