javascript - 寻找一个正则表达式将字符串分成 2,3,4... 个单词

Question

假设我有这个字符串:

This is a test sentence. Actually, it is a paragraph really. Lets see how this goes

我想将其分成单个单词(包括标点符号)。例如，一次 2 个单词:

This is 
a test 
sentence. Actually, 
it is 
a paragraph 
really. Lets 
see how 
this goes

我可以使用以下方法获取单个单词:

/\w*(\D)\s*/g

那太好了，但是当我尝试使用这样的 3 个单词时:

/(\w*\D)\s(\w*\D)\s(\w*\D)/g

感觉不太对劲，看起来不太优雅。有些词也“悬而未决”。

Answer 1

使用\S+匹配一个或多个非空格字符。

> var s = 'This is a test sentence. Actually, it is a paragraph really. Lets see how this goes'
undefined
> s.match(/\S+\s+\S+/g)
[ 'This is',
  'a test',
  'sentence. Actually,',
  'it is',
  'a paragraph',
  'really. Lets',
  'see how',
  'this goes' ]
