Question

我想按字母顺序对jJSON表进行排序，并使用data.fuelState（float）的值在第二级进行排序。我设法按字母顺序排序（感谢stackoverflow :)）..如何做到这一点？

Answer 1

您只需在“==”案例中为主要排序参数添加辅助排序逻辑。

var lst = [
    {a:"abc", b:{c:1.5}},
    {a:"abcd", b:{c:1.4}},
    {a:"abcd", b:{c:1.6}},
    {a:"abc", b:{c:1.3}}
];
lst.sort(function(x, y) {
    if(x.a == y.a) {
        if(x.b.c == y.b.c) {
            return 0;
        } else if(x.b.c < y.b.c) {
            return -1;
        } else {
            return 1;
        }
    } else if(x.a < y.a) {
        return -1;
    } else {
        return 1;
    }
});
for(var k in lst) {
    console.log(lst[k].a + " " + lst[k].b.c);
}

Answer 2

将您的JSON转换为JavaScript对象（JSON.parse）：

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse

然后使用数组原型排序对需要排序的任何字段进行排序。

看起来JQuery为你做了解析 - 我没注意到它最初是JQuery。我倾向于将$变量用于我自己的库。
