javascript - JavaScript 中的数组 sort() 给出了错误的答案

Question

当我尝试使用 sort() 进行排序时，数组中有间隔，然后它给了我错误的答案并且无法对其进行排序..有人知道如何对此进行排序吗？ 这是我尝试过的

array=["1050-3000","150-250","1-49","3001-9999","251-400","401-600","601-1049","50-149"]

当我排序时:- array.sort(); 它给了我这个答案:-

["1-49","1050-3000","150-250","3001-9999","251-400","401-600","601-1049","50-149"]

但我期望的是:-

["1-49","50-149","150-250","251-400","401-600","601-1049","1050-3000","3001-9999"]

Answer 1

您必须拆分字符串并比较第一个元素。

let array = ["1050-3000", "150-250", "1-49", "3001-9999", "251-400", "401-600", "601-1049", "50-149"];

array.sort((a, b) => a.split("-")[0] - b.split("-")[0]);

console.log(array);
