Add/Remove Input Fields Dynamically In AngularJS

Hi:

I have to add remove input fields dynamically in angularJS. I am including a working Javascript implementation below:

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript" src="https://www.sanwebe.com/wp-content/cache/minify/e907d.js"></script>
<script>
$(document).ready(function() {
    var max_fields      = 10; //maximum input boxes allowed
    var wrapper         = $(".input_fields_wrap"); //Fields wrapper
    var add_button      = $(".add_field_button"); //Add button ID

    var x = 1; //initlal text box count
    $(add_button).click(function(e){ //on add input button click
        e.preventDefault();
        if(x < max_fields){ //max input box allowed
            x++; //text box increment
            $(wrapper).append('<div><input type="text" name="mytext[]"/><a href="#" class="remove_field">Remove</a></div>'); //add input box
        }
    });

    $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
        e.preventDefault(); $(this).parent('div').remove(); x--;
    });
});
</script>
<div class="input_fields_wrap">
    <button class="add_field_button">Add More Fields</button>
    <div><input type="text" name="mytext[]"></div>
</div>

</body>
</html>

I need the same things in angularJS to start with. This implementation is Javascript and uses a Javascript library. This is essentially https://www.sanwebe.com/2013/03/addremove-input-fields-dynamically-with-jquery
this example.

A working example of same thing in angularJS would be great.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

           var container =   angular.element(document.getElementById('container'));
           var childNode = $compile(htmlStr)(container);
           container.append(childNode);

           });
        }
    };
 
   });
app.directive("removeMe", function($rootScope) {
      return {
            link:function(scope,element,attrs)
            {
                element.bind("click",function() {
                    element.remove();
                });
            }
      }

});
app.controller('myCtrl', function($scope){

put jQuery plugin before angularjs plugin so angularjs know jquery is in the place. you should considere not using jQuery and only AngularJS with its jQuery lite integrated
also, end of line 35 </div> instead </div\>
