如何使用JavaScript从段落提取引号内对话并存储到数组

嘿，这个需求其实挺常见的，尤其是处理文本内容的时候。我来给你分享两种靠谱的实现方式，核心都是用正则表达式来精准匹配引号里的内容：

方法一：用exec循环遍历匹配（兼容旧环境） #

这种方式适配所有JavaScript运行环境，包括一些版本较老的浏览器：

var myParagraph = ' “Of course I’ll go Kate. You should get back to bed. Would you like some Nyquil or Tylenol?” “Nyquil, please. Here are the questions and my mini-disc recorder. Just press record here. Make notes, I’ll transcribe it all.” “I know nothing about him,” I murmur, trying and failing to suppress my rising panic. “The questions will see you through. Go. It’s a...';

// 正则说明：匹配中文左引号“，捕获中间所有非右引号”的内容，直到遇到右引号
const quoteRegex = /“([^”]*)”/g;
const dialogues = [];

let matchResult;
// 循环执行exec，直到没有新的匹配结果
while ((matchResult = quoteRegex.exec(myParagraph)) !== null) {
  // matchResult[1]是捕获到的引号内内容，trim()去掉前后可能的冗余空格
  dialogues.push(matchResult[1].trim());
}

console.log(dialogues);

运行后会得到整理好的对话数组：

[
"Of course I’ll go Kate. You should get back to bed. Would you like some Nyquil or Tylenol?",
"Nyquil, please. Here are the questions and my mini-disc recorder. Just press record here. Make notes, I’ll transcribe it all.",
"I know nothing about him,"
]

方法二：用matchAll简化代码（ES6+） #

如果你的项目支持ES6及以上语法，用matchAll能让代码更简洁优雅：

var myParagraph = ' “Of course I’ll go Kate. You should get back to bed. Would you like some Nyquil or Tylenol?” “Nyquil, please. Here are the questions and my mini-disc recorder. Just press record here. Make notes, I’ll transcribe it all.” “I know nothing about him,” I murmur, trying and failing to suppress my rising panic. “The questions will see you through. Go. It’s a...';

const quoteRegex = /“([^”]*)”/g;
// 用matchAll获取所有匹配结果，转成数组后提取捕获组内容
const dialogues = Array.from(myParagraph.matchAll(quoteRegex)).map(item => item[1].trim());

console.log(dialogues);

额外适配：同时支持中英文引号 #

如果你的段落里混合了中文引号“”和英文引号""，可以把正则改成下面这样，同时匹配两种引号格式：

const quoteRegex = /["“]([^"”]*)["”]/g;

⚠️ 注意：如果文本里出现嵌套引号的极端情况（比如"He said: "Hello""），这个正则会失效，但日常对话类文本里几乎不会遇到这种场景，所以这个方案足够应付绝大多数需求。
