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;
}
}

Answer 2

You cannot ajax a url from another domain unless it has implemented CORS

If you need to get data from somewhere which is not same origin you need to use JSONP

Also to debug, try calling the url from the locationbar to see if you receive valid data for your request
