hi if you want to select element with id test2 you can use document.getElementById('test2') need to wrap test2 with quotes

and if element with id test2 is inside iframe you need to select iframe first and cal contentDocument

var iframe = document.getElementById('iframe-id');
iframe.contentDocument.getElementById('test2');

or if you are testing with chrome devtools you can change context and use document.getElementById('test2') as normal
