AngularJS:从不同指令读取 ngModel.$viewValue 的初始值 [英] AngularJS: read initial value of ngModel.$viewValue from different directive

问题描述

我想从不同的指令中读取初始值 ngModel.$viewValue.

I would like to read the initial value ngModel.$viewValue from different directive.

# 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)

我非常感谢您的帮助.

推荐答案

我只是自己修复了...愚蠢:)

I just fixed it myself... stupid :)

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

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

确实有效！哎呀！
