JavaScript function to return last word

In this article, I will show you how to return last word (string) using JavaScript.  The function will receive the textbox value and split using (.split) string functions in jQuery. Further, I have written code to return the last word.

JavaScript example:

<script type="text/javascript" src="//code.jquery.com/jquery-1.10.2.js"></script>

    <script type="text/javascript">

        $(document).ready(function () {

            $('#btnSubmit').click(function () {

                if ($.trim($('#txtName').val()) == '')

                    alert('input is blank'); else

                    var lastword = test($('#txtName').val());

                console.log(lastword);

                return false;

            });

            function test(words) {

                var n = words.split("");

                return n[n.length - 1];

            }

        });

    </script>

  <input type="text" id="txtName" placeholder="please entername" />

            <input id="btnSubmit" type="submit" value="Submit" />

Output:
