Question

我正在尝试使用Angular的bootstrap.css。我引用了Twitter Bootstrap Navbar with AngularJS - Collapse Not Functioning但是当我尝试实现此代码时，我的导航栏不会崩溃，下拉列表也不起作用。

代码：

<nav id="navbar-example" class="navbar navbar-inverse navbar-static" role="navigation" ng-controller="NavBarCtrl">
  <div class="container-fluid">
    <div class="navbar-header">
      <button class="navbar-toggle" type="button" ng-click="isCollapsed = !isCollapsed">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Title</a>
    </div>
    <div collapse="isCollapsed" class="navbar-collapse bs-js-navbar-collapse">
      <ul class="nav navbar-nav">
      <li><a href="">home</a></li>
        <li class="dropdown">
          <a id="drop1" href="#" role="button" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
          <ul class="dropdown-menu" role="menu" aria-labelledby="drop1">
            <li role="presentation"><a role="menuitem" tabindex="-1" href="http://twitter.com/fat">Action</a></li>
            <li role="presentation"><a role="menuitem" tabindex="-1" href="http://twitter.com/fat">Separated link</a></li>
          </ul>
        </li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <li id="fat-menu" class="dropdown">
          <a href="#" id="drop3" role="button" class="dropdown-toggle" data-toggle="dropdown">Dropdown 3 <b class="caret"></b></a>
          <ul class="dropdown-menu" role="menu" aria-labelledby="drop3">
            <li role="presentation"><a role="menuitem" tabindex="-1" href="http://twitter.com/fat">Action</a></li>
          </ul>
        </li>
      </ul>
    </div><!-- /.nav-collapse -->
  </div><!-- /.container-fluid -->
</nav>

var myApp = angular.module('myApp', ['ui.bootstrap']);

function NavBarCtrl($scope) {
    $scope.isCollapsed = true;
}

为什么不崩溃？这是JSFiddle。

Answer 1

您是否已检入开发人员工具？它正在显示

https://fiddle.jshell.net/code.angularjs.org/1.2.9/angular.js Failed to load resource: the server responded with a status of 404 (Not Found)

ui-bootstrap-tpls.js:7 Uncaught ReferenceError: angular is not defined

因为角度无法加载，因此角度自举也无法初始化。

所以请尝试添加另一个角度cdn并进行测试。

Answer 2

我认为您需要在此部分添加类show

 <div ng-class="collapse navbar-collapse" [ngClass]="{'show':!isCollapsed}">

Navbar没有与Angular崩溃
