我刚刚写了一个指令。

用法:

<ul class="nav navbar-nav">
  <li active><a href="#/link1">Link 1</a></li>
  <li active><a href="#/link2">Link 2</a></li>
</ul>

实现:

angular.module('appName')
  .directive('active', function ($location, $timeout) {
    return {
      restrict: 'A',
      link: function (scope, element, attrs) {
        // Whenever the user navigates to a different page...
        scope.$on('$routeChangeSuccess', function () {
          // Defer for other directives to load first; this is important
          // so that in case other directives are used that this directive
          // depends on, such as ng-href, the href is evaluated before
          // it's checked here.
          $timeout(function () {
            // Find link inside li element
            var $link = element.children('a').first();

            // Get current location
            var currentPath = $location.path();

            // Get location the link is pointing to
            var linkPath = $link.attr('href').split('#').pop();

            // If they are the same, it means the user is currently
            // on the same page the link would point to, so it should
            // be marked as such
            if (currentPath === linkPath) {
              $(element).addClass('active');
            } else {
              // If they're not the same, a li element that is currently
              // marked as active needs to be "un-marked"
              element.removeClass('active');
            }
          });
        });
      }
    };
  });

测试:

'use strict';

describe('Directive: active', function () {

  // load the directive's module
  beforeEach(module('appName'));

  var element,
      scope,
      location,
      compile,
      rootScope,
      timeout;

  beforeEach(inject(function ($rootScope, $location, $compile, $timeout) {
    scope = $rootScope.$new();
    location = $location;
    compile = $compile;
    rootScope = $rootScope;
    timeout = $timeout;
  }));

  describe('with an active link', function () {
    beforeEach(function () {
      // Trigger location change
      location.path('/foo');
    });

    describe('href', function () {
      beforeEach(function () {
        // Create and compile element with directive; note that the link
        // is the same as the current location after the location change.
        element = angular.element('<li active><a href="#/foo">Foo</a></li>');
        element = compile(element)(scope);

        // Broadcast location change; the directive waits for this signal
        rootScope.$broadcast('$routeChangeSuccess');

        // Flush timeout so we don't have to write asynchronous tests.
        // The directive defers any action using a timeout so that other
        // directives it might depend on, such as ng-href, are evaluated
        // beforehand.
        timeout.flush();
      });

      it('adds the class "active" to the li', function () {
        expect(element.hasClass('active')).toBeTruthy();
      });
    });

    describe('ng-href', function () {
      beforeEach(function () {
        // Create and compile element with directive; note that the link
        // is the same as the current location after the location change;
        // however this time with an ng-href instead of an href.
        element = angular.element('<li active><a ng-href="#/foo">Foo</a></li>');
        element = compile(element)(scope);

        // Broadcast location change; the directive waits for this signal
        rootScope.$broadcast('$routeChangeSuccess');

        // Flush timeout so we don't have to write asynchronous tests.
        // The directive defers any action using a timeout so that other
        // directives it might depend on, such as ng-href, are evaluated
        // beforehand.
        timeout.flush();
      });

      it('also works with ng-href', function () {
        expect(element.hasClass('active')).toBeTruthy();
      });
    });
  });

  describe('with an inactive link', function () {
    beforeEach(function () {
      // Trigger location change
      location.path('/bar');

      // Create and compile element with directive; note that the link
      // is the NOT same as the current location after the location change.
      element = angular.element('<li active><a href="#/foo">Foo</a></li>');
      element = compile(element)(scope);

      // Broadcast location change; the directive waits for this signal
      rootScope.$broadcast('$routeChangeSuccess');

      // Flush timeout so we don't have to write asynchronous tests.
      // The directive defers any action using a timeout so that other
      // directives it might depend on, such as ng-href, are evaluated
      // beforehand.
      timeout.flush();
    });

    it('does not add the class "active" to the li', function () {
      expect(element.hasClass('active')).not.toBeTruthy();
    });
  });

  describe('with a formerly active link', function () {
    beforeEach(function () {
      // Trigger location change
      location.path('/bar');

      // Create and compile element with directive; note that the link
      // is the same as the current location after the location change.
      // Also not that the li element already has the class "active".
      // This is to make sure that a link that is active right now will
      // not be active anymore when the user navigates somewhere else.
      element = angular.element('<li class="active" active><a href="#/foo">Foo</a></li>');
      element = compile(element)(scope);

      // Broadcast location change; the directive waits for this signal
      rootScope.$broadcast('$routeChangeSuccess');

      // Flush timeout so we don't have to write asynchronous tests.
      // The directive defers any action using a timeout so that other
      // directives it might depend on, such as ng-href, are evaluated
      // beforehand.
      timeout.flush();
    });

    it('removes the "active" class from the li', function () {
      expect(element.hasClass('active')).not.toBeTruthy();
    });
  });
});

