问题描述

我有一个字段，您可以在其中输入您的姓名并提交.我希望接收人的名字和姓氏，为此，我需要检查值是否至少包含2个字.这是我现在正在使用的东西，但似乎不起作用.

I have a field that you enter your name in and submit it. I would like the receive peoples first and last names and to do this i need to check if the value contains at least 2 words. This is what I am using right now but it doesn't seem to work.

    var NAME = name.value;
    var matches = NAME.match(/\b[^\d\s]+\b/g);
    if (matches && matches.length >= 2) {
        //two or more words
        return true;
    } else {
        //not enough words
        return false;
    }
}
