JS injection from Quickselection

[JoergAldinger]

Hello all,

I wonder if it is possible to inject some JavaScript from the Quickselection itself, rather than having to create a Java plugin that then does the @JSInject? It would be easier to deploy and update some easier functions this way. I am thinking of the "Extended JS" field in the Quickselection. Does it accept a little more complex code?

Think for example the Youtube video example, which basically injects some JS, one line of CSS and that's it...!?

Thanks and best regards,

Joerg.
