使用Ajax回调进行角度形式重置 [英] Angular Form Resetting with Ajax Callbacks

问题描述

我有一个基本表单，在提交时运行了一个角度 $ save 操作：

I have a basic form with an Angular $save action run on submit:

app.controller 'MyThingCtrl', ($scope, MyThing) ->
    this.addThing = ->
      new MyThing(this.thing).$save(
        (data) ->
          console.log 'New Thing Saved'
          $scope.things.push data
          this.thing = {}
        ,(err) ->
          console.log 'Error: ' + err
        )

期望的是 this.thing 的表单将在成功时重置，但不是，因为此不再引用以前的操作。

The expectation is that the form for this.thing will be reset on success, but it isn't, as the this no longer refers to what it did before.

推荐答案

虽然范围 c的范围在回调中已更改，但变量事物可通过 $ scope 由Angular提供：

While the scope of this is changed inside the callback, the variable thing is available via the $scope variable provided by Angular:

app.controller 'MyThingCtrl', ($scope, MyThing) ->
    this.addThing = ->
      new MyThing(this.thing).$save(
        (data) ->
          console.log 'New Thing Saved'
          $scope.things.push data
          $scope.thing = {}
        ,(err) ->
          console.log 'Error: ' + err
        )
