以上的指导性建议对我都没用。如果你有一个这样的引导导航栏

<ul class="nav navbar-nav">
    <li><a ng-href="#/">Home</a></li>
    <li><a ng-href="#/about">About</a></li>
  ...
</ul>

(可以是$ yo的angular启动)然后你要将.active添加到父元素<li>类列表中，而不是元素本身;即<li class="active">..</li>. .所以我写了这个:

.directive('setParentActive', ['$location', function($location) {
  return {
    restrict: 'A',
    link: function(scope, element, attrs, controller) {
      var classActive = attrs.setParentActive || 'active',
          path = attrs.ngHref.replace('#', '');
      scope.location = $location;
      scope.$watch('location.path()', function(newPath) {
        if (path == newPath) {
          element.parent().addClass(classActive);
        } else {
          element.parent().removeClass(classActive);
        }
      })
    }
  }
}])

使用set-parent-active;.active是默认值，所以不需要设置

<li><a ng-href="#/about" set-parent-active>About</a></li>

当链接激活时，父元素<li>将是.active。要使用另一个.active类，如.highlight，只需

<li><a ng-href="#/about" set-parent-active="highlight">About</a></li>

Here is the solution that I came up with after reading some of the excellent suggestions above. In my particular situation, I was trying to use Bootstrap tabs component as my menu, but didn't want to use the Angular-UI version of this because I want the tabs to act as a menu, where each tab is bookmark-able, rather than the tabs acting as navigation for a single page. (See http://angular-ui.github.io/bootstrap/#/tabs if you're interested in what the Angular-UI version of bootstrap tabs looks like).

I really liked kfis's answer about creating your own directive to handle this, however it seemed cumbersome to have a directive that needed to be placed on every single link. So I've created my own Angular directive which is placed instead once on the ul. Just in case any one else is trying to do the same thing, I thought I'd post it here, though as I said, many of the above solutions work as well. This is a slightly more complex solution as far as the javascript goes, but it creates a reusable component with minimal markup.

下面是指令的javascript和ng:view的路由提供程序:

var app = angular.module('plunker', ['ui.bootstrap']).
  config(['$routeProvider', function($routeProvider) {
    $routeProvider.
        when('/One', {templateUrl: 'one.html'}).
        when('/Two', {templateUrl: 'two.html'}).
        when('/Three', {templateUrl: 'three.html'}).
        otherwise({redirectTo: '/One'});
  }]).
  directive('navTabs', ['$location', function(location) {
    return {
        restrict: 'A',
        link: function(scope, element) {
            var $ul = $(element);
            $ul.addClass("nav nav-tabs");

            var $tabs = $ul.children();
            var tabMap = {};
            $tabs.each(function() {
              var $li = $(this);
              //Substring 1 to remove the # at the beginning (because location.path() below does not return the #)
              tabMap[$li.find('a').attr('href').substring(1)] = $li;
            });

            scope.location = location;
            scope.$watch('location.path()', function(newPath) {
                $tabs.removeClass("active");
                tabMap[newPath].addClass("active");
            });
        }

    };

 }]);

然后在你的html中你只需:

<ul nav-tabs>
  <li><a href="#/One">One</a></li>
  <li><a href="#/Two">Two</a></li>
  <li><a href="#/Three">Three</a></li>
</ul>
<ng:view><!-- Content will appear here --></ng:view>

这里是它的活塞:http://plnkr.co/edit/xwGtGqrT7kWoCKnGDHYN?p=preview。

我是这样做的:

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

myApp.directive('trackActive', function($location) {
    function link(scope, element, attrs){
        scope.$watch(function() {
            return $location.path();
        }, function(){
            var links = element.find('a');
            links.removeClass('active');
            angular.forEach(links, function(value){
                var a = angular.element(value);
                if (a.attr('href') == '#' + $location.path() ){
                    a.addClass('active');
                }
            });
        });
    }
    return {link: link};
});

这可以让你在一个有跟踪活动指令的节中有链接:

<nav track-active>
     <a href="#/">Page 1</a>
     <a href="#/page2">Page 2</a>
     <a href="#/page3">Page 3</a>
</nav>

在我看来，这种方法比其他方法干净得多。

此外，如果你使用的是jQuery，你可以让它更整洁，因为jQlite只有基本的选择器支持。在angular include之前包含jquery的一个更简洁的版本是这样的:

myApp.directive('trackActive', function($location) {
    function link(scope, element, attrs){
        scope.$watch(function() {
            return $location.path();
        }, function(){
            element.find('a').removeClass('active').find('[href="#'+$location.path()+'"]').addClass('active');
        });
    }
    return {link: link};
});

这是一个jsFiddle

在我的例子中，我通过创建一个负责导航的简单控制器来解决这个问题

angular.module('DemoApp')
  .controller('NavigationCtrl', ['$scope', '$location', function ($scope, $location) {
    $scope.isCurrentPath = function (path) {
      return $location.path() == path;
    };
  }]);

只需像这样在元素中添加ng-class:

<ul class="nav" ng-controller="NavigationCtrl">
  <li ng-class="{ active: isCurrentPath('/') }"><a href="#/">Home</a></li>
  <li ng-class="{ active: isCurrentPath('/about') }"><a href="#/about">About</a></li>
  <li ng-class="{ active: isCurrentPath('/contact') }"><a href="#/contact">Contact</a></li>
</ul>

在视图

<a ng-class="getClass('/tasks')" href="/tasks">Tasks</a>

在控制器

$scope.getClass = function (path) {
  return ($location.path().substr(0, path.length) === path) ? 'active' : '';
}

这样，tasks链接将在任何以'/tasks'开头的url中具有活动类。/任务/ 1 /报告)

也有同样的问题。以下是我的解决方案:

.directive('whenActive',
  [
    '$location',
    ($location)->
      scope: true,
      link: (scope, element, attr)->
        scope.$on '$routeChangeSuccess', 
          () ->
            loc = "#"+$location.path()
            href = element.attr('href')
            state = href.indexOf(loc)
            substate = -1

            if href.length > 3
              substate = loc.indexOf(href)
            if loc.length is 2
              state = -1

            #console.log "Is Loc: "+loc+" in Href: "+href+" = "+state+" and Substate = "+substate

            if state isnt -1 or substate isnt -1
              element.addClass 'selected'
              element.parent().addClass 'current-menu-item'
            else if href is '#' and loc is '#/'
              element.addClass 'selected'
              element.parent().addClass 'current-menu-item'
            else
              element.removeClass 'selected'
              element.parent().removeClass 'current-menu-item'
  ])
