Node red ui builder with jquery?

[TomyT]

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
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
