def increment_textbox_name(name):
    if not name.isdigit():
        return name
    num = int(name)
    num += 1
    return str(num)

function increment_textbox_name(name) {
    if (!name.match(/\d+/)) {
        return name;
    }
    var num = parseInt(name);
    num += 1;
    return num.toString();
}

var textbox = document.getElementById("textbox1");
textbox.name = increment_textbox_name(textbox.name);
