Issues with AngularJS Validation not functioning properly with File Inputs marked as 'Required'

I've been experimenting with this issue and haven't been able to solve it. While creating an Angular form, I found that validation works fine when the required attribute is used in a text field. However, when I tried adding a file input type with the required attribute, I noticed that even after selecting a file, the $error.required message still showed up and the validation did not work properly. I have prepared a sample on jsfiddle for reference: http://jsfiddle.net/Alien_time/kxSaz/6/

Why is validation not working for file inputs? How can I make a required option validate correctly when using a file selection?

Answer №1

ngModelController currently does not have support for input type=file.

If you are facing this issue, one solution is to create a custom directive.

app.directive('validFile',function(){
  return {
    require:'ngModel',
    link:function(scope,el,attrs,ngModel){
      el.bind('change',function(){
        scope.$apply(function(){
          ngModel.$setViewValue(el.val());
          ngModel.$render();
        });
      });
    }
  }
});
