LZ是想做到什么?代码太长还没看
[解决办法]
问楼主，怎么个替换法？
[解决办法]

[解决办法]
反应慢
[解决办法]
lz要问什么？
[解决办法]
明白了
[解决办法]
太长了，没敢看，楼猪想干吗？
[解决办法]
[解决办法]
图片名有规律点不用这么麻烦吧?
[解决办法]
原来楼主是要从数据库取数据给数组ProdPicList赋值……
[解决办法]
是用我说的方法么？
口水。。。。。。。。。
[解决办法]
我要显示的图片有多少是不一定的 所以这样写死这个数组并给个固定的值应用中意义不大 所有替换为从数据库中取啊
===================================================================================
我在LZ另外一个贴上说的方法不知道LZ试过没有
前台放个隐藏的listbox,在后台绑定text属性为你数据库里图片的路径名.
前台这样取:
<script language= "javascript ">
<!--
var ProdPicList=new Array(); //定义一个JS数组 我忘了要不要声明数组个数了
var list=document.getElementById( "ListBox1 ");//list对象就是你绑定的listbox
var listindex=list.length;
for(int i=0;i <listindex-1;i++)
{
ProdPicList[i]=list.options[i].text;
}
-->
</script>
============================
这样应该是可行的,我晚上有空帮你弄下.
