AngularJs-在UI-Bootstrap选项卡上添加自定义类

Question

如何在UI-Bootsrap的Tab导航上替换或添加新类。 我期待这样的事情，

<ul class="MY-CUSTOM-CLASS" ng-class="{'nav-stacked': vertical, 'nav-justified': justified}" ng-transclude="">
       <li ng-class="{active: active, disabled: disabled}" heading="Justified" class="ng-isolate-scope">
            <a href="" ng-click="select()" tab-heading-transclude="" class="ng-binding">Justified</a>
       </li>

       .....          
</ul> 

我已经尝试了以下方法，但是将类添加到了父类中，

<tabset justified="true" class="tab-nav">
       <tab heading="Justified">Justified content</tab>
       <tab heading="SJ">Short Labeled Justified content</tab>
       <tab heading="Long Justified">Long Labeled Justified content</tab>
</tabset>

好的，ui bootstrap模块不支持您不希望执行的操作，因此我们需要扩展模块以获取请求的行为。 为此，我们将使用装饰器：

.config(function($provide) {

  // This adds the decorator to the tabset directive 
  // @see https://github.com/angular-ui/bootstrap/blob/master/src/tabs/tabs.js#L88 
  $provide.decorator('tabsetDirective', function($delegate) {

    // The `$delegate` contains the configuration of the tabset directive as 
    // it is defined in the ui bootstrap module.
    var directive = $delegate[0];

    // This is the original link method from the directive definition
    var link = directive.link;

    // This sets a compile method to the directive configuration which will provide
    // the modified/extended link method
    directive.compile = function() {

      // Modified link method
      return function(scope, element, attrs) {

        // Call the original `link` method
        link(scope, element, attrs);

        // Get the value for the `custom-class` attribute and assign it to the scope.
        // This is the same the original link method does for the `vertical` and ``justified` attributes
        scope.customClass = attrs.customClass;
      }
    }

    // Return the modified directive
    return $delegate;
  });
});

这采用tabset指令的旧link方法，并用一个自定义方法包装它，该方法除了旧方法外还将custom-class属性的值绑定到作用域。 我们需要做的第二件事是覆盖模板以实际使用scope.customClass参数：

有多种方法可以使用$templateProvider或更简单的方法使用<scrip type="text/ng-template"> ：

  <script id="template/tabs/tabset.html" type="text/ng-template">
    <div>
      <ul class="{{customClass}} nav nav-{{type || 'tabs'}}" ng-class="{'nav-stacked': vertical, 'nav-justified': justified}" ng-transclude></ul>
      <div class="tab-content">
        <div class="tab-pane" ng-repeat="tab in tabs" ng-class="{active: tab.active}" tab-content-transclude="tab">
        </div>
      </div>
    </div>
  </script>
