As I said, it is much easier to do the whole logic in Smalltalk and
just regenerate the whole part without the element ...
Anyway, it is possible in JavaScript with something like that:
"if the element #foo is there, remove it "
(html selector new add: '#foo'; size)
then: (html element id: 'foo'; remove)
This generates something like:
$$('#foo').size() ? $('foo').remove()
