我做了以下。我想点击列表项来切换下一个div。
click
时 list item
,
<li><a href="#">Create/Read/Manipulate</a></li>
下一步 div.submenu
,再次点击隐藏以反映jQuery中的效果切换效果。
<div class="submenu">
<a href="#">DOM</a><br />
<a href="#">Reader/Writer</a><br />
<a href="#">SimpleXML</a><br />
</div>
我不想使用jQuery。欢迎使用纯CSS或JavaScript。
#leftcolumn {
width: 18%;
margin: 3px;
padding: 0;
display: inline;

#leftcolumn ul.leftmenu {
list-style: none;

答案 1 :(得分:1)
正如您特别提到的使用&#39;点击&#39;事件:
您更正后的HTML(仅<li>
个元素是<ul>
或<ol>
元素的有效子元素):
<li>
<input id="demo" type="checkbox" />
<label for="demo">Create/Read/Manipulate</label>
<div id="submenu"> <a href="#">DOM</a>
<br /> <a href="#">Reader/Writer</a>
<br /> <a href="#">SimpleXML</a>
<br />
</div>
</li>
还有其他CSS:
/* to emulate the 'feel' of the other <a> elements: */
label {
cursor: pointer;
}
/* move the checkbox outside of the visual field to hide it: */
li input[id][type="checkbox"] {
position: absolute;
left: -1000px;
top: -1000px;
}
/* styling <div> elements with an [id] attribute that are a subsequent
sibling of an <input> with an [id]: */
input[id] ~ div[id] {
display: none;
}
/* styling the subsequent sibling <div> element of a :checked <input>
that has an [id]: */
input[id]:checked ~ div[id] {
display: block;
}
这使用<input />
元素checkbox
和radio
类型的功能来保留:hover
事件之外的状态,并使用:checked
伪类来基于该状态设置元素。
将相关的<div>
元素置于<li>
内,然后允许使用通用兄弟组合子(~
)根据状态定位<div>
({1}} :checked
/未选中)复选框。
答案 2 :(得分:1)
我找到了两个不同的解决方案,
1。)使用<input/>
类型复选框,
li input[id][type="checkbox"] {
position: absolute;
left: -1000px;
top: -1000px;
}
input[id] ~ div[id] {
display: none;
}
input[id]:checked ~ div[id] {
display: block;
}
2。)当鼠标悬停时,打开子菜单,
#leftcolumn ul.leftmenu #submenu a:hover {
color: #F9864D;
text-decoration:underline;
}
#leftcolumn ul.leftmenu #submenu {
display: none;
}
#leftcolumn ul.leftmenu li:hover #submenu {
display: block;
}
#leftcolumn ul.leftmenu #submenu a#activesubmenu {
color: #F9864D;
}
