Javascript 如何在正则表达式匹配之前提取行？

我试图在

地址正则表达式匹配之前提取
店铺名称
和
地址
。我被困了一段时间。谢谢最终我也想得到电话，但我不知道如何得到。有人能帮我吗

功能：

function getShopInfo(text) {

const addrRegex = /[0-9]+.+(Singapore\s+\d{6}|S\d{6})/g;
const titleRegex = `/(.*\n){1}${addrRegex}/`; // extract the title before the address
if (text.match(titleRegex)) {
    const title = text.match(titleRegex);
    console.log(title);
    console.log(addr);
    console.log("\n")
  } else {
    console.log('Message: No TITLE before ADDRESS found!');
  }

}

仅使用一种模式：在第一个捕获组中捕获标题（其行中的所有内容），在下一行中，在行的开头捕获一个数字，最后在
新加坡
之后，使用

(.+)\n(\d+.*Singapore \d{6}\b)

到目前为止，我将对测试用例使用以下正则表达式
（.*）\n（\d+.*Singapore\s+\d{6}）
，它假设地址只有一行，并且标题（或非地址行）显示在地址之前。如果你想要更好的东西，你应该包括更多的测试用例，感谢@CertainPerformance的快速响应。我可以知道while循环中的[名称，地址]是什么吗？我没有得到第一个逗号，这是解构。它从匹配数组中获取
[1]
和
[2]
标记，并将它们放入两个变量名
title
和
address
（同时丢弃
[0]
索引-这就是为什么在第一个逗号之前没有任何标记）您将其说得非常清楚。我接受这个答案。谢谢@CertainPerformance
