How do return a javascript function return an HTML?

I took the following function in JavaScript (jQuery):

      function CustomAlert() {
            this.show = function (nome) {


            };

        }
        var Alert = new CustomAlert();

        $(document).ready(function () {
            Alert.show('meu nome e hugo');
        });

How do I get it back, write the following HTML screen:

<div class="nome">meu nome e hugo</div>
