"An error occurred while attempting to use the trim function on an AngularJS

Can someone explain why the native JavaScript trim() function does not seem to be compatible with AngularJS?

<input ng-model="myInput">

if($scope.myInput.trim() != ''){
alert('required');
return false;
}

Answer №1

Although the trim() function is perfectly fine, when checking for an empty string, it's important to ensure that

   $scope.login = function () {       
    if($scope.myInput.trim() == ''){
     alert('required');
      }
    };
