1、不停闪烁的图像

不停闪烁的图片[修改显示的图片及链接地址后根据说明进行共1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>Blink image</TITLE>
</HEAD>
<BODY ONLOAD="soccerOnload()" topmargin="0">
<DIV  >
<a href="http://图片的链接.com" target="_blank">
<IMG SRC="要显示的图片.gif" ></a>
</DIV>
<SCRIPT LANGUAGE="JavaScript">
var msecs = 500; //改变时间得到不同的闪烁间隔；
var counter = 0; 
function soccerOnload() {
setTimeout("blink()", msecs);
}
function blink() {
soccer.style.visibility =
(soccer.style.visibility == "hidden") ? "visible" : "hidden";
counter +=1;
setTimeout("blink()", msecs);
}
</SCRIPT>
</BODY>
</HTML>

2、图片展示选择

　 
图片展示选择[很棒的图片展示脚本所有图片尺寸应该一致才好]

1、以下代码放在HTML的<body></body> 区即可：

<CENTER>
<img width=200 height=223 src="图片名字.jpg" name="x1">
</CENTER>
//以上是程序初始时显示的图片。
<FORM>
<CENTER>
<SELECT onChange="document.x1.src=options[selectedIndex].value">
<option value="图片名字1.jpg">看看图片1</option>
<option value="图片名字2.jpg">看看图片2</option>
<option value="图片名字3.jpg">看看图片3</option>
<option value="图片名字4.jpg">看看图片4</option>
</SELECT>
</CENTER>
</FORM>

3、图片的渐现播放

　 
图片的渐显播放[推荐][根据下面的说明进行共3步，修改图片的名称及路径即可]
第三步的top:120px;left:240px可以设定显示的位置

====1、将下面的代码插入到HEML的<head></head>之间： 

<script language=javaScript>
<!--//
sandra0 = new Image();
sandra0.src = "image1.gif";
sandra1 = new Image();
sandra1.src = "image2.gif";
sandra2 = new Image();
sandra2.src = "image3.gif";
var i_strngth=1
var i_image=0
var imageurl = new Array()
imageurl[0] ="图片名称1.gif"
imageurl[1] ="图片名称2.gif"
imageurl[2] ="图片名称3.gif"
function showimage() { 
if(document.all) {
if (i_strngth <=110) {
testimage.innerHTML="<img +i_strngth+")' src="+imageurl[i_image]+" ;
i_strngth=i_strngth+10
var timer=setTimeout("showimage()",100)
}
else {
clearTimeout(timer)
var timer=setTimeout("hideimage()",1000)
}
}
if(document.layers) {
clearTimeout(timer)
document.testimage.document.write("<img src="+imageurl[i_image]+" )
document.close()
i_image++
if (i_image >= imageurl.length) {i_image=0} 
var timer=setTimeout("showimage()",2000)
} 
}
function hideimage() { 
if (i_strngth >=-10) {
testimage.innerHTML="<img +i_strngth+")' src="+imageurl[i_image]+" ;
i_strngth=i_strngth-10
var timer=setTimeout("hideimage()",100)
} 
else {
clearTimeout(timer)
i_image++
if (i_image >= imageurl.length) {i_image=0}
i_strngth=1
var timer=setTimeout("showimage()",500) 
}
}
//-->
</script>

====2、修改<body>语句为：

<body onLoad="showimage()">

====3、将下面的代码加入到HEML的<body></body>之间：

<div ></div>

4、将图片固定在左上角

　 
将图片图片固定在页面左上角[根据说明修改即可共1步]

