I need to replace all non alpha-numeric characters in a file name except for the period, I've been searching around and found close answers but not exact, here is what I narrowed it down to:
我需要用一个文件名替换所有非字母数字的字符，除了这段时间，我一直在搜索，找到了接近的答案，但不准确，这里是我把它缩小到:
var temp = originalname.replace(/\W+/g, "_");
But this replaces everything, how can I exclude the period here (or any other characters if possible)?
但这取代了一切，我怎么能排除这里的周期(或任何其他字符，如果可能)?

You can use a negated character class:
你可以使用一个否定字符类:
var temp = originalname.replace(/[^\w.]+/g, "_");
[^\w.]+ will match 1 or more of any character that is not a word character and not a DOT.
[^ \ w。+将匹配1个或多个不是单词字符的字符，而不是一个点。
