Question

说我有这个字符串：

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

我想在个别单词（包括标点符号）上进行分块。例如，一次2个单词：

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

我可以使用以下方式获得单词：

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

太好了，但是当我用这样的东西尝试3个单词时：

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

感觉不对，看起来并不优雅。有些话留下了＆＃34;悬空＆＃34;太

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' ]

Answer 2

你可以用它。而不是“3”，你想要的每行数字为1，如例子中所示（3给出4个单词）。

var s = 'This is a test sentence. Actually, it is a paragraph really. Lets see how this goes'
undefined
s.match(/(\S+)(\s+\S+){0,3}/g)
Array [ "This is a test", "sentence. Actually, it is", "a paragraph really. Lets", "see how this goes" ]

寻找一个正则表达式将一个字符串组成2,3,4 ...单词
