我有一个对象表，其中有分数和角色名称，我想检索分数最高的索引以便能够制作记分板。这就是我的数组的样子[ { "score": 51, "name": "toto" }, { "score": 94, "name": "tata" }, { "score": 27, "name": "titi" }, { "score": 100, "name": "tutu" }]在这种情况下，我想获得得分最高的人的索引，在这种情况下，指数是3，因为得分最高的是tutu。预先感谢您的帮助

该sort函数应该执行以下操作：
var raw_scores = [
{
"score": 51,
"name": "toto"
},
{
"score": 94,
"name": "tata"
},
{
"score": 27,
"name": "titi"
},
{
"score": 100,
"name": "tutu"
}
]
var sorted_scores = raw_scores.sort(function(a,b){return b.score - a.score})

使用for循环
var index = 0;
var max = 0;
for (var i = 0; i < scores.length; i++) {
if (s[i].score > max) {
max = s[i].score;
index = i;
}
}
console.log(index);

您可以使用该reduce功能
const array = [
{
"score": 51,
"name": "toto"
},
{
"score": 94,
"name": "tata"
},
{
"score": 27,
"name": "titi"
},
{
"score": 100,
"name": "tutu"
}
];
const highestScore = array.reduce((last, item) => {
// return the item if its score is greater than the highest score found.
if(!last || last.score < item.score) {
return item;
}
return last;
});

var data = [{
"score": 51,
"name": "toto"
},
{
"score": 94,
"name": "tata"
},
{
"score": 27,
"name": "titi"
},
{
"score": 100,
"name": "tutu"x
}
];
var max_score = Math.max.apply(Math, data.map(function(o) {
return o.score;
}))
console.log(data.filter(i => i.score === max_score))