1、将以下代码加入到HEML的<body></body>之间

<SCRIPT language=JavaScript>
<!-- Hide the script from old browsers --
// 1) 做一个88*31的LOGO。
if (document.images)
var staticlogo=new Image(88,31)
// 2) 设置LOGO的路径。
staticlogo.src="图片的名称1.gif"
// 3) 以下是LOGO代表的连接。
var logolink="http://www.happydrips.com"
// 4) 设置ALT属性。
var alttext="快乐点滴"
// 5) 设置下列属性为 1或者0(1是IE特有的，使LOGO隐现）
var fadeintoview=1
/* 6) 最后设置LOGO显示的时间，例如12 秒，数值为0表示一直显示
*/
var visibleduration=12
/////////////////////////以下不要改变/////////////////////////
function regenerate(){
window.location.reload()
}
function regenerate2(){
if (document.layers)
setTimeout("window.onresize=regenerate",400)
}
var fadeset=''
if (fadeintoview)
fadeset="filter:alpha(opacity=0)"
if (document.all)
document.write('<span ></span>')
function bringintoview(){
if (logo.filters.alpha.opacity<=95)
logo.filters.alpha.opacity+=5
else{
clearInterval(viewit)
if (visibleduration!=0)
setTimeout("logo.style.visibility='hidden'",visibleduration*1000)
}
}
function createlogo(){
staticimage=new Layer(100)
staticimage.left=-300
staticimage.top=120
staticimage.document.write('<a href="'+logolink+'"><img src="'+staticlogo.src+'" '+alttext+'"></a>')
staticimage.document.close()
staticimage.visibility="show"
regenerate2()
staticitns()
}
if (document.layers)
window.onload=createlogo;
if (document.all){
w=2
h=2
logo.style.left=w
logo.style.top=h
}
function logoit(){
var w2=document.body.scrollLeft+w
var h2=document.body.scrollTop+h
logo.style.left=w2
logo.style.top=h2
}
function logoit2(){
staticimage.left=pageXOffset+2
staticimage.top=pageYOffset+2
}
function insertimage(){
logo.innerHTML='<a href="'+logolink+'"><img src="'+staticlogo.src+'" '+alttext+'"></a>'
if (fadeintoview)
viewit=setInterval("bringintoview()",100)
else{
if (visibleduration!=0)
setTimeout("logo.style.visibility='hidden'",visibleduration*1000)
}
}
if (document.all){
window.onscroll=logoit
window.onresize=new Function("window.location.reload()")
window.onload=insertimage
}
function staticitns(){
setInterval("logoit2()",90)
if (visibleduration!=0)
setTimeout("staticimage.visibility='hide'",visibleduration*1000)
}
//--> 
</SCRIPT>

5、左右移动的图片

左右移动的图片[修改图片名称即可][共2步]

1、将以下代码加入到HEML的<head></head>之间：

<script LANGUAGE="JavaScript"><!--
step = 0;
obj = new Image();
function anim(xp,xk,smer) //smer = direction
{
obj.style.left = x;
x += step*smer;
if (x>=(xk+xp)/2) {
if (smer == 1) step--;
else step++;
}
else {
if (smer == 1) step++;
else step--;
}
if (x >= xk) {
x = xk;
smer = -1;
}
if (x <= xp) {
x = xp;
smer = 1;
}
// if (smer > 2) smer = 3;
setTimeout('anim('+xp+','+xk+','+smer+')', 50);
}
function moveLR(objID,movingarea_width,c)
{
if (navigator.appName=="Netscape") window_width = window.innerWidth;
else window_width = document.body.offsetWidth;
obj = document.images[objID]; 
image_width = obj.width;
x1 = obj.style.left;
x = Number(x1.substring(0,x1.length-2)); // 30px -> 30
if (c == 0) {
if (movingarea_width == 0) {
right_margin = window_width - image_width;
anim(x,right_margin,1);
}
else {
right_margin = x + movingarea_width - image_width; 
if (movingarea_width < x + image_width) window.alert("No space for moving!");
else anim(x,right_margin,1);
}
}
else {
if (movingarea_width == 0) right_margin = window_width - image_width;
else {
x = Math.round((window_width-movingarea_width)/2);
right_margin = Math.round((window_width+movingarea_width)/2)-image_width;
}
anim(x,right_margin,1);
} 
} 
//--></script>
2、将以下代码加入到HEML的<body></body>之间：

<img src="要显示的图片名称.gif" name="picture"
  WIDTH="140" HEIGHT="40">
<script LANGUAGE="JavaScript"><!--
setTimeout("moveLR('picture',300,1)",10);
//--></script>
