Question

我有一长串地址，每个地址的结构类似于：

123 Main Street St. Louisville OH 43071,432

我想在状态，邮政编码，门牌号上分割地址字符串（在上述情况下，这将是：OH 43071,432）。虽然我有一个正则表达式组合来标识每个字符串（/ \ d +，\ d + /）中的这些元素，但基于此的拆分会导致分隔符被删除。

虽然我看到了其他堆栈溢出线程来解决与此类似的问题，但这些解决方案均无效。例如，如果我将正则表达式组合放在一个捕获组中，例如（/（\ d +，\ d +）/），它将在另一行返回邮政编码和地址：

[ '123 Main Street St. Louisville OH ',
  '43071,432',

类似地，添加？！或regex组合中的？=无效。

如何成功拆分地址字符串，所以输出将镜像：

[ '123 Main Street St. Louisville OH 43071,432',
   Main Long Road St. Louisville OH 43071,786

我的地址列表是：

let addr =
  "123 Main Street St. Louisville OH 43071,432 Main Long Road St. Louisville OH 43071,786 High Street Pollocksville NY 56432,54 Holy Grail Street Niagara Town ZP 32908,3200 Main Rd.

Answer 1

由于匹配项重叠，您将无法使用split-而是对捕获组重复使用.exec，然后提取捕获组。匹配逗号或字符串开头，然后先行查找，捕获地址字符串，后跟逗号和数字：

const addr = "123 Main Street St. Louisville OH 43071,432 Main Long Road St. Louisville OH 43071,786 High Street Pollocksville NY 56432,54 Holy Grail Street Niagara Town ZP 32908,3200 Main Rd. Bern AE 56210,1 Gordon St. Atlanta RE 13000,10 Pussy Cat Rd. Chicago EX 34342,10 Gordon St. Atlanta RE 13000,58 Gordon Road Atlanta RE 13000,22 Tokyo Av. Tedmondville SW 43098,674 Paris bd. Abbeville AA 45521,10 Surta Alley Goodtown GG 30654,45 Holy Grail Al. Niagara Town ZP 32908,320 Main Al. Bern AE 56210,14 Gordon Park Atlanta RE 13000,100 Pussy Cat Rd. Chicago EX 34342,2 Gordon St. Atlanta RE 13000,5 Gordon Road Atlanta RE 13000,2200 Tokyo Av. Tedmondville SW 43098,67 Paris St. Abbeville AA 45521,11 Surta Avenue Goodtown GG 30654,45 Holy Grail Al. Niagara Town ZP 32918,320 Main Al. Bern AE 56215,14 Gordon Park Atlanta RE 13200,100 Pussy Cat Rd. Chicago EX 34345,2 Gordon St. Atlanta RE 13222,5 Gordon Road Atlanta RE 13001,2200";
let match;
const matches = [];
const pattern = /(?:^|,)(?=([^,]+,\d+))./g
while (match = pattern.exec(addr)) {
  matches.push(match[1]);
}
console.log(matches);

如果仅在具有最新Node.js版本的后端上需要此操作，则可以将split()与后置断言一起使用。此代码也可以在最新的Google Chrome浏览器版本中进行测试。

const addr = "123 Main Street St. Louisville OH 43071,432 Main Long Road St. Louisville OH 43071,786 High Street Pollocksville NY 56432,54 Holy Grail Street Niagara Town ZP 32908,3200 Main Rd. Bern AE 56210,1 Gordon St. Atlanta RE 13000,10 Pussy Cat Rd. Chicago EX 34342,10 Gordon St. Atlanta RE 13000,58 Gordon Road Atlanta RE 13000,22 Tokyo Av. Tedmondville SW 43098,674 Paris bd. Abbeville AA 45521,10 Surta Alley Goodtown GG 30654,45 Holy Grail Al. Niagara Town ZP 32908,320 Main Al. Bern AE 56210,14 Gordon Park Atlanta RE 13000,100 Pussy Cat Rd.

console.log(addr.split(/(?<=\d+,\d+) /));

要在更新的问题上匹配字符串，可以使用RegExp /[^\s][^,]+,\d+/g和String.prototype.match()来匹配不是空格字符" "的字符，然后是一个或多个字符不是逗号字符,，后跟逗号字符和一个或多个数字字符

let addr = "123 Main Street St. Louisville OH 43071,432 Main Long Road St. Louisville OH 43071,786 High Street Pollocksville NY 56432,54 Holy Grail Street Niagara Town ZP 32908,3200 Main Rd.

let res = addr.match(/[^\s][^,]+,\d+/g);

console.log(JSON.stringify(res, null, 2));
