步骤 1: 将下面代码加到 <head> 标签内:
复制代码 代码如下:
<script type="text/javascript">
/***********************************************
* DHTML slideshow script- © Dynamic Drive DHTML code library (www.dynamicdrive.com)
* This notice must stay intact for legal use
* Visit http://www.dynamicdrive.com/ for full source code
***********************************************/
var photos=new Array()
var photoslink=new Array()
var which=0
//define images. You can have as many as you want:
photos[0]="photo1.jpg"
photos[1]="photo2.jpg"
photos[2]="photo3.jpg"
//Specify whether images should be linked or not (1=linked)
var linkornot=0
//Set corresponding URLs for above images. Define ONLY if variable linkornot equals "1"
photoslink[0]=""
photoslink[1]=""
photoslink[2]=""
//do NOT edit pass this line
var preloadedimages=new Array()
for (i=0;i<photos.length;i++){
preloadedimages[i]=new Image()
preloadedimages[i].src=photos[i]
}
function applyeffect(){
if (document.all && photoslider.filters){
photoslider.filters.revealTrans.Transition=Math.floor(Math.random()*23)
photoslider.filters.revealTrans.stop()
photoslider.filters.revealTrans.apply()
}
}
function playeffect(){
if (document.all && photoslider.filters)
photoslider.filters.revealTrans.play()
}
function keeptrack(){
window.status="Image "+(which+1)+" of "+photos.length
}
function backward(){
if (which>0){
which--
applyeffect()
document.images.photoslider.src=photos[which]
playeffect()
keeptrack()
}
}
function forward(){
if (which<photos.length-1){
which++
applyeffect()
document.images.photoslider.src=photos[which]
playeffect()
keeptrack()
}
}
function transport(){
window.location=photoslink[which]
}
</script>
步骤 2: 将下面代码加到需要的地方:
复制代码 代码如下:
<table border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="100%" colspan="2" height="22"><center>
<script>
if (linkornot==1)
document.write('<a href="javascript:transport()">')
document.write('<img src="'+photos[0]+'" name="photoslider" style="filter:revealTrans(duration=2,transition=23)" border=0>')
if (linkornot==1)
document.write('</a>')
</script>
</center></td>
</tr>
<tr>
<td width="50%" height="21"><p align="left"><a href="#" onClick="backward();return false">Previous Slide</a></td>
<td width="50%" height="21"><p align="right"><a href="#" onClick="forward();return false">Next Slide</a></td>
</tr>
</table>
<p align="center"><font face="Arial" size="-2">Free DHTML scripts provided by<br>
