我在JavaScript中有上面的对象，它没有正确排序。我该如何解决这个问题？

Answer 1

var arr = [{
    gradeName: "A+",
    gradeMaxMarks: "89",
    gradeMinMarks: "80"
  },
  {
    gradeName: "A",
    gradeMaxMarks: "79",
    gradeMinMarks: "70"
  },
  {
    gradeName: "B+",
    gradeMaxMarks: "69",
    gradeMinMarks: "60"
  },
  {
    gradeName: "B",
    gradeMaxMarks: "59",
    gradeMinMarks: "55"
  },
  {
    gradeName: "C",
    gradeMaxMarks: "49",
    gradeMinMarks: "40"
  },
  {
    gradeName: "D",
    gradeMaxMarks: "39",
    gradeMinMarks: "30"
  },
  {
    gradeName: "A++",
    gradeMaxMarks: "100",
    gradeMinMarks: "90"
  }
]

arr.sort((a,b) => Number(b.gradeMaxMarks)-Number(a.gradeMaxMarks))
console.log(arr)

Answer 2

您似乎忘记了脚本的sort部分。

＆＃13;

const input = [{
    gradeName: "A+",
    gradeMaxMarks: "89",
    gradeMinMarks: "80"
  },
  {
    gradeName: "A",
    gradeMaxMarks: "79",
    gradeMinMarks: "70"
  },
  {
    gradeName: "B+",
    gradeMaxMarks: "69",
    gradeMinMarks: "60"
  },
  {
    gradeName: "B",
    gradeMaxMarks: "59",
    gradeMinMarks: "55"
  },
  {
    gradeName: "C",
    gradeMaxMarks: "49",
    gradeMinMarks: "40"
  },
  {
    gradeName: "D",
    gradeMaxMarks: "39",
    gradeMinMarks: "30"
  },
  {
    gradeName: "A++",
    gradeMaxMarks: "100",
    gradeMinMarks: "90"
  }
];

input.sort((a, b) => b.gradeMaxMarks - a.gradeMaxMarks);
console.log(input);

Answer 3

使用Javascript的Array.sort()方法对降序 [100,80,60,40，....]（您的要求）中的数组进行排序，如下所示：< / p>

array.sort(function(a, b) {
  return b.gradeMaxMarks - a.gradeMaxMarks;
});

如果你想在升序 [10,20,40,45,60 ......]中对数组进行排序，那就这样做：

array.sort(function(a, b) {
  return a.gradeMaxMarks - b.gradeMaxMarks;
});

以下是工作代码段：

＆＃13;

var array = [{gradeName:"A+",gradeMaxMarks:"89",gradeMinMarks:"80"},{gradeName:"A",gradeMaxMarks:"79",gradeMinMarks:"70"},{gradeName:"B+",gradeMaxMarks:"69",gradeMinMarks:"60"},{gradeName:"B",gradeMaxMarks:"59",gradeMinMarks:"55"},{gradeName:"C",gradeMaxMarks:"49",gradeMinMarks:"40"},{gradeName:"D",gradeMaxMarks:"39",gradeMinMarks:"30"},{gradeName:"A++",gradeMaxMarks:"100",gradeMinMarks:"90"}];

array.sort(function(a, b) {
  return b.gradeMaxMarks - a.gradeMaxMarks;
});

console.log(array)

对象数据排序不起作用
