使用Array.prototype.filter（）函数。

JSON

var jsonObj =[
 {
  "name": "Me",
  "info": {
   "age": "15",
   "favColor": "Green",
   "pets": true
  }
 },
 {
  "name": "Alex",
  "info": {
   "age": "16",
   "favColor": "orange",
   "pets": false
  }
 },
{
  "name": "Kyle",
  "info": {
   "age": "15",
   "favColor": "Blue",
   "pets": false
  }
 }
];

过滤器

var getPerson = function(name){
    return jsonObj.filter(function(obj) {
      return obj.name === name;
    });
}

查找数组索引的方法：

index = myArray.map((i) => i.id).indexOf(value_of_id);
item = myArray[index];

最短，

var theAnswerObj = _.findWhere(array, {id : 42});

下面的代码将帮助您从数据中的嵌套对象中搜索值。

const updatedData = myArrayOfObjects.filter((obj: any) => Object.values(obj).some((val: any) => {
   if (typeof (val) == typeof ("str")) {
      return val.toString().includes(Search)
   } else {
      return Object.values(val).some((newval: any) => {
         if (newval !== null) {
            return newval.toString().includes(Search)
         }
      })
   }
}))

我认为最简单的方法是以下方法，但它在Internet Explorer 8（或更早版本）上不起作用：

var result = myArray.filter(function(v) {
    return v.id === '45'; // Filter out the appropriate one
})[0].foo; // Get result and access the foo property

尝试以下操作

function findById(source, id) {
  for (var i = 0; i < source.length; i++) {
    if (source[i].id === id) {
      return source[i];
    }
  }
  throw "Couldn't find object with id: " + id;
}
