as $.get is similar as $.ajax, you might want to be looking into something I've done before.

I used to have the following code to return a value from an $.ajax request, but translated to your $.get.

function read (callback) {
    $.get("version.txt?_ts=" + new Date().getTime(), function (data) {
        var y1 = parseInt(data[0]);
        var y2 = parseInt(data[1]);
        var y = (y1 * 10) + y2;
        return callback(y);
    });
}

function readVersion () {
    read(function (result) { 
        console.log(result);
    });
}

Try this

function read() {
        var result=0;
            $.get("version.txt?_ts=" + new Date().getTime(), function (data) {
                var y1 = parseInt(data[0]);
                var y2 = parseInt(data[1]);
                var y = (y1 * 10) + y2;
                return y;
            });
        }

        function drr() {
            var d = read();
            document.write(d);
        }

To read local files you need to use the HTML5 File API. No matter how your JS/jQuery/AJAX looks like...

Check out the API here
