Question

好吧，我认为这个问题说明了一切，但为了清楚，我有以下表格（我知道它很长......我正在使用bootstrap ...和jquery）：

<form class="form-horizontal" role="form" ng-submit="cal.addEvent()"novalidate>

          <div class="form-group">
            <label class="control-label col-sm-2" for="title">Title:</label>
            <div class="col-sm-8"> 
              <input type="text" class="form-control" id="title" placeholder="Event Title" ng-model="cal.newEvent.title">
            </div>
          </div>
          <div class="form-group">
            <label class="control-label col-sm-2" for="desc">Description:</label>
            <div class="col-sm-8"> 
              <input type="text" class="form-control" id="desc" placeholder="Event Description" ng-model="cal.newEvent.description">
            </div>
          </div>
          <div class="form-group">
            <label class="control-label col-sm-2" for="stime">Start Time:</label>
            <div class="col-sm-8"> 
              <input type="time" class="form-control" id="stime" ng-model="cal.newEvent.start">
            </div>
          </div>
          <div class="form-group">
            <label class="control-label col-sm-2" for="etime">End Time:</label>
            <div class="col-sm-8"> 
              <input type="time" class="form-control" id="etime" ng-model="cal.newEvent.end">
            </div>
          </div>

          </div>
          <div class="form-group"> 
            <div class="col-sm-offset-2 col-sm-8">
              <button type="submit" class="btn btn-success btn-block"  data-role="none">Add Event</button>
            </div>
        </div>
    </form>

此表单位于指令中，如下所示：

app.directive("calendar", function($http) {
    return {
        restrict: "E",
        templateUrl: "templates/calendar.html",
        scope: true,
        transclude:true,
        link: function(scope)  {
            //there's a bunch of code here that I don't believe has anything to do with ng-submit so i left it out
        },
        controller: ["$scope", "$rootScope", function($scope, $rootScope){
            this.newEvent = {};

            this.removeEvent = function(index){
            $http.post("classes/main.php", {"fn": "calendarDel", "id": $scope.chosen[index].id}).success(function(data){
                $scope.getEvents($scope.chosen[index].date);
            });
            }

            this.addEvent = function(){
                //this.newEvent.date = $scope.dateString;
                console.log("AddEvent");
                console.log(this.newEvent);
            }
            $scope.getEvents = function(date){
                $http.post("classes/main.php", {"fn": "calendar", "id": $rootScope.user.id, "data": date}).success(function(data){
                    if(!data.Error){
                    $scope.chosen = data;
                    }
                });

            }
        }],
        controllerAs: 'cal'
    };
});

问题是，当我尝试提交表单时，我没有看到该函数被调用的迹象......我希望至少看到console.log("AddEvent");

有人在这里看到可能导致此问题的原因吗？

FYI

表单位于bootstrap 3模态div中，它位于调用它的同一个指令内---如果你需要看到“更大的图片”，可以这么说，只要问:)

我已尝试this.addEvent()，$scope.addEvent()，$rootScope.addEvent()无变更

Answer 1

您应该致电addEvent()

<form class="form-horizontal" role="form" ng-submit="addEvent()" novalidate>

并将函数绑定到范围，如

$scope.addEvent = function() {

来自expresssions

上的角度文档

表达式是根据范围对象
进行评估的

所以你不应该把表达式写成ng-submit="$scope.addEvent()"等

Answer 2

您应该向指令添加bindToController: true并指定scope: {}以创建隔离范围。

当使用隔离范围作为组件（参见上文）并使用controllerAs时，bindToController：true将允许组件将其属性绑定到控制器，而不是范围。实例化控制器时，隔离范围绑定的初始值已经可用。

参考：$compile

ng-submit不会在指令控制器
