This example will be taking advantage of the [^] character group, this will match any character that is not in the group. This allows you to simply say any not-in-list character.

此示例将利用[^]字符组,这将匹配组中不存在的任何字符。这允许您简单地说出任何不在列表中的字符。

#([^[\., -\/#!$%\^&\*;:{}=\-_`~()]+)

var str = "#hello. foo bar";
var filter = RegExp = /#([^[\., -\/#!$%\^&\*;:{}=\-_`~()]+)/g;
var matches = Object = filter.exec(str);

if (matches !== null) {
    console.log("Found: " + matches[1]);
} else {
    console.log("nothing found");
}

#(.*?)[!.,?;:_-]

What you need is character class [].

你需要的是字符类[]。

[!.,?;:_-] match a single character present in the list below

[!。,?;:_-]匹配下面列表中的单个字符

     `!.,?;:_- a single character in the list !.,?;:_- literally`