使用指令(因为我们在这里做的是DOM操作)，下面可能是最接近“angular方式”的方法:

$scope.timeFilters = [
  {'value':3600,'label':'1 hour'},
  {'value':10800,'label':'3 hours'},
  {'value':21600,'label':'6 hours'},
  {'value':43200,'label':'12 hours'},
  {'value':86400,'label':'24 hours'},
  {'value':604800,'label':'1 week'}
]

angular.module('whatever', []).directive('filter',function(){
return{
    restrict: 'A',
    template: '<li ng-repeat="time in timeFilters" class="filterItem"><a ng-click="changeTimeFilter(time)">{{time.label}}</a></li>',
    link: function linkFn(scope, lElement, attrs){

        var menuContext = attrs.filter;

        scope.changeTimeFilter = function(newTime){
          scope.selectedtimefilter = newTime;

        }

        lElement.bind('click', function(cevent){
            var currentSelection = angular.element(cevent.srcElement).parent();
            var previousSelection = scope[menuContext];

            if(previousSelection !== currentSelection){
                if(previousSelection){
                    angular.element(previousSelection).removeClass('active')
                }
                scope[menuContext] = currentSelection;

                scope.$apply(function(){
                    currentSelection.addClass('active');
                })
            }
        })
    }
}
})

然后你的HTML看起来像这样:

<ul class="dropdown-menu" filter="times"></ul>

我对这个问题的解决方案是使用路由。角模板中的电流。

当你在菜单中突出显示/tasks路由时，你可以将自己的属性menuItem添加到模块声明的路由中:

$routeProvider.
  when('/tasks', {
    menuItem: 'TASKS',
    templateUrl: 'my-templates/tasks.html',
    controller: 'TasksController'
  );

然后在模板任务中。你可以使用以下ng-class指令:

<a href="app.html#/tasks" 
    ng-class="{active : route.current.menuItem === 'TASKS'}">Tasks</a>

在我看来，这比所有提出的解决方案都要干净得多。

如果你想把指令的链接放在一个包装器中，而不是选择每个单独的链接(这样更容易查看Batarang中的作用域)，这也很有效:

  angular.module("app").directive("navigation", [
    "$location", function($location) {
      return {
        restrict: 'A',
        scope: {},
        link: function(scope, element) {
          var classSelected, navLinks;

          scope.location = $location;

          classSelected = 'selected';

          navLinks = element.find('a');

          scope.$watch('location.path()', function(newPath) {
            var el;
            el = navLinks.filter('[href="' + newPath + '"]');

            navLinks.not(el).closest('li').removeClass(classSelected);
            return el.closest('li').addClass(classSelected);
          });
        }
      };
    }
  ]);

加价就是:

    <nav role="navigation" data-navigation>
        <ul>
            <li><a href="/messages">Messages</a></li>
            <li><a href="/help">Help</a></li>
            <li><a href="/details">Details</a></li>
        </ul>
    </nav>

我还应该提到，我在这个例子中使用的是“全脂”jQuery，但你可以很容易地改变我所做的过滤等。

根据@kfis的回答，这是评论，我的建议，最终指令如下:

.directive('activeLink', ['$location', function (location) {
    return {
      restrict: 'A',
      link: function(scope, element, attrs, controller) {
        var clazz = attrs.activeLink;        
        var path = attrs.href||attrs.ngHref;
        path = path.substring(1); //hack because path does not return including hashbang
        scope.location = location;
        scope.$watch('window.location.href', function () {
          var newPath = (window.location.pathname + window.location.search).substr(1);
          if (path === newPath) {
            element.addClass(clazz);
          } else {
            element.removeClass(clazz);
          }
        });
      }
    };
  }]);

下面是它在html中的用法: < div ng-app = "链接" > <a href="#/one" active-link="active"> one </a> <a href="#/two" active-link="active">One</a> <a href="#" active-link="active">home</a> < / div > 之后用css样式: .活跃{颜色:红色;｝

$scope.getClass = function (path) {
return String(($location.absUrl().split('?')[0]).indexOf(path)) > -1 ? 'active' : ''
}


<li class="listing-head" ng-class="getClass('/v/bookings')"><a href="/v/bookings">MY BOOKING</a></li>
<li class="listing-head" ng-class="getClass('/v/fleets')"><a href="/v/fleets">MY FLEET</a></li>
<li class="listing-head" ng-class="getClass('/v/adddriver')"><a href="/v/adddriver">ADD DRIVER</a></li>
<li class="listing-head" ng-class="getClass('/v/bookings')"><a href="/v/invoice">INVOICE</a></li>
<li class="listing-head" ng-class="getClass('/v/profile')"><a href="/v/profile">MY PROFILE</a></li>
<li class="listing-head"><a href="/v/logout">LOG OUT</a></li>
