1、逐隐逐现的的特效
逐隐逐现的文字特效[推荐使用][适用于IE4++]
（修改显示的文字后根据说明进行共2步）
1、以下代码放在一个新建页面的HTML的<body></body>区即可：[页面上必须什么都没有]
<html>
<head>
<TITLE>特效</TITLE>
</head>
<script language=javaScript>
<!-- //
var thissize=20
var textfont="隶书"
var textcolor= new Array()

textcolor[3]="111111"
textcolor[4]="222222"
textcolor[5]="333333"
textcolor[6]="444444"
textcolor[7]="555555"
textcolor[8]="666666"
textcolor[9]="777777"

message[3]="javascript源码大全"
i_message=0
var i_strength=0
var i_message=0
var timer
function glowtext() {
if(document.all) {
if (i_strength <=17) {
glowdiv.innerText=message[i_message]
document.all.glowdiv.style.filter="glow(color="+textcolor[i_strength]+", strength=4)"
i_strength++
timer=setTimeout("glowtext()",100)
}
else {
clearTimeout(timer)
setTimeout("deglowtext()",1500)
}
}
}function deglowtext() {
if(document.all) {
if (i_strength >=0) {
glowdiv.innerText=message[i_message]
document.all.glowdiv.style.filter="glow(color="+textcolor[i_strength]+", strength=4)"
i_strength--
timer=setTimeout("deglowtext()",100)
}
else {
clearTimeout(timer)
i_message++
if (i_message>=message.length) {i_message=0}
i_strength=0
intermezzo()
}
}
}
function intermezzo() {
glowdiv.innerText=""
setTimeout("glowtext()",1500)
}
//-->
</script>
<body bgcolor="#000000" onLoad="glowtext()"> //不要忘记写
<div id="glowdiv" style="position:absolute;visibility:visible;600px;text-align:center;
top:150px;left:50px;font-family:隶书;font-size:30pt;color:000000"></div>
</body>
</html>
2、[可选项]修改<div>标签内的代码可以确定文字显示的位置，颜色和大小。
top是距离屏幕上面的距离，left是距离坐侧的距离。font-size是文字大小，
color是颜色。width是DIV层的宽度。由于文字是用DIV来控制的，所以在DIV的宽度范围内不能有其它内容。DIV的位置用绝对位置(position:absolute)表示。
2、超酷的文字特效
超酷的文字特效[特别推荐][共2步]
1、将以下代码加入HEML的<head></head>之间：
<script>
<!--//

function handlerMM(e){
x = (document.layers) ? e.pageX : event.clientX
y = (document.layers) ? e.pageY : event.clientY
}
function ringup() {
if (document.all) {
thisx = x
thisy = y
ringup2()
}
}
function ringup2() {
if (i_fontsize<=1000) {
document.all.ring.style.fontSize=i_fontsize
document.all.ring.style.color="rgb(255,"+Math.floor(i_fontsize/6)+","+Math.floor(i_fontsize/6)+")"
document.all.ring.style.posLeft=thisx-(Math.floor(i_fontsize/3))
document.all.ring.style.posTop=thisy-(Math.floor(i_fontsize/1.4))
step+=4
i_fontsize+=step
timer=setTimeout("ringup(2)",50)
}
else {
clearTimeout(timer)
i_fontsize=0
step=0
document.all.ring.style.posTop=-10000
}
}
document.onmousemove = handlerMM;
//-->
</script>

font-size:20pt;
font-family:Times;
}
</style>
2、将以下代码加入HEML的<body></body之间>
<div id="ring" class="ringstyle">
<p><font color="#FF8080">:-)</font></p>
</div><div id="redirection" class="explain">
<p>移动你的鼠标到这里来看看<a target="_blank" onMouseOver="ringup()"

