从键值最低的JSON数组中获取数组

Question

在如下所示的数组中：

[{
    "sport" : "Cricket",
    "score" : "22.45"
},
{
    "sport" : "Tennis",
    "score" : "-12"
}]

我想迭代JSON并找到得分最低的数组。在这种情况下，获取

{
    "sport" : "Tennis",
    "score" : "-12"
}

Answer 1

根据得分升序排列并返回第一个对象

var a = [{
    "sport": "Cricket",
    "score": "22.45"
  },
  {
    "sport": "Tennis",
    "score": "-12"
  }
];
console.log(a.sort((a, b) => a.score - b.score)[0])

Answer 2

尝试使用此方法从具有最低键值的JSON数组获取数组

let myArray =[{
    "sport" : "Cricket",
    "score" : "22.45"
},
{
    "sport" : "Tennis",
    "score" : "-12"
},
{ "sport" : "Tennis", "score" : "-12000" }]

let minOfArray =myArray.reduce(function(prev, curr) {
    return parseInt(prev.score) < parseInt(curr.score) ? prev : curr;
});

console.log(minOfArray);

Answer 3

您应该使用parseInt：

var arr = [{
    "sport" : "Cricket",
    "score" : "22.45"
},
{
    "sport" : "Tennis",
    "score" : "-12"
},
{
    "sport" : "Tennis",
    "score" : "-12000"
}];

var res = arr.reduce((a,c) => parseInt(c.score) < parseInt(a.score) ? c : a);

Answer 4

您可以使用reduce遍历您的商品并获得最低分：

const data = [{
  "sport" : "Cricket",
  "score" : "22.45"
}, {
  "sport" : "Tennis",
  "score" : "-12"
}];

const result = data.reduce((acc, x) => x.score < acc.score ? x : acc, data[0]);

console.log(result);
