javascript - 对对象的javascript数组进行排序

Question

我有一个如下所示的数组:

data = 
[
    {name: "Monday", amount: 67, colour: "red"},

    {name: "Tuesday", amount: 23, colour: "blue"},

    {name: "Wednesday", amount: 50, colour: "yellow"},

    {name: "Thursday", amount: 70, colour: "green"},

    {name: "Friday", amount: 20, colour: "orange"},

    {name: "Saturday", amount: 90, colour: "black"},

    {name: "Sunday", amount: 10, colour: "brown"}
]

我想按“金额”值降序对数组进行排序，因此排序后，数组将如下所示:

data = 
[
    {name: "Saturday", amount: 90, colour: "black"},

    {name: "Thursday", amount: 70, colour: "green"},

    {name: "Monday", amount: 67, colour: "red"},

    {name: "Wednesday", amount: 50, colour: "yellow"},

    {name: "Tuesday", amount: 23, colour: "blue"},

    {name: "Friday", amount: 20, colour: "orange"},

    {name: "Sunday", amount: 10, colour: "brown"}
]

我在 stackoverflow 上看到过各种与此类似的帖子，但我发现很难将这些问题解释为像我这样的问题，它具有命名索引(名称、数量、颜色)，而不仅仅是 [0]、[ 1], [2] 等

Answer 1

使用Array.sort :

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