我想创建一个内置指令项列表，并通过控制器共享

          <div class="controls">
               <a class="btn btn-danger" id="addBrunch" data-ng-click="addNew()">
                  <i class="icon-plus-sign"></i>

以下是我在plunker中的示例：

          <div class="controls">

      </div>

      <brunches-view class="well" data-ng-repeat="brunch in brunches">{{brunch}}</brunches-view>

      <br/>
      <p class="well">
          JSON: {{brunches | json}}
      </p>

      <div class="control-group">
          <div class="controls">

    $scope.$watch(function() { return $scope.brunches.length; }, function() {
        $scope.brunches = $scope.brunches.map(function (brunch) {
            return brunch;
        });
    });
});

app.directive('brunchesView', function ($compile) {
    return {
        restrict: 'E',
        templateUrl: 'brunch.html',
        controller: 'BrunchesCtrl',
        replace: true,
        link: function (scope, element, attrs, controller) {

app.directive('businessSubmit', function ($log, $compile, formManagerService) {

        controller: 'BrunchesCtrl',
        link: function (scope, element, attrs, controller) {
            formManagerService.init();
            var hasError;

            element.on('click', function (e) {
                e.preventDefault();
                $log.info("brunches: \n");

首先，

的

ng模型

设置为

地址

，但您要将其绑定到具有

地址

属性的

早午餐

对象。重要的是要认识到，

ng repeat

将为每个重复项创建一个子范围

          <div class="controls">
               <a class="btn btn-danger" id="addBrunch" data-ng-click="addNew()">
                  <i class="icon-plus-sign"></i>
                  add new...
              </a>
          </div>
      </div>

      <brunches-view class="well" data-ng-repeat="brunch in brunches">{{brunch}}</brunches-view>

      <br/>
      <p class="well">
          JSON: {{brunches | json}}
      </p>

      <div class="control-group">
          <div class="controls">
              <a class="btn btn-primary" href="#" data-business-submit>
                  <i class="icon-save"></i>
                  Save...
              </a>
          </div>
      </div>
  </div>
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>      
  <script src="//netdna.bootstrapcdn.com/bootstrap/3.0.3/js/bootstrap.min.js"></script>
  <script src="script.js"></script>

<input data-ng-model="brunch.address"/>

另一个问题是将父控制器也分配给指令。重要的是要了解控制器是单例的，所以如果您多次使用控制器，每个控制器都是一个单独的实例。因此，将父控制器嵌套在指令中是没有意义的

          <div class="controls">
               <a class="btn btn-danger" id="addBrunch" data-ng-click="addNew()">
                  <i class="icon-plus-sign"></i>
                  add new...
              </a>
          </div>
      </div>

      <brunches-view class="well" data-ng-repeat="brunch in brunches">{{brunch}}</brunches-view>

      <br/>
      <p class="well">
          JSON: {{brunches | json}}
      </p>

如果您希望与其他控制器共享数据，您应该设置一个服务，通过将数据注入需要访问的控制器中来保存

数据

是否有特殊原因让提交发生在指令中？一个简单的控制器函数怎么样，点击就调用它？我同意@mseemann。你想要达到的目标听起来很奇怪。你能举个例子吗？@iamstapper:

          <div class="controls">
               <a class="btn btn-danger" id="addBrunch" data-ng-click="addNew()">
                  <i class="icon-plus-sign"></i>
                  add new...
              </a>
          </div>
      </div>

      <brunches-view class="well" data-ng-repeat="brunch in brunches">{{brunch}}</brunches-view>

      <br/>
      <p class="well">
          JSON: {{brunches | json}}
      </p>

      <div class="control-group">
          <div class="controls">
              <a class="btn btn-primary" href="#" data-business-submit>
                  <i class="icon-save"></i>
                  Save...
              </a>
          </div>
      </div>
  </div>
