Javascript正则表达式用于将文本拆分为句子并保留分隔符

Question

我正在尝试使用JavaScript的分割来获取字符串中的句子，但保留分隔符例如！？。

到目前为止，我有

sentences = text.split(/[\\.!?]/); 

其作品，但不包括对每个句子结束标点符号（！？）。

有谁知道一种方法来做到这一点？

Answer 1

您需要使用匹配不分裂。

试试这个。

var str = "I like turtles. Do you? Awesome! hahaha. lol!!! What's going on????"; 
var result = str.match(/[^\.!\?]+[\.!\?]+/g); 

var expect = ["I like turtles.", " Do you?", " Awesome!", " hahaha.", " lol!!!", " What's going on????"]; 
console.log(result.join(" ") === expect.join(" ")) 
console.log(result.length === 6); 

Answer 2

试试这个： -

sentences = text.split(/[\\.!\?]/); 

?是在正则表达式特殊字符所以需要进行转义。

对不起，我错过读您的问题 - 如果你想保留分隔符，那么你需要使用match没有split看到this question

Answer 3

下面是一个小除了拉里的回答也将匹配paranthetical句子：适用于

text.match(/\(?[^\.\?\!]+[\.!\?]\)?/g); 

：

text = "If he's restin', I'll wake him up! (Shouts at the cage.) 
'Ello, Mister Polly Parrot! (Owner hits the cage.) There, he moved!!!" 

所赐：

["If he's restin', I'll wake him up!", " (Shouts at the cage.)", 
" 'Ello, Mister Polly Parrot!", " (Owner hits the cage.)", " There, he moved!!!"]
