Answer 1

req.onreadystatechange = function () { document.getElementById('divTxt').innerHTML = "My Status: " + req.responseText; }

you have to check, if the request was successful:

if (req.readyState === 4) { // what should be done with the result }

finally, it has to look like this:

req.onreadystatechange = function () {
if (req.readyState === 4) {
document.getElementById('divTxt').innerHTML = "My Status: " + req.responseText;
}
}
