使用javascript删除除字母数字和空格以外的所有字符 [英] Remove all characters except alphanumeric and spaces with javascript

问题描述

我喜欢所提供的解决方案从字符串中删除不是字母数字字符。遇到[\]字符时出现问题但是如何在保留空格的情况下执行此操作？

I like the solution povided by "Remove not alphanumeric characters from string. Having trouble with the [\] character" but how would I do this while leaving the spaces in place?

我需要根据清空后的空格来标记字符串。

I need to tokenize string based on the spaces after it has been cleaned.

推荐答案

input.replace(/[^\w\s]/gi, '')

从另一个答案中无耻地偷走了。字符类中的 ^ 表示不是。所以这是不是 \w （相当于 \W ）而不是 \s ，这是空格字符（空格，制表符等）。如果需要，您可以使用文字 。

Shamelessly stolen from the other answer. ^ in the character class means "not." So this is "not" \w (equivalent to \W) and not \s, which is space characters (spaces, tabs, etc.) You can just use the literal if you need.
