隱藏/顯示子菜單

Question

我想用jQuery隱藏/顯示子菜單。

所以最初'項目'只會是可見的。點擊後，會顯示子菜單。

我重視我目前的HTML代碼：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> 
 
<div class="menu-primary-menu-container"> 
 
    <ul id="menu-primary-menu" class="menu"> 
 
     <li id="menu-item-27" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-has-children menu-item-27"><a href="#">Projects</a> 
 
<ul> 
 
\t <li id="menu-item-26" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-26"><a href="/category/projects/residential/">Residential</a></li> 
 
\t <li id="menu-item-24" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-24"><a href="/category/projects/private/">Private</a></li> 
 
</ul> 
 
</li> 
 
    </ul> 
 
</div>

Answer 1

可以click()事件處理程序綁定到a

$('#menu-primary-menu>li>a').click(function() { 
 
    $(this).next().toggle(); 
 
    // if there is any other element after a the use 
 
    // $(this).parent().find('ul').toggle(); 
 
    // also if you need any better effect then use 
 
    // slideToggle() or fadeToggle instead of toggle() 
 
});

#menu-primary-menu>li>ul { 
 
    display: none 
 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> 
 
<div class="menu-primary-menu-container"> 
 
    <ul id="menu-primary-menu" class="menu"> 
 
    <li id="menu-item-27" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-has-children menu-item-27"><a href="#">Projects</a> 
 
     <ul> 
 
     <li id="menu-item-26" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-26"><a href="/category/projects/residential/">Residential</a> 
 
     </li> 
 
     <li id="menu-item-24" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-24"><a href="/category/projects/private/">Private</a> 
 
     </li> 
 
     </ul> 
 
    </li> 
 
    </ul> 
 
</div>
