我的列表顺序如下:
<ul>
<li>level 1 a
<ul>
<li>level 2 a
<ul>
<li>level 3 a</li>
<li>level 3 b</li>
</ul>
</li>
<li>level 2 b</li>
</ul>
</li>
<li>level 1 b
<ul>
<li>level 2 c
<ul>
<li>level 3 c</li>
<li>level 3 c</li>
</ul>
</li>
<li>level 2 d</li>
<li>level 2 e</li>
</ul>
</li>
</ul>
和jquery看起来像这样:
$(document).ready(function(){
$('li').click(function(ev) {
ev.stopPropagation();
$(this).children('ul').show();
$(this).prev().children('ul').hide();
$(this).siblings().children('ul li ul').hide();
$(this).next().children('ul').hide();
});
$('li > ul').hide();
});
当前情况:
1)我单击 1a级,然后单击 2a级,现在扩展了1a级和2a级
2)我单击 1b级,然后单击 1a级,我仍然看到1a级,并且其子级已展开。
>我想要的结果是:
当我单击1a级别时,它将折叠所有内容,而不是显示我之前单击的所有内容,如果我单击该1st级别,则将显示1b级别。
任何帮助都会很棒。谢谢

使用此方法单击children ul
sibling
时,您可以在li
上调用hide
$('li').click(function(ev) {
$(this).siblings('li').click(function() {
$(this).siblings('li').children('ul').hide()
})
$(document).ready(function() {
$('li').click(function(ev) {
$(this).siblings('li').click(function() {
$(this).siblings('li').children('ul').hide()
})
$(this).children('ul').children('li').children('ul').hide()
ev.stopPropagation();
$(this).parent('ul').show();
$(this).children('li').hide();
$(this).siblings('li').children('ul li ul').hide();
$(this).children('ul').show();
$(this).prev('li').children('ul li ul').hide();
$(this).next().children('ul').hide();
});
$('li > ul').hide();
});
current situation: 1) i click on level 1 a then level 2 a,
now level 1 a and level 2 a are expanded 2) i click on level 1 b,
then i click back the level 1 a,
i still see the level 1 a and its child is expanded. the outcome i want is: when i click back level 1 a,
it will collapse everything,
instead of showing everything that i clicked before,
same goes to level 1 b,
if i click that 1st.
