我不知道如何处理这个问题。我希望能够执行以下操作:我有一个链接到另一个页面的文件夹的图标。当用户单击图标而不是转到页面时,文件夹图标下方会显示一个子文件夹,当用户单击其中一个文件夹时,它会将用户定向到该页面。
以下是我所做的:
<h4>
<a href="CalMediConnect_DMgmt.cfm">
<img src="images/folder-documents-icon32.jpg" alt="Custodial" class="float-left">
Disease Management
</a>
</h4>
<br /><br />
更新
我尝试了以下操作,似乎无法正常工作:
以下是脚本:
var tree = document.querySelectorAll('ul.tree a:not(:last-child)');
for(var i = 0; i < tree.length; i++) {
tree[i].addEventListener('click', function(e) {
var parent = e.target.parentElement;
var classList = parent.classList;
if(classList.contains("open")) {
classList.remove('open');
var opensubs = parent.querySelectorAll(':scope .open');
for(var i = 0; i < opensubs.length; i++) {
opensubs[i].classList.remove('open');
}
} else {
classList.add('open');
}
});
}
以下是CSS:
ul.tree li {
list-style-type: none;
position: relative;
}
ul.tree li ul {
display: none;
}
ul.tree li.open > ul {
display: block;
}
ul.tree li a {
color: #4284B0;
text-decoration: none;
}
ul.tree li a:before {
height: 1em;
padding: .1em;
font-size: .8em;
display: block;
position: absolute;
left: -1.3em;
top: .2em;
}
.margin-left {
margin-left: -15px;
}
HTML:
<ul class="tree margin-left">
<li>
<h4>
<a href="#">
<img src="images/folder-documents-icon32.jpg" alt="Custodial" class="float-left">
Disease Management
</a>
</h4>
<ul>
<li>
<h5>
<a href="CalMediConnect_DMgmt.cfm">
<img src="images/folder-documents-icon32.jpg" alt="Custodial" class="float-left">
Disease Management
</a>
</h5>
</li>
</ul>
</li>
</ul>
任何帮助都将不胜感激。

这是一个使用jQuery构建的基本示例...
https://jsfiddle.net/kennethcss/8b4e6o42/
$('.folder').on('click', function(e) {
var folder = $(this).find('.sub-folder');
if (e.target !== this) return;
if(folder.hasClass('hidden')) {
folder.removeClass('hidden');
} else {
folder.addClass('hidden');
}
});
&#13;
.folder {
cursor: pointer;
}
.hidden {
display: none;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<ul class="container">
<li class="folder">Primary
<ul class="sub-folder hidden">
<li>Secondary</li>
<li>Secondary</li>
<li>Secondary</li>
</ul>
</li>
<li class="folder">Primary
<ul class="sub-folder hidden">
<li>Secondary</li>
<li>Secondary</li>
<li>Secondary</li>
</ul>
</li>
<li class="folder">Primary
<ul class="sub-folder hidden">
<li>Secondary</li>
<li>Secondary</li>
<li>Secondary</li>
</ul>
</li>
</ul>
&#13;
当然,你可以随心所欲地设计风格;这个例子只是演示了如何构建HTML,CSS和JS来创建一个简单的文件夹结构。
