我到处搜索答案并找到了类似的问题示例，但答案不适用于我的情况。事实上，我是新手，因此我不具备将找到的答案应用到我的问题中的技能。
问题:
我有一个 Div，当单击缩略图时，Div 图像会通过 JavaScript/jQuery 脚本替换为另一个图像(我不确定是否有人可以澄清)。这工作正常，但问题是页面滚动回顶部，然后用户必须向下滚动才能看到替换后的图像。
我在网上查看并发现 return false: 在 JavaScript 中可能有帮助，但我已经查看并返回 false 已经存在。
我考虑使用的另一个选项是基于 JavaScript cookie 的解决方案，其中发送 cookie，浏览器滚动位置通过读取 cookie 来保持，但是我似乎无法使该解决方案起作用，我认为问题所在可能是因为我在本地托管但我可能错了...
第三种是使用 PHP 脚本，但我还没有找到关于此方法的明确答案，这也意味着我将不得不学习 PHP(我确信无论如何我都必须及时学习)。
这是 JavaScript:
<script type="text/javascript">
$(document).ready(function() {
$('.galleryicon').live("click", function() {
$('#mainImage').hide();
$('#cakebox').css('background-image', "url('ajax-loader.gif')");
var i = $('<img />').attr('src',this.href).load(function() {
$('#mainImage').attr('src', i.attr('src'));
$('#cakebox').css('background-image', 'none');
$('#mainImage').fadeIn();
});
return false;
});
});
</script>
这是 html:
<div class="cakecont">
<div id="cakebox">
<img src="../images/cakes/babycake1.png" alt="Main Image" id="mainImage"/>
<div class="pageinfo2">
<h3>Cake Type 1</h3>
<h6>£2.00</h6>
</div>
<div class="infobox">
<h6> Description </h6>
</div>
<div class="gallerybox">
<a href="../images/cakes/babycaketop.png" class="galleryicon">
<img src="../images/thumbs/babycaketopsml.png" alt="Thumbnail 2"/></a>
<a href="../images/cakes/babycake1.png" class="galleryicon">
<img src="../images/thumbs/babycakesml.png" alt="Image 1"/></a>
</div>
</div>
</div>

我试图自己解决这个问题。到目前为止，这是我不得不问的第一个关于我的网站 build 的问题，我所有的学习和对过去问题的补救措施都是由谷歌提供的，这个问题已经逃避了我的搜索引擎技能。
下面我添加了页面的所有 html，以防其他脚本覆盖"new"修改后的 JavaScript -

最佳答案
可以保存当前的滚动量，以后再设置:
var tempScrollTop = $(window).scrollTop();
..//Your code
$(window).scrollTop(tempScrollTop);
