Jquery 导航栏子菜单上的引导工具提示不工作

我试图在导航栏上使用工具提示； 如果它在一个没有子菜单项的菜单项上实现，效果会很好，但是如果我尝试在一个子菜单项上使用它，它将不起作用

我的导航条码：

为了显示工具提示，您需要具有

title

属性。替换

<a ... data-original-title="Youth Workshop Mentoring Program">YWMP</a>

YWMP

与

YWMP

---

它会起作用的。

谢谢。。。解决了我的问题。新手错误-在切换到W3Schools示例中的“有用链接”菜单项之前，我将此JSFIDLE用作YWMP菜单项的原始示例。（我猜jsfiddle使用了一些定制的css&jquery，但没有包括在内）

<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>

$(document).ready(function(){
    $('[data-toggle="tooltip"]').tooltip();
});
