Do javascript function in browser widget?

[hh]

Most examples of that link assume that you have control of the pages.
And most use the js of the browser widget as "helper" only, the widget doesn't display
anything (is hidden).
Now you wrote that you don't have control.

So your "first experiments" method is one way to go, then you have full control.

My experiences are that there are no general rules how to do that. The best method
depends on the current content with all its variabilities. Andre gave some appropriate
and useful options.
You can also remove all css and js and set the htmltext of the widget to a string
with your own (inline) css and/or (inline) js, with or without any "do in widget".
** Merge() is the tool to use your templates. **
