Uncaught ReferenceError: myFunction is not defined at HTMLInputElement.onkeyup-CodePudding

Basically the same thing as https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_ev_onkeyup

But I am getting this error for some reason.

HTML

<nb-card>
  <nb-card-header>
    Enter your name: 
  </nb-card-header>
  <nb-card-body>
    <input type="text" id="fname" onkeyup="myFunction()">
  </nb-card-body>
  <script>
    function myFunction() {
      var x = document.getElementById("fname");
      x.value = x.value.toUpperCase();
    }
    </script>
</nb-card>

Error Nb Card

Same error without the nebular library: HTML

<html>
<body>
  Enter your name: 
  <input type="text" id="fname" onkeyup="myFunction()">

  <script>
    function myFunction() {
      var x = document.getElementById("fname");
      x.value = x.value.toUpperCase();
    }
  </script>
</body>
</html>

Does anyone know why? Thanks.

I have tried many other stack overflow solutions and they do not work. I am hoping to not use JQuery. This should have worked but it doesn't. I follow the other W3 School examples and get the same error.

your code seems to work fine here. What's the problem?

<nb-card>
  <nb-card-header>
    Enter your name: 
  </nb-card-header>
  <nb-card-body>
    <input type="text" id="fname" onkeyup="myFunction()">
  </nb-card-body>
  <script>
    function myFunction() {
      var x = document.getElementById("fname");
      x.value = x.value.toUpperCase();
    }
    </script>
</nb-card>

This isn't how to code in AngularJS. Make use of the platform's baked-in functionality - like using ng-click, ng-model and ng-keyup

In this case, I think the solution is as easy as using a CSS class to force the uppercase, but still, I hope this helps.

angular.module('myApp', [])
  .controller('myCtrl', ['$scope', '$http', function($scope, $http) {
    $scope.fname = "";
    $scope.myFunction = function() {
      console.log($scope.fname)
    }
  }]);

.ucase {
  text-transform: uppercase;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
  <nb-card>
    <nb-card-header>
      Enter your name:
    </nb-card-header>
    <nb-card-body>
      <input type="text" ng-model="fname" class='ucase' ng-keyup="myFunction()">
    </nb-card-body>
  </nb-card>
</div>
