idt=window.setTimeout("www_helpor_net();",1000);
}
//-->

</SCRIPT>

 

4、有影子的数字时钟
  说明： 这个时钟是有影子的，而且还在不停地走着呢 
  代码：
<div id="bgclockshade" style="position:absolute;visibility:visible;font-family:'Arial black';color:#cccccc;font-size:20px;top:50px;left:173px"></div>
<div id="bgclocknoshade" style="position:absolute;visibility:visible;font-family:'Arial black';color:#000000;font-size:20px;top:48px;left:170px"></div>

number(date)
document.write("日")
//-->
</script>

 

6、打字效果
  说明: 文字在状态栏上从左往右一个一个地显示，就象你打出的字一样 
  代码: <script language="JavaScript">
var msg = "欢迎光临，请多提意见。谢谢! " ;
var interval = 120
var spacelen = 120;
var space10=" ";
var seq=0;
function Helpor_net() {
len = msg.length;
window.status = msg.substring(0, seq+1);
seq++;
if ( seq >= len ) {
seq = 0;
window.status = '';
window.setTimeout("Helpor_net();", interval );
}
else
window.setTimeout("Helpor_net();", interval );
}
Helpor_net();
</script>

 

7、文字从左往右移动
  说明: 文字在状态栏上从右往左显示，而且是循环的 
  代码:
<script>
<!--
function Helpor_net(seed)
{ var m1 = "欢迎来到网页特效世界，请多提意见。谢谢! !" ;
var m2 = "" ;
var msg=m1+m2;
var out = " ";
var c = 1;
var speed = 120;
if (seed > 100)
{ seed-=2;
var cmd="Helpor_net(" + seed + ")";
timerTwo=window.setTimeout(cmd,speed);}
else if (seed <= 100 && seed > 0)
{ for (c=0 ; c < seed ; c++)
{ out+=" ";}
out+=msg; seed-=2;
var cmd="Helpor_net(" + seed + ")";
window.status=out;
timerTwo=window.setTimeout(cmd,speed); }
else if (seed <= 0)
{ if (-seed < msg.length)
{
out+=msg.substring(-seed,msg.length);
seed-=2;
var cmd="Helpor_net(" + seed + ")";
window.status=out;
timerTwo=window.setTimeout(cmd,speed);}
else { window.status=" ";
timerTwo=window.setTimeout("Helpor_net(100)",speed);
}
}
}
Helpor_net(100);
-->
</script>

 

8、图像自动变化
  说明: 把一张图片变形扭曲成各种不同的长宽，非常好玩 
  代码:
<img src="http://code.helpor.net/picture/swimming.gif" name="u" border="1" alt="很好玩的">
<script language="JavaScript">

var b = 1;
var c = true;

function www_helpor_net(){
if(document.all);

if(c == true) {
b++;
}
if(b==100) {
b--;
c = false
}

if(b==10) {
b++;
c = true;
}

if(c == false) {
b--;
}
u.width=150 + b;
u.height=125 - b;
setTimeout("www_helpor_net()",50);
}
www_helpor_net();
</script>

10、图片渐渐显隐
  说明: 图片渐渐显隐
  代码: <img src="http://code.helpor.net/picture/swimming.gif" name="u" border="1" style="filter:alpha(opacity=0)">
<script language="JavaScript">

var b = 1;
var c = true;

function helpor_net(){
if(document.all);

if(c == true) {

}

if(c == false) {
b--;
}
u.filters.alpha.opacity=0 + b;
setTimeout("helpor_net()",50);
}
helpor_net();
</script>

 

11、图片渐渐显示
  说明: 图片渐渐显示
  代码:
<img src="http://code.helpor.net/picture/swimming.gif" border="1" id="helpor_net" style="visibility:hidden; FILTER:revealTrans(Duration=4.0, Transition=23);">
<SCRIPT FOR="window" EVENT="onLoad" LANGUAGE="vbscript">

12、自由移动的图片 
  说明: 自由移动的图片
  效果: 看到了吗？
  代码:
<div id="helpor_net" style="position:absolute; visibility:visible; left:0px; top:0px; z-index:-1">
<img src="http://code.helpor.net/picture/swimming.gif" border="0">
</div>
<SCRIPT LANGUAGE="JavaScript">
<!--
var isNS = ((navigator.appName == "Netscape") && (parseInt(navigator.appVersion) >= 4));
var _all = '';
var _style = '';
var wwidth, wheight;
var ydir = '++';
var xdir = '++';
var id1, id2, id3;
var x = 1;
var y = 1;
var x1, y1;

13、随鼠标触动而变化
  说明: 鼠标接触或者离开图片时，图片大小会相应变化

<span id="s1" style = "width : 150"><a href="http://www.helpor.net" target="_blank" onmouseover="www_helpor_net.style.width='200';" onmouseout="www_helpor_net.style.width= '150';"><Img src="http://code.helpor.net/picture/swimming.gif" id="www_helpor_net"></a></span>

 

14、javascript的容错脚本
  说明: javascript的容错脚本，有了它，你的页面就不会出现错误提示了。 
  代码:
<SCRIPT LANGUAGE="JavaScript">
<!--
function Helpor_net() {
return true;
}
window.onerror = Helpor_net();
// -->
</SCRIPT>
