javascript - 使用javascript在对象数组中查找值

Question

鉴于以下情况:

var myArray = [
  { 
    id: "3283267",
    innerArray: ["434","6565","343","3665"]
  },
  {
    id: "9747439",
    innerArray: ["3434","38493","4308403840","34343"]
  },
  {
    id: "0849374",
    innerArray: ["343434","57575","389843","38493"]
  }
];

我如何搜索 myArray 中的对象以确定字符串“38493”是否存在于 innerArray 中，然后返回一个包含对象 ID 的新数组....像这样:

var arrayWithIds = ["9747439", "0849374"];

Answer 1

使用 Array.forEach 和 Array.indexOf 函数的简单解决方案:

var search =  "38493", 
    result = [];

myArray.forEach(function(o) {
     if (o.innerArray.indexOf(search) !== -1) this.push(o.id);   
}, result);

console.log(result);  // ["9747439", "0849374"]
