angularjs - 根据角度的路线变化添加或删除类

Question

我有 3 条包含 3 种形式的路线我试图根据 angular 中的当前路线在当前选项卡上设置引导活动类。我使用了 angular 路线模块。我怎样才能做到这一点。我附上js代码请检查并帮助

Answer 1

这可以使用 ng-class 来实现。只需在控制器中使用 $location 即可。这个例子很简单。这里我们在 $location.path() 等于 '/' 时向 div 添加一个活动类。

然后我们在视图中设置一个条件 ng-class 来添加活动类。

看法

<div ng-class="{active: location === '/'}">
  <p>The parent DIV will have active class added when location path equals '/'</p>
</div>

控制器

.controller('MainCtrl', function ($scope, $rootScope, $location) {
    $scope.location = $location.path();
    $rootScope.$on('$routeChangeSuccess', function() {
        $scope.location = $location.path();
    });
});

由于您使用 angular-ui-router 标记了您的问题，我假设您正在使用它。

使用 UI 路由器 ui-sref 结合 ui-sref-active 将允许您为当前活动状态（或任何子状态）分配一个类。

以这里为例。如果状态是 app.tab1（或子状态），则活动类将应用于 li 元素。

<ul>
  <li ui-sref-active='active'>
    <a ui-sref="app.tab1">link</a>
  </li>
  <li ui-sref-active='active'>
    <a ui-sref="app.tab2">link</a>
  </li>
  <li ui-sref-active='active'>
    <a ui-sref="app.tab3">link</a>
  </li>
</ul>

Answer 3

这适合像我这样的初学者：

HTML：

<script src="~/Content/src/angularjs/angular.min.js"></script>
<script src="~/Content/src/angularjs/angular-route.min.js"></script>

<ul>
  <li>
      <a ui-sref="Basics" href="#Basics" title="Basics" class="nav-link--link">Basics</a>
  </li>
</ul>

<div ng-app="myApp" ng-controller="MainCtrl">
  <div ng-view>

  </div>
</div>

角度：

//Create App
var app = angular.module("myApp", ["ngRoute"]);    

//Configure routes
app.config(function ($routeProvider) {
    $routeProvider
      .otherwise({ template: "<p>Coming soon</p>" })
      .when("/", {
        template: "<p>Coming soon</p>"
      })
      .when("/Basics", {
        templateUrl: "/content/views/Basic.html"
      });      
});    

//Controller 
app.controller('MainCtrl', function ($scope, $rootScope, $location) {
    $scope.location = $location.path();
    $rootScope.$on('$routeChangeSuccess', function () {
      navChanged();
    });
  });

  function navChanged() {
    setTimeout(function () {
      var links = angular.element(document.getElementsByClassName("nav-link--link"));
      var activeLink = null;
      for (var i = 0; i < links.length; i++) {
        var link = links[i]
        var linkElement = angular.element(link);
        linkElement.removeClass("active");
        var hash = location.hash.replace("#/", "#")
        if (link.hash && hash.split("#")[1] == link.hash.split("#")[1]) {
          activeLink = linkElement;
        }
      }
      activeLink.addClass("active");
    }, 100);
  };

Answer 4

您可以使用ng-class
