Answer 1

Although HTML id is allowed to contain dot and colon characters, the fact that you are using jQuery makes it doesn't work because dot and colon have special meaning in a a selector context.

The following native JS will work:

document.getElementById('tb_10.3.3.186:32222').innerHTML += html;

But if you still want to use jQuery, you need to remove the dot (.) and colon (:) from your id.
