Adding a handler (or a constraint) in script is complicated.
The easiest way to do what you want is to subclass button, so you can write
your handler code in LZX:
<class name="mybutton" onclick="Debug.info("room url : %w")" />
then say:
... = new lz.mybutton(canvas, {text: roomName, xoffset: -20});
This is just the way LZX is. Some of the advanced features, that are simple in
LZX, actually turn into a lot of Javascript, that makes them not so simple in
script.
If you ever want to see what Javascript is generated by a certain LZX
construct, you can call `lzc -S` to see the intermediate Javascript before it
is compiled to the target platform. It's not pretty, but it can be helpful if
you _really_ have to do something in script, to see what you need to do.
