Hi. Add code example or workspace to your Q. It's hard to know like this what is the problem/error.

In general, if you want to use Jquery you need first to include Jquery library. The code below will throw this error:

Uncaught ReferenceError: $ is not defined

<script>    
        $( "p" );   
    </script>

    <script
    src="http://code.jquery.com/jquery-3.2.1.min.js"
    integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4="
    crossorigin="anonymous">
    </script>
