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:
