Angular is automatically adding 'ng-invalid' class on 'required' fields

Question

I am building an angular app for which I have some forms set up. I have some fields that are required to be filled before submission. Therefore I have added \'required\' on

Answer 1

Try to add the class for validation dynamically, when the form has been submitted or the field is invalid. Use the form name and add the 'name' attribute to the input. Example with Bootstrap:

    Username*
    

        
    

It is also important, that your form has the ng-submit="" attribute:

 
 ....

  Submit

You can also add an optional function for validation to the form:

//within your controller (some extras...)

$scope.checkSubmit = function () {

   if ($scope.myForm.$valid) {
        alert('All good...'); //next step!

   }
   else {
        alert('Not all fields valid! Do something...');
    }

 }

Now, when you load your app the class 'has-error' will only be added when the form is submitted or the field has been touched. Instead of:
!myForm.username.$pristine

You could also use:
myForm.username.$dirty
