我可以让图像循环浏览，但现在当我点击“上一个”或“下一个”链接时，每次我存储图像的文件夹都会弹出。你知道为什么会发生这种情况或者如何阻止它吗

脚本

<script type="text/javascript">

为所有图像div添加索引（1-5），如：

<div id="image1" style="display:block">

更改循环中的索引，并使everywhere

1-5

。或者将所有内容更改为

0-4

为所有图像div添加索引（1-5），如：

<div id="image1" style="display:block">

更改循环中的索引，并使everywhere

1-5

。或者将所有图像容器都更改为

0-4

<div id="image" style="display:none">

具有相同的id且与格式图像不对应#

还可以将以下循环从

for (var i=0; i < 5; ++i) {
     document.getElementById("image"+i).style.display = "none";
    }

for（变量i=0；i<5；++i）{
document.getElementById（“image”+i）.style.display=“无”；
}

到

for（变量i=0；i<5；++i）{
document.getElementById（“image”+（i+1））.style.display=“无”；
}

所有图像容器

<div id="image" style="display:none">

具有相同的id且与格式图像不对应#

还可以将以下循环从

for (var i=0; i < 5; ++i) {
     document.getElementById("image"+i).style.display = "none";
    }

for（变量i=0；i<5；++i）{
document.getElementById（“image”+i）.style.display=“无”；
}

到

for（变量i=0；i<5；++i）{
document.getElementById（“image”+（i+1））.style.display=“无”；
}

我通过在每个图像容器中添加1,2,3,4实现了这一点
