    Replace the lines

        if (!/(\.txt)$/i.test(obj.value)) {
    alert("Local file name must include the '.txt' extension.");
    return false;
}

    with

        if (!/(\.txt|\.htm|\.html)$/i.test(obj.value)) {
    alert("Local file name must include the '.txt', '.htm' or '.html' extension.");
    return false;
}

    For your convenience, it now takes htm-files as well.
