Javascript RegExp for splitting text into sentences and keeping the delimiter
提问by daktau
I am trying to use javascript's split to get the sentences out of a string but keep the delimiter eg !?.
我正在尝试使用 javascript 的拆分从字符串中获取句子，但保留分隔符，例如 !?。
So far I have
到目前为止我有
sentences = text.split(/[\.!?]/);
which works but does not include the ending punctuation for each sentence (.!?).
哪个有效，但不包括每个句子的结尾标点符号 (.!?)。
Does anyone know of a way to do this?
有谁知道这样做的方法？
回答by Larry Battle
You need to use match not split.
您需要使用匹配而不是拆分。
Try this.
尝试这个。
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);

The following is a small addition to Larry's answer which will match also paranthetical sentences:
以下是 Larry 的答案的一个小补充，它也将匹配附加句：
text.match(/\(?[^\.\?\!]+[\.!\?]\)?/g);
applied on:
应用于：
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!!!"
giveth:
给：
["If he's restin', I'll wake him up!", " (Shouts at the cage.)",
" 'Ello, Mister Polly Parrot!", " (Owner hits the cage.)", " There, he moved!!!"]

Try this instead:-
试试这个：-
sentences = text.split(/[\.!\?]/);
?is a special char in regular expressions so need to be escaped.
?是正则表达式中的特殊字符，因此需要进行转义。
Sorry I miss read your question - if you want to keep delimiters then you need to use matchnot splitsee this question
对不起，我想念你的问题 - 如果你想保留分隔符，那么你需要使用matchnot splitsee this question

A slight improvement on mircealungu's answer:
mircealungu 的回答略有改进：
string.match(/[^.?!]+[.!?]+[\])'"`'”]*/g);
- There's no need for the opening parenthesis at the beginning.
- Punctuation like
'...','!!!','!?'etc. are included inside sentences. - Any number of square close brackets and close parentheses are included. [Edit: different closing quotation marks added]
- 开头不需要左括号。
- 标点符号，如
'...'，'!!!'，'!?'等包括内部的句子。 - 包括任意数量的方括号和右括号。[编辑：添加了不同的右引号]
