问题描述

我想读的初始值ngModel。$ viewValue从不同的指令。

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
