Uncaught ReferenceError: $ is not defined

Recommended Posts

Hi there, 

I was following this a tutorial about adding a page fade-in once the page has loaded. It is set up so it works even if javascript is disabled, which is ideal. https://www.abeautifulsite.net/a-clean-fade-in-effect-for-webpages

However i am trying to add another class the snippet to the script tag that appears immediately after the opening <body> tag: 

<script>document.body.className += ' fade-out'; $(".wrap").addClass(" fade-out");</script>

However I am getting the following error: "Uncaught ReferenceError: $ is not defined". I am assuming this is because I am not calling in jquery in the header? But why then does it work fine without my additional snippet?

Maybe I am taking the wrong approach here, let me know if this could work.

Thanks

You have vanilla JavaScript, and jQuery doing the same in adding a class. The plain JavaScript  will work fine, as it does not need a link to files etc to run, but jQuery does, hence the error
