如果你不愿意使用AngularStrap，那么这个指令可以帮到你!这是对https://stackoverflow.com/a/16231859/910764的修改。

JavaScript

angular.module('myApp').directive('bsNavbar', ['$location', function ($location) {
  return {
    restrict: 'A',
    link: function postLink(scope, element) {
      scope.$watch(function () {
        return $location.path();
      }, function (path) {
        angular.forEach(element.children(), (function (li) {
          var $li = angular.element(li),
            regex = new RegExp('^' + $li.attr('data-match-route') + '$', 'i'),
            isActive = regex.test(path);
          $li.toggleClass('active', isActive);
        }));
      });
    }
  };
}]);

HTML

<ul class="nav navbar-nav" bs-navbar>
  <li data-match-route="/home"><a href="#/home">Home</a></li>
  <li data-match-route="/about"><a href="#/about">About</a></li>
</ul>

注意:上面的HTML类假设您正在使用Bootstrap 3.x

JavaScript

/**
 * Main AngularJS Web Application
 */

var app = angular.module('yourWebApp', [
    'ngRoute'
]);


/**
 * Setup Main Menu
 */

app.controller('MainNavCtrl', [ '$scope', '$location', function ( $scope, $location) {
    $scope.menuItems = [
        {
            name: 'Home',
            url:  '/home',
            title: 'Welcome to our Website'
        },
        {
            name: 'ABOUT',
            url:  '/about',
            title: 'Know about our work culture'
        },
        {
            name:   'CONTACT',
            url:    '/contact',
            title:  'Get in touch with us'
        }
    ];

    $scope.isActive = function (viewLocation) {
        return viewLocation === $location.path();
    };
}]);

HTML

  <div class="navbar-collapse collapse" ng-controller="MainNavCtrl">
    <ul id="add-magic-line" class="nav navbar-nav navbar-right">
      <li data-ng-class="{current_page_item: isActive('{{ menuItem.url }}')}" data-ng-repeat="menuItem in menuItems">
        <a data-ng-href="#{{menuItem.url}}" title="{{menuItem.title}}">
          {{menuItem.name}}
        </a>
      </li>
    </ul>
  </div>

一个非常优雅的方法是使用ng-controller在ng-view之外运行一个单独的控制器:

<div class="collapse navbar-collapse" ng-controller="HeaderController">
    <ul class="nav navbar-nav">
        <li ng-class="{ active: isActive('/')}"><a href="/">Home</a></li>
        <li ng-class="{ active: isActive('/dogs')}"><a href="/dogs">Dogs</a></li>
        <li ng-class="{ active: isActive('/cats')}"><a href="/cats">Cats</a></li>
    </ul>
</div>
<div ng-view></div>

并包含在controllers.js中:

function HeaderController($scope, $location) 
{ 
    $scope.isActive = function (viewLocation) { 
        return viewLocation === $location.path();
    };
}

这是一个简单的解决方案

<ul class="nav navbar-nav navbar-right navbar-default menu">
  <li ng-class="menuIndice == 1 ? 'active':''">
    <a ng-click="menuIndice = 1" href="#/item1">item1</a>
  </li>
  <li ng-class="menuIndice == 2 ? 'active':''">
    <a ng-click="menuIndice = 2" href="#/item2">item2</a>
  </li>
  <li ng-class="menuIndice == 3 ? 'active':''">
    <a ng-click="menuIndice = 3" href="#/item3">item3</a>
  </li>
</ul>

我使用ng-class指令和$location来实现它。

<ul class="nav">
<li data-ng-class="{active: ($location.path() == '/') }">
    <a href="#/">Carpeta Amarilla</a>
</li>
<li class="dropdown" data-ng-class="{active: ($location.path() == '/auditoria' || $location.path() == '/auditoria/todos') }">
    <a class="dropdown-toggle" data-toggle="dropdown" href="#">
        Auditoria
        <b class="caret"></b>
    </a>
    <ul class="dropdown-menu pull-right">
        <li data-ng-class="{active: ($location.path() == '/auditoria') }">
            <a href="#/auditoria">Por Legajo</a>
        </li>
        <li data-ng-class="{active: ($location.path() == '/auditoria/todos') }">
            <a href="#/auditoria/todos">General</a>
        </li>
    </ul>
</li>
</ul>

它要求导航条在一个主控制器中，可以像这样访问$location服务:

bajasApp.controller('MenuCntl', ['$scope','$route', '$routeParams', '$location', 
   function MenuCntl($scope, $route, $routeParams, $location) {
   $scope.$route = $route;
   $scope.$location = $location;
   $scope.$routeParams = $routeParams;
}]);

感谢@Pylinux。我使用了他的技术，并对其进行了修改，以支持“一级”下拉菜单(sub ul/li)，因为这是我所需要的。在下面的小提琴链接中看到它的实际操作。

根据pylinux的答案- http://jsfiddle.net/abhatia/en4qxw6g/更新了Fiddle

为了支持一级下拉菜单，我做了以下三个修改: 1. 为li下的“a”元素添加了一个类值dd(下拉)，该元素需要有子ul列表。

         <li><a class="dd">This link points to #/fun5</a>
          <ul>
            <li><a href="#/fun6?some=data">This link points to #/fun6</a>
            </li>
            <li><a href="#/fun7?some=data">This link points to #/fun7</a>
            </li>
            <li><a href="#/fun8?some=data">This link points to #/fun8</a>
            </li>
            <li><a href="#/fun9?some=data">This link points to #/fun9</a>
            </li>
          </ul>
        </li>

2. 更新Javascript以添加以下新逻辑。

 if(angular.element(li).parent().parent().children('a').hasClass("dd"))
 {angular.element(li).parent().parent().children('a.dd').addClass('active');}

3.更新后的CSS添加如下内容:

a.active {background-color:red;}

希望这将有助于有人寻求实现单级下拉菜单。