//-->
</script>
6、打字时候的特效
打字效果的文字特效[修改显示的文字即可]
[根据下面的说明进行共1步]
1、以下代码放在HTML的<body></body>之间[适当的位置]：
<script language=javascript>
var layers =document.layers,style=document.all,both=layers||style,idme=908601;
if(layers){layerRef='document.layers';styleRef ='';}if(style){layerRef='document.all';styleRef =
'.style';}
function writeOnText(obj,str){
if(layers)with(document[obj]){ document.open();document.write(str);document.close();}
if(style)eval(obj+'.innerHTML=str'); }
var dispStr=new Array("javascript源码大全");
var overMe=0;
function txtTyper(str,idx,idObj,spObj,clr1,clr2,delay,plysnd){
var tmp0=tmp1= '',skip=100;
if (both && idx<=str.length) {
if (str.charAt(idx)=='<'){ while(str.charAt(idx)!='>') idx++;idx++;}
if (str.charAt(idx)=='&'&&str.charAt(idx+1)!=' '){ while (str.charAt(idx)!= ';')idx++;idx++;}
tmp0 = str.slice(0,idx);
tmp1 = str.charAt(idx++);
if (overMe==0 && plysnd==1){
if (navigator.plugins[0]){
if(navigator.plugins["LiveAudio"][0].type=="audio/basic" && navigator.javaEnabled()){document.embeds
[0].stop();
setTimeout("document.embeds[0].play(false)",100);}
} else if (document.all){
ding.Stop();
setTimeout("ding.Run()",100);}
overMe=1;}else overMe=0;
writeOnText(idObj, "<span class="+spObj+"><font color='"+clr1+"'>"+tmp0+"</font><font color='"+clr2
+"'>"+tmp1+"</font></span>");
setTimeout("txtTyper('"+str+"', "+idx+", '"+idObj+"', '"+spObj+"', '"+clr1+"', '"+clr2+"', "+delay+" ,"+plysnd+")",delay);}}
function init(){txtTyper(dispStr[0], 0, 'ttl0', 'ttl1', '#339933', '#99FF33', 300, 0);}
</script>
<BODY onload=init()>
<DIV class=ttl1 id=ttl0></DIV>
</BODY>
7、淡入淡出文字特效
淡入淡出的文字效果[根据下面的说明进行共3步]
1、以下代码放在HTML的<head></head>之间：
<script language="javaScript">
<!--
function checkBrowserForVersion4(){
var x=navigator.appVersion;
y=x.substring(0,4);
if(y>=4) Effect();}
var isNav=(navigator.appName.indexOf("Netscape")!=-1);
var colors=new Array
("FFFFFF","FFFFFF","FFFFFF","FFFFFF","FFFFFF","FFFFFF","FFFFFF","F9F9F9","F1F1F1","E9E9E9","E1E1E1","D9D9D9","D1D1D1","C9C9C9","C1C1C1","B9B9B9","B1B1B1","A9A9A9","A1A1A1","999999","919191","898989","818181","797979","717171","696969","616161","595959","515151","494949","414141","393939","313131","292929","212121","191919","111111","090909","000000")
a=0,b=1
function Effect(){
color=colors[a];
//*改改下面的文字内容即可,可使用HTML语法，但是注意引号不要混用。双引号内是单引号。*//
aa="<font size='5'><font face='Arial, Helvetica, sans-serif'><font color="+color+">Save page and Get Code !<p>Enjoy All These Free Javascripts ......</font></font></font>"
if(isNav) {document.object1.document.write(aa);document.object1.document.close();}
else object1.innerHTML=aa
a+=b;if (a==38) b-=2;if (a==0) b+=2;xx=setTimeout("Effect()",10);}
//-->
</script>
2、以下代码放在HTML的<body></body>之间[适当的位置]：
<body onload="checkBrowserForVersion4()" >
<div id="object1" style="position:absolute; visibility:show; left:181px; top:113px; z-index:2"></div>
3、特别说明：只要改变上面的TOP值和LEFT值即可确定文字显示的绝对位置。TOP表示文字距离屏幕顶部的距离（象素），LEFT是离屏幕左侧的距离。上面有一大堆乱七八糟的字符是确定渐变的颜色数组。
8、炽热文字的特效
炽热文字的特殊效果[适用于IE4++]
（根据下面的说明进行共3步）
1、将以下代码加入HEML的<head></head>之间：
<style>
<!--
#glowtext{
filter:glow(color=red,strength=2);
100%;
}
-->
</style>
<script language="JavaScript1.2">
function glowit(which){
if (document.all.glowtext[which].filters[0].strength==2)
document.all.glowtext[which].filters[0].strength=1
else
document.all.glowtext[which].filters[0].strength=2
}
function glowit2(which){
if (document.all.glowtext.filters[0].strength==2)
document.all.glowtext.filters[0].strength=1
else
document.all.glowtext.filters[0].strength=2
}
function startglowing(){
if (document.all.glowtext&&glowtext.length){
for (i=0;i<glowtext.length;i++)
eval('setInterval("glowit('+i+')",150)')
}
else if (glowtext)
setInterval("glowit2(0)",150)
}
if (document.all)
window.onload=startglowing
</script>
2、将以下代码加入到HEML的<body></body>之间[适当的位置]：
<span id="glowtext">这里是要显示的文字</span>
3、[可选项]改变文字颜色和背景色可以得到不同的效果。文字颜色修改，只要修改filter:glow(color=red,strength=2); 中的color项,strength为颜色的深度值 。
9、状态栏文字特效
状态栏中的文字[修改显示的文字后复制到<body></body>]
<script language=JavaScript>
var MESSAGE="javascript源码大全"
var POSITION=100
var DELAY=5
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>
