jQuery 从字符串中删除特殊字符等 [英] jQuery remove special characters from string and more

问题描述

我有一个这样的字符串:

I have a string like this:

var str = "I'm a very^ we!rd* Str!ng.";

我想要做的是从上面的字符串中删除所有特殊字符并替换空格，如果它们被键入，下划线，带有 - 字符.

What I would like to do is removing all special characters from the above string and replace spaces and in case they are being typed, underscores, with a - character.

上面的字符串在转换"之后看起来像这样:

The above string would look like this after the "transformation":

var str = 'im-a-very-werd-strng';

推荐答案

replace(/[^a-z0-9s]/gi, '') 会将字符串过滤为仅字母数字值和 replace(/[_s]/g, '-') 将用连字符替换下划线和空格:

replace(/[^a-z0-9s]/gi, '') will filter the string down to just alphanumeric values and replace(/[_s]/g, '-') will replace underscores and spaces with hyphens:

str.replace(/[^a-z0-9s]/gi, '').replace(/[_s]/g, '-')

Regex 来源:Javascript 的 RegEx 仅允许字母数字
