Answer 1

at least in android app, the js code in the js tab is included in head section of the html, meaning when it run, the document body is not parsed and no elements are accessible at this time...

you must run code accessing DOM after document load event by wrapping it in an onload event handler:

onload = function() {
// here DOM is accessible
};
