在JavaScript中对混合的字母/数字数组进行排序
问题描述：
var x = ['1','2A','2B','2AA','2','10A','10','11','12A','12B','12']
所需的输出
sortedArray = ['1','2','2A','2B','2AA','10','10A','11','12','12A','12B']
我曾经尝试过使用lodash，但没有得到想要的结果
var x = ['1','2A','2B','2AA','2','10A','10','11','12A','12B','12']
_.sortBy(x);
//lodash result
["1", "10", "10A", "11", "12", "12A", "12B", "2", "2A", "2AA", "2B"]
答
您可以使用 localeCompare
You can use parseInt to get the number part and sort it. If both a and b have the same number, then sort them based their length. If they both have the same length, then sort them alphabetically using localeCompare
let array = ['1','2A','2B','2AA','2','10A','10','11','12A','12B','12'];
array.sort((a, b) => parseInt(a) - parseInt(b)
|| a.length - b.length
|| a.localeCompare(b));
console.log(array)
