javascript - 多维数组排序

Question

我在 javascript 中有一个多维数组定义为:-

myArray[0][0] = Some IMage;
myArray[0][1] = Some price;
myArray[0][2] = Some name;
myArray[0][3] = Some values;
myArray[0][4] = Some otherValues;
myArray[1][0] = Some IMage;
myArray[1][1] = Some price;
myArray[1][2] = Some name;
myArray[1][3] = Some values;
myArray[1][4] = Some otherValues;

现在我的工作是根据价格对它们进行排序。如何做到这一点？

Answer 1

根据我上面的评论，您可能应该使用对象而不是多维数组。这是一个例子(想象一下你的附加属性，如 name 和 IMage 包括在内，我没有包括在内是为了减少输入)

var arr = [
    { price: 12, something: 'a b c' },
    { price: 8, something: 'a b c' },
    { price: 45, something: 'a b c' },
    { price: 10, something: 'a b c' }
];

arr.sort(function(a, b) { return a.price - b.price; });

/*
    arr is now:

    [ 
        { price: 8, something: 'a b c' },
        { price: 10, something: 'a b c' },
        { price: 12, something: 'a b c' },
        { price: 45, something: 'a b c' } 
    ]
