根据条件从数组中获取一项

Question

I have an array with different values (in JSON structure), I need to get one item on the array based on another value.

This is what I did so far:

var orders= [{
    "id": 1,
    "order": "11"
  },
  {
    "id": 2,
    "order": "22"
  },
  {
    "id": 3,
    "order": "33"
  }];
var order = $.grep(orders, function (e) { return e.order === '22'; })[0];
var orderID = order ? order.id : 0;

Is this the simplest way to do it?

With ES6, you could use Array#find

 var orders= [{ id: 1, order: "11" }, { id: 2, order: "22" }, { id: 3, order: "33" }], order = orders.find(o => o.order === "22"), orderID = order ? order.id : 0; console.log(orderID);
