Hello,

I try to use jquery code inside my index.js file (using node red contrib uibuilder).  
But I always get an error if i use code like this: $('#container').hide();

The browser shows me: "Uncaught ReferenceError: $ is not defined".

I found an jquery example flow [jquery example](https://flows.nodered.org/flow/b76bb64411cca41646a20d243a71bc78/in/6c96b1c2350dcb4536903a3158d6254d)  
But there is now juqery code inside the index.js file.

Is there no way to use jquery or what am I doing wrong?

Thanks, Tom

Hello,

I found the problem 😉  
I forgot to implement the jquery script file inside the index.html.
