JavaScript正则表达式（字符串应仅包含alpha，空格，连字符） [英] JavaScript Regex (string should include only alpha, space, hyphen)

问题描述

我正在尝试创建一个正则表达式，仅当字符串中包含除alpha，空格和连字符之外的任何内容时才会匹配。换句话说，字符串只能包含字母，空格和连字符。

I'm trying to create a regex that will match only when the string has anything but alphas, spaces, and hyphens. In other words, the string can only contain letters, spaces, and hyphens.

推荐答案

如果您正在寻找有效性测试：

If you are looking for a test for validity:

// from string start to end, only contains '-' "whitespace" or 'a'-'z' 
someString.match(/^[-\sa-zA-Z]+$/) 

或否定：

// has some invalid character not '-' "whitespace" or 'a'-'z'
someString.match(/[^-\sa-zA-Z]/)
