AngularJS:从不同指令读取 ngModel.$viewValue 的初始值

Question

我想从不同的指令读取初始值 ngModel.$viewValue。

# coffee script
app.directive 'directive', -> 
  return {
      require: '?ngModel',
      link: (scope, element, attrs, ngModelCtrl) ->
      ........
           console.log(ngModelCtrl.$viewValue) # does give NaN!

           ngModelCtrl.$setViewValue('something'); # only after setting reading does work
           console.log(ngModelCtrl.$viewValue)

我真的很感谢任何帮助。

我自己修好了......愚蠢:)

    link: (scope, element, attrs, ngModelCtrl) ->

        scope.$watch(ngModelCtrl, ->
          console.log(ngModelCtrl.$viewValue)
        )

确实有效!耶皮!
