对混合的字母/数字数组排序

Question

我有一个混合数组,我需要按字母顺序排序,然后按数字排序

[A1, A10, A11, A12, A2, A3, A4, B10, B2, F1, F12, F3]

我如何将其排序为:

[A1, A2, A3, A4, A10, A11, A12, B2, B10, F1, F3, F12]

我试过了

arr.sort(function(a,b) {return a - b});

但是只按字母顺序对其进行排序.可以使用直接JavaScript或jQuery完成吗？

Answer 1

var reA = /[^a-zA-Z]/g;
var reN = /[^0-9]/g;

function sortAlphaNum(a, b) {
  var aA = a.replace(reA, "");
  var bA = b.replace(reA, "");
  if (aA === bA) {
    var aN = parseInt(a.replace(reN, ""), 10);
    var bN = parseInt(b.replace(reN, ""), 10);
    return aN === bN ? 0 : aN > bN ? 1 : -1;
  } else {
    return aA > bA ? 1 : -1;
  }
}
console.log(
["A1", "A10", "A11", "A12", "A2", "A3", "A4", "B10", "B2", "F1", "F12", "F3"].sort(sortAlphaNum)
)

Answer 2

const sortAlphaNum = (a, b) => a.localeCompare(b, 'en', { numeric: true })`

用法:

const sortAlphaNum = (a, b) => a.localeCompare(b, 'en', { numeric: true })
console.log(['A1', 'A10', 'A11', 'A12', 'A2', 'A3', 'A4', 'B10', 'B2', 'F1', 'F12', 'F3'].sort(sortAlphaNum))

得到:

["A1", "A2", "A3", "A4", "A10", "A11", "A12", "B2", "B10", "F1", "F3", "F12"]

您可能必须将'en'参数更改为您的语言环境或以编程方式确定,但这适用于英语字符串.

也localeCompare没有超一贯支持,但如果与你的通天塔那transpiling将不会是一个问题

Answer 3

我有类似的情况,但是,有一个字母数字和数字混合,需要先排序所有数字后跟字母数字,所以:

A10
1
5
A9
2
B3
A2

需要成为:

1
2
5
A2
A9
A10
B3

我能够使用提供的算法并在其上进行更多操作来实现此目的:

var reA = /[^a-zA-Z]/g;
var reN = /[^0-9]/g;
function sortAlphaNum(a,b) {
    var AInt = parseInt(a, 10);
    var BInt = parseInt(b, 10);

    if(isNaN(AInt) && isNaN(BInt)){
        var aA = a.replace(reA, "");
        var bA = b.replace(reA, "");
        if(aA === bA) {
            var aN = parseInt(a.replace(reN, ""), 10);
            var bN = parseInt(b.replace(reN, ""), 10);
            return aN === bN ? 0 : aN > bN ? 1 : -1;
        } else {
            return aA > bA ? 1 : -1;
        }
    }else if(isNaN(AInt)){//A is not an Int
        return 1;//to make alphanumeric sort first return -1 here
    }else if(isNaN(BInt)){//B is not an Int
        return -1;//to make alphanumeric sort first return 1 here
    }else{
        return AInt > BInt ? 1 : -1;
    }
}
var newlist = ["A1", 1, "A10", "A11", "A12", 5, 3, 10, 2, "A2", "A3", "A4", "B10", "B2", "F1", "F12", "F3"].sort(sortAlphaNum);

Answer 4

您可以使用 Intl.Collator

与Read here 相比，它具有性能优势localeCompare

浏览器可比性（所有浏览器都支持）

let arr = ["A1", "A10", "A11", "A12", "A2", "A3", "A4", "B10", "B2", "F1", "F12", "F3"]

let op = arr.sort(new Intl.Collator('en',{numeric:true, sensitivity:'accent'}).compare)

console.log(op)

Answer 5

一种简单的方法是使用https://www.w3schools.com/jsref/jsref_localecompare.asp的localeCompare（）方法JavaScript

例：

export const sortAlphaNumeric = (a, b) => {
    // convert to strings and force lowercase
    a = typeof a === 'string' ? a.toLowerCase() : a.toString();
    b = typeof b === 'string' ? b.toLowerCase() : b.toString();

    return a.localeCompare(b);
};
