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 aa 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 .
