怎么做反向拆分

Question

这里我有两个变量（值），在这两个我想要的值中：

1. countryName
2. stateName
3. cityName
4. localityName
5. sublocalityName

所以我使用的是split()，但它工作不正常，第一个字符串工作正常，但第二个字符串无法正常工作，我认为反过来我们已拆分字符串，我们必须记录所有这些值，但我不知道该怎么做？

＆＃13;
＆＃13;
var address = "8th Main Rd, Marathahalli Village, Marathahalli, Bengaluru, Karnataka 560037, India";

var resAddress = address.split(",");
var sublocalityNameTrim = resAddress[1];
var sublocalityName = sublocalityNameTrim.trim();
var localityNameTrim = resAddress[2];
var localityName = localityNameTrim.trim();
var cityNameTrim = resAddress[3];
var cityName = cityNameTrim.trim();
var stateAndPincode = resAddress[4];
var countryTrim = resAddress[5];
var countryName = countryTrim.trim();
var sc = stateAndPincode.trim();
var stateAndPincodeSplid = sc.split(" ");
var stateNameTrim = stateAndPincodeSplid[0];
var stateName = stateNameTrim.trim();
var pincode = stateAndPincodeSplid[1];

console.log("countryName = " + countryName);
console.log("stateName = " + stateName);
console.log("cityName = " + cityName);
console.log("localityName = " + localityName);
console.log("sublocalityName = " + sublocalityName);


var address1 = "846, 2nd Main Rd, AECS Layout - D Block, AECS Layout, Marathahalli, Bengaluru, Karnataka 560037, India";

var resAddress1 = address1.split(",");
var sublocalityNameTrim = resAddress1[1];
var sublocalityName = sublocalityNameTrim.trim();
var localityNameTrim = resAddress1[2];
var localityName = localityNameTrim.trim();
var cityNameTrim = resAddress1[3];
var cityName = cityNameTrim.trim();
var stateAndPincode = resAddress1[4];
var countryTrim = resAddress1[5];
var countryName = countryTrim.trim();
var sc = stateAndPincode.trim();
var stateAndPincodeSplid = sc.split(" ");
var stateNameTrim = stateAndPincodeSplid[0];
var stateName = stateNameTrim.trim();
var pincode = stateAndPincodeSplid[1];

console.log("countryName = " + countryName);
console.log("stateName = " + stateName);
console.log("cityName = " + cityName);
console.log("localityName = " + localityName);
console.log("sublocalityName = " + sublocalityName);

Answer 1

请在下面找到有效的解决方案。我使用了Object而不是单个变量。您可以根据需要提取属性并分配给变量。

var address1 = "8th Main Rd, Marathahalli Village, Marathahalli, Bengaluru, Karnataka 560037, India";

var address2 = "846, 2nd Main Rd, AECS Layout - D Block, AECS Layout, Marathahalli, Bengaluru, Karnataka 560037, India"

function getAddObj(add) {
  var addArray = add.split(',').reverse().map(function(item) {
    return item.trim()
  })
  return addArray.reduce(function(acc, item, index) {
    switch (index) {
      case 0:
        acc.country = item;
        return acc;
      case 1:
        acc.state = item.split(' ')[0]
        return acc;
      case 2:
        acc.city = item;
        return acc;
      case 3:
        acc.locality = item;
        return acc;
      case 4:
        acc.subLocality = item;
        return acc;
      default:
        return acc;
    }
  }, {});
}

var countryName = getAddObj(address1).country;
var stateName = getAddObj(address1).state;

console.log(countryName);
console.log(stateName);

Answer 3

var address1 = "8th Main Rd, Marathahalli Village, Marathahalli, Bengaluru, Karnataka 560037, India";
var address2 = "846, 2nd Main Rd, AECS Layout - D Block, AECS Layout, Marathahalli, Bengaluru, Karnataka 560037, India"

function printObj(add) {
    var resAddress = add.split(',').reverse()
    console.log("countryName = " + resAddress[0].trim());
    console.log("stateName = " + resAddress[1].trim());
    console.log("cityName = " + resAddress[2].trim());
    console.log("localityName = " + resAddress[3].trim());
    console.log("sublocalityName = " + findSubLocality(resAddress));
}

function findSubLocality(data) {
    var subLocality = "";
    for (var i = data.length - 1; i >= 4; i--) {
        subLocality = subLocality + data[i] + ",";
    }
    subLocality = subLocality.substr(0, subLocality.length - 1);
    return subLocality;
}

printObj(address1);
printObj(address2);
