javascript - 在 Javascript 中对 [Object Object] 数组进行排序

Question

我有一个结构如下的数组。

Object
    (
       [11065] => Object
              (
                  [firtname] => Linda
                  [lastname] => Bell
                  [fullname] => Bell, Linda

               )
       [11110] => Object
                (
                  [firstname] => Andrew
                  [lastname] => Smith
                  [fullname] => Andrew, Smith
                )
       [11279] => Object
               (
                  [firstname] => Sabrina
                  [lastname] => Wu
                  [fullname] => Sabrina Wu
               )

    )

如您所见，数组当前正在按 [11065]、[11110]、[11279] 给出的人员 ID 进行排序

有没有办法在 JavaScript 或 jQuery 中按人的姓氏对这个数组进行排序？

Use a compareFunction与 Array.sort(compareFunction)。为此，您需要包含的对象是一个数组，因此您可能想要执行如下操作:

var a = [{id: 11065,
          firstname: "Linda",
          lastname: "Bell"},
         {id: 11279,
          firstname: "Sabrina",
          lastname: "Wu"},
         {id: 11110,
          firstname: "Andrew",
          lastname: "Smith"}
];

a.sort(function (a, b) { if (a.lastname > b.lastname) {
                 return 1;
             } else if (a.lastname < b.lastname) {
                 return -1;
             } else {
                 return 0;
             }});

console.log(a);
