Question

我想通过对话框弹出窗口将新行插入表中。此窗口具有表单和添加任务按钮以将新行插入表中。我尝试了所有的东西，但无法将此对话框的ng-model连接到表格。

Please see the demo:

Answer 1

在您的AddNewTask函数中传递了错误的对象：

 $scope.addNewTask=function(){
      $scope.tasks.push({$scope.task1, $scope.description1});
 }

应该是

$scope.addNewTask=function(){
     $scope.tasks.push({title : $scope.task1, description : $scope.description1});
 }

你错过了对象键。

Answer 2

您没有将有效地图添加到任务数组中。

由于您正在访问task.title和task.description，因此需要将它们作为map / JSON中的有效字段。最初这是格式化的JSON，其中：

{
    key: value,
    key: value,
    ...
}

因此，对于您尝试执行的数据：

       $scope.tasks.push({$scope.task1, $scope.description1});

但由于数据无法理解任务或描述的关键，所以您需要的是：

 $scope.addNewTask=function(){
       $scope.tasks.push({"title":$scope.task1, "description":$scope.description1});
    }

我不确定对方是否已经回答了这个问题。我在发布回复时被推迟了。
