我使用Twitter bootstrap"下拉"不是"下拉"带有html标记的多级菜单。
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
<li><a tabindex="-1" href="#">Action</a></li>
<li><a tabindex="-1" href="#">Another action</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
<li><a tabindex="-1" href="#">Action</a></li>
<li><a tabindex="-1" href="#">Another action</a></li>
<li><a tabindex="-1" href="#">Something else here</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
<li><a tabindex="-1" href="#">Action</a></li>
<li><a tabindex="-1" href="#">Another action</a></li>
</ul>
</li>
<li class="divider"></li>
<li><a tabindex="-1" href="#">Separated link</a></li>
</ul>
</li>
<li><a tabindex="-1" href="#">Something else here</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
<li><a tabindex="-1" href="#">Action</a></li>
<li><a tabindex="-1" href="#">Another action</a></li>
<li><a tabindex="-1" href="#">Something else here</a></li>
<li class="divider"></li>
<li><a tabindex="-1" href="#">Separated link</a></li>
</ul>
</li>
<li class="divider"></li>
<li><a tabindex="-1" href="#">Separated link</a></li>
</ul>
我有一个问题。我可以添加点击事件来显示子菜单吗?
答案 0 :(得分:5)
子菜单由css显示。因此,首先禁用css(悬停)并在菜单项中添加单击事件。
html示例:
<div class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Show menu</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
<li><a tabindex="-1" href="#">Action</a></li>
<li><a tabindex="-1" href="#">Another action</a></li>
<li class="dropdown-submenu">
<a tabindex="-1" href="#">More options</a>
<ul class="dropdown-menu">
<li><a tabindex="-1" href="#">Action</a></li>
<li><a tabindex="-1" href="#">Another action</a></li>
</ul>
</li>
<li class="divider"></li>
<li><a tabindex="-1" href="#">Separated link</a></li>
</ul>
</div>
禁用css :
.dropdown-submenu:hover > .dropdown-menu {
display: none;
}
通过javascript触发点击:
$('.dropdown-submenu').click(function(){
$('.dropdown-submenu > .dropdown-menu').css('display','block');
return false;
});
注意当你有一个子菜单时,每个子菜单都有自己的类
