问题描述
我想知道你如何做一个背景幻灯片淡出到其他照片像一个普通的幻灯片。我试过很多codeS和尚未成功。
I was wondering how you make a background slideshow fade into other photos like a regular slideshow. I've tried many codes and have yet to be successful.
现在，我有一个code使背景更改为不同的照片效果很好，但它不褪色。反正有添加此？
Now, I have a code to make the background change to different photos which works well, but it doesn't fade. Is there anyway to add this?
下面是code
<html>
<head>
<style>
body{
/*Remove below line to make bgimage NOT fixed*/
background-attachment:fixed;
background-repeat: no-repeat;
background-size: cover;
/*Use center center in place of 300 200 to center bg image*/
background-position: 0 0; background-
}
</style>
<script language="JavaScript1.2">

bgslides[1]="http://i892.photobucket.c…
bgslides[2]="http://i892.photobucket.c…
//Specify interval between slide (in miliseconds)
var speed=2000
//preload images
var processed=new Array()
for (i=0;i<bgslides.length;i++){
processed[i]=new Image()
processed[i].src=bgslides[i]
}
var inc=-1
function slideback(){
if (inc<bgslides.length-1)
inc++
else
inc=0
document.body.background=processed[inc…
}
if (document.all||document.getElementById)
window.onload=new Function('setInterval("slideback()",spee…
</script>
</head>
</html>
如果您有任何建议，请让我知道。另外，我不是在编码上最伟大，没有关于JavaScript的线索，所以请解释一下该怎么做。
If you have any suggestions please let me know. Also, I am not the greatest at coding and don't have a clue about JavaScript, so please explain what to do.
