Javascript数组按姓氏,名字排序

Question

我在JavaScript中有以下数组,我需要按姓氏对它们进行排序.

var names = [Jenny Craig, John H Newman, Kelly Young, Bob];

结果将是:

Bob, 
Jenny Craig, 
John H Newman, 
Kelly Young 

有关如何执行此操作的任何示例？

Answer 1

试试这个:

function compare(a, b) {
    var splitA = a.split(" ");
    var splitB = b.split(" ");
    var lastA = splitA[splitA.length - 1];
    var lastB = splitB[splitB.length - 1];

    if (lastA < lastB) return -1;
    if (lastA > lastB) return 1;
    return 0;
}

var names = ["John H Newman", "Jenny Craig", "Kelly Young", "Bob"];
var sorted = names.sort(compare);
console.log(sorted);

这是一个小提琴.
