In jquery what is uncaught reference error $ is not defined

Question

please tell me how to fix it

Answer 1

The error means "quot; symbol was not defined.
if you did not load the jquery script this error happens.
Include the below script inside the head tag of your html. it will load properly
<script src="https://code.jquery.com/jquery-3.2.1.min.js">

Answer 2

Your javascript code loads before your script. that's why "quot; is undefined.
Wrap your entire Javascript code like below
it will work correctly
window.onload = function(){
// your entire js code
}
