如何在 Ember.js 和 Rails 中使用甜蜜警报

Question

我是一名 Ember 菜鸟，在使用 ember/rails 应用程序时遇到了一些问题。我相信我有一个范围问题，我不太确定如何处理..

在我的控制器内部，我有一个删除操作，其中包含以下代码：

swal({
  title: "Are you sure?"
  text: "You will not be able to recover this post!"
  type: "warning"
  showCancelButton: true
  confirmButtonColor: "#DD6B55"
  confirmButtonText: "Yes, delete it!"
  closeOnConfirm: false
}, ->
  @get('model').destroyRecord().then =>
    @transitionToRoute 'posts'
  swal("Deleted!", "Your post has been deleted.", "success")

)

我将错误追溯到'@get('model').destroyRecord().then'，我很确定这是因为我在控制器操作内部的函数内部调用'this.get' .但是，我不知道如何解决这个问题......如何在函数中引用控制器？有关如何纠正此问题或实现相同功能的更好方法的任何建议？

我不知道 coffescript，但也许您可以尝试将控制器分配给变量？

controller = this; // or @ ? 
swal({
  title: "Are you sure?"
  text: "You will not be able to recover this post!"
  type: "warning"
  showCancelButton: true
  confirmButtonColor: "#DD6B55"
  confirmButtonText: "Yes, delete it!"
  closeOnConfirm: false
}, ->
  controller.get('model').destroyRecord().then =>
    controller.transitionToRoute 'posts'
  swal("Deleted!", "Your post has been deleted.", "success")
)

使用行为：在数据中：

<%= link_to "Delete", s, :method => :delete, data: { behavior: 'delete' } %>

$("[data-behavior='delete']").on("click", function(e){
    e.preventDefault();

    swal({
        title: "Are you sure you want to delete " , 
        text: "You will not be able to recover this data!", 
        type: "warning", 
        showCancelButton: true, 
        confirmButtonColor: "#DD6B55", 
        confirmButtonText: "Yes, delete it!", 
        closeOnConfirm: false 
    }, function(isConfirm) { 
        if (isConfirm)  
        { 
           // here you can use ajax to delete 
           swal("Deleted!", "Ok , rooms will be delete after submit.", "success"); 
        } 
        else  
        { 
           return false;            
        } 
    }); 
});
