通过点击p元素来显示/隐藏li

Question

我希望可以通过点击p来显示/隐藏ul。我的HTML看起来像这样： -

<li class="type_unknown depth_2"> 
    <p class="tree_item branch"> 
     <a href="http://moodlelive.dev/mod/wiki/view.php?pageid=1123"> 
      <span class="glyphicon glyphicon-spacer"></span> &nbsp;Daoust University Refreshs 
     </a> 
    </p> 
    <ul id="yui_3_15_0_4_1495615549528_188"> 
     <li class="type_unknown depth_3"> 
     <p class="tree_item leaf"> 
      <a href="http://moodlelive.dev/mod/wiki/view.php?pageid=1257"><span class="glyphicon glyphicon-spacer"></span> &nbsp;REFRESH DIVERSITEIT</a> 
     </p> 
     </li> 
     <li class="type_unknown depth_3"> 
     <p class="tree_item leaf"> 
      <a href="http://moodlelive.dev/mod/wiki/view.php?pageid=1230"><span class="glyphicon glyphicon-spacer"></span> &nbsp;REFRESH DOELGROEPENVERMINDERINGEN</a> 
     </p> 
     </li> 
     <li class="type_unknown depth_3" id="yui_3_15_0_4_1495615549528_187"> 
     <p class="tree_item leaf wiki_newentry" id="yui_3_15_0_4_1495615549528_186"> 
      <a href="http://moodlelive.dev/mod/wiki/view.php?pageid=1167"><span class="glyphicon glyphicon-spacer"></span> &nbsp;REFRESH FEESTDAGEN</a> 
     </p> 
     </li> 
     <li class="type_unknown depth_3"> 
     <p class="tree_item leaf"> 
      <a href="http://moodlelive.dev/mod/wiki/view.php?pageid=1270"><span class="glyphicon glyphicon-spacer"></span> &nbsp;REFRESH VREEMDELINGEN</a> 
     </p> 
     </li> 
    </ul> 
</li> 

你可以看到我在李一个p标签也是一个UL标签。布局是这样的：

但我想有可能把它打开或关闭。

打开：

休息日：

所以，当你点击它，内容打开或关闭。我怎样才能做到这一点？

Answer 1

你可以像下面： -

$('.tree_item').click(function(e){ 
    e.stopPropagation(); 
    $(this).next('ul').toggle(); 
}); 

例如： -

$('.tree_item').click(function(e){ 
 
    e.stopPropagation(); 
 
    $(this).next('ul').toggle(); 
 
});

ul,li{ 
 
list-style:none; 
 
}
