偶然发现TreeTable有问题......
有助于理解,当检查上部td输入时,如何使第二级和更低级别不会出现。不幸的是我只能使用HTML + CSS。 how it looks like now on jsfiddle
<table class="table-tree" cellspacing="0">
<tr>
<td>
<label for="folder2">Folder 1</label>
<input type="checkbox" id="folder2" />
<table class="table-wrapper">
<tr>
<td class="file"><a href="">Subfile 1</a></td>
<td class="file"><a href="">Subfile 2</a></td>
<td>
<label for="folder3">Subfolder 1</label>
<input type="checkbox" id="folder3" />
<table class="table-wrapper">
<tr>
<td class="file"><a href="">Subsubfile 1</a></td>
<td class="file"><a href="">Subsubfile 2</a></td>
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>
</table>
如果布局像这样,那就太棒了
有人可以帮助我吗?

您需要在中table
(或ul
)和ol
替换td
li
(删除tr
) HTML 和 CSS ,它看起来就像图像上的病态布局。
执行此操作的另一个原因是您显示的内容不是表格数据,而是文件列表,因此您不应使用表格而是列表类型布局。

你的CSS有两个错误。
首先,您应该选择未选中的复选框,如下所示:
input:not(:checked)
并且不依赖于规则申请中的后备。
第二个也是更重要的是,规则td input:checked + table > tbody td
是错误的。
事实上,如果您选中了外部复选框但未嵌套嵌套,则该规则仍将匹配嵌套表td,因为第一部分td input:checked + table > tbody
匹配外部表体,然后第二部分td
匹配寻找具有祖先的那个身体的td。
你应该检查直接的孩子。
总结一下,你可以把你的css改成这样的东西:
*, html {
font-family: Verdana, Arial, Helvetica, sans-serif;
}
body, form, ul, li, p, h1, h2, h3, h4, h5 {
margin: 0;
padding: 0;
}
body {
background-color: #fafafa;
color: rgba(0, 0, 0, 0.7);
margin: 0;
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
/**
* Tree Table CSS
**/
.table-tree {
display: block;
padding: 30px 0 0 30px;
}
td {
display: block;
position: relative;
}
td label {
background: url(http://www.webmasters.by/images/articles/css-tree/folder-horizontal.png) 15px 1px no-repeat;
cursor: pointer;
display: block;
padding-left: 37px;
width: 100%;
}
td input {
position: absolute;
left: 0;
margin-left: 0;
opacity: 0;
z-index: 2;
cursor: pointer;
height: 1em;
width: 1em;
top: 0;
}
// CHANGED HERE
td input:not(:checked) + table {
background: url(http://www.webmasters.by/images/articles/css-tree/toggle-small-expand.png) -3px -1px no-repeat;
margin: -0.938em 0 0 0;
height: 1em;

}
td input:checked + table {

display: block;
margin: -1.25em 0 0 -44px;
padding: 1.25em 0 0 80px;
height: auto;
width: 100%;
}
td.file {
margin-left: -1px !important;
}
// CHANGED HERE

始终使用最具体的CSS规则,因为当HTML变得庞大时,您可能会有一些惊喜。
