Question

有人可以帮我一些代码，将数据插入到现有的对象数组中，这样我就拥有了这个数组

[
  {
    "order_id": "241918",
    "customer_name": "Marietjie",
    "customer_surname": "Short",
    "total_items": "44",
    "completed_items": "17",
    "percent_complete": 0.38636363636364,
    "datetime_received": "2018-07-25 15:18:25",
    "delivery_date": "2018-10-29",
    "delivery_from": "12:00",
    "delivery_to": "13:00",
    "completed": "0",
    "shopper": "joel"
  },
  {
    "order_id": "281774",
    "customer_name": "Ashleigh",
    "customer_surname": "Hodge",
    "total_items": "16",
    "completed_items": "0",
    "percent_complete": 0,
    "datetime_received": "2018-10-04 15:59:19",
    "delivery_date": "2018-10-29",
    "delivery_from": "12:00",
    "delivery_to": "13:00",
    "completed": "0",
    "shopper": null
  }
]

我想将此数组中的数据插入上方的数组，以将percent_completed的值替换为下方的数组的值。

["17", "0"]

Answer 1

const array =[
  {
    "order_id": "241918",
    "customer_name": "Marietjie",
    "customer_surname": "Short",
    "total_items": "44",
    "completed_items": "17",
    "percent_complete": 0.38636363636364,
    "datetime_received": "2018-07-25 15:18:25",
    "delivery_date": "2018-10-29",
    "delivery_from": "12:00",
    "delivery_to": "13:00",
    "completed": "0",
    "shopper": "joel"
  },
  {
    "order_id": "281774",
    "customer_name": "Ashleigh",
    "customer_surname": "Hodge",
    "total_items": "16",
    "completed_items": "0",
    "percent_complete": 0,
    "datetime_received": "2018-10-04 15:59:19",
    "delivery_date": "2018-10-29",
    "delivery_from": "12:00",
    "delivery_to": "13:00",
    "completed": "0",
    "shopper": null
  }
];
const array1= ["17","12"];

result = array1.map((value, index) => {

return { ...array[index], completed_items: value };
});
console.log(result);

Answer 2

您只需要迭代原始数据数组，并使用提供的更新数组中的相应值覆盖其属性即可。像这样：

PreferenceFragment

Answer 3

在包含新值和包含数据的数组上循环（当到达其中一个的末尾时，循环将停止），然后在每次迭代时更新一个数据。

CREATE TYPE name_type AS ENUM('name1', 'name2');

CREATE TABLE Employee2(
    ID integer, 
    myname name_type
);

Answer 4

尝试一下：

	var array=[
  {
    "order_id": "241918",
    "customer_name": "Marietjie",
    "customer_surname": "Short",
    "total_items": "44",
    "completed_items": "17",
    "percent_complete": 0.38636363636364,
    "datetime_received": "2018-07-25 15:18:25",
    "delivery_date": "2018-10-29",
    "delivery_from": "12:00",
    "delivery_to": "13:00",
    "completed": "0",
    "shopper": "joel"
  },
  {
    "order_id": "281774",
    "customer_name": "Ashleigh",
    "customer_surname": "Hodge",
    "total_items": "16",
    "completed_items": "0",
    "percent_complete": 0,
    "datetime_received": "2018-10-04 15:59:19",
    "delivery_date": "2018-10-29",
    "delivery_from": "12:00",
    "delivery_to": "13:00",
    "completed": "0",
    "shopper": null
  }
]

var array2=["17", "0"];

for(var x=0; x< array.length; x++){
	array[x].percent_complete=array2[x]
}

console.log(array)
