我试图在导航栏上使用工具提示; 如果它在没有子菜单项的菜单项上实现，它会很有效，但如果我尝试在子菜单项上使用它，它就不会工作。
我的Navbar代码：
<!-- ============ START NAVBAR =========== -->
<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">

<!-- ============ END NAVBAR =========== -->
在此Navbar代码中，它将适用于＆＃34;有用的链接＆＃34; （这是一个主菜单项）
<li><a href="#links" data-toggle="tooltip" data-placement="top" title="Hooray!"><b>Useful links </b></a></li>
但如果我尝试在＃34; YWMP＆＃34;这是一个子菜单，它不会;
<li class="dropdown">
<a href="" class="dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><b>Programs </b><b class="caret"></b></a>
<ul class="dropdown-menu" id="menu3">
<li>
<a href="">Children and Youth <i class="fa fa-caret-right"></i></a>
<ul class="dropdown-menu sub-menu">
<li><a href="#mothers">Play Group</a></li>
<li><a href="#boys">Boys 2 Men</a></li>
<li><a href="#girls">Fun 4 Girls</a></li>
<li><a href="#teens">Drop In Cafe</a></li>
<li><a data-placement="bottom" data-toggle="tooltip" href="#youth" data-original-title="Youth Workshop Mentoring Program">YWMP</a></li>
<li><a href="#backyard">Backyard Sports</a></li>
</ul>
</li>
哦，这是我的jquery代码：
$(document).ready(function(){
$('[data-toggle="tooltip"]').tooltip();
});
答案 0 :(得分：1)
要显示工具提示，您需要具有title属性。替换
<a ... data-original-title="Youth Workshop Mentoring Program">YWMP</a>
带
<a ... title="Youth Workshop Mentoring Program">YWMP</a>
它会起作用。
