如何在非字母字符上分割字符串。 正则表达式JavaScript

Question

I have a sentence that I want to split into an array of words, but if there is punctuation included I end up with quotes in my array somehow.

 console.log("This is an example sentence! Dangit".split(/[\\W/]/)); // Outputs: ["This", "is", "an", "example", "sentence", "", "Dangit"] 

How do I fix this?

Answer 1

您可以改用match并寻找文字字符。

 console.log("This is an example sentence! Dangit".match(/\\w+/g)) 

Answer 2

Try [\\W]+ instead, which will combine multiple non-word chars together -

"This is an example sentence! Dangit".split(/[\W/]+/)

Array(6) [ "This", "is", "an", "example", "sentence", "Dangit" ]

Answer 3

单个和多个目标空间和标点符号：

[\s.?!,]+

 console.log("This is an example sentence! Dangit".split(/[\\s.?!,]+/));
