How to implement AJAX request array

This time I will show you how to implement the AJAX request array, and what are the precautions for the AJAX request array. The following is a practical case, let's take a look.

Everyone should have discovered that when we send an AJAX request with an array in the data, it cannot be directly placed in the data and sent to the background like ordinary JSON data.

For example There is such a data that needs to be sent to the background:

{
  "orderId": 22,
  "resourceJson": [
    {
      "carCapacity": 223,
      "carNumber": "123",
      "driverInfo": "123",
      "failReason": "3123123",
      "id": 25,
      "ispass": 0,
      "lineId": 784,
      "load_plan": "123",
      "onPackageDay": 123,
      "price": 123,
      "storeOutCapacity": 123,
      "store_out_capacity": 123
    },
    {
      "failReason": "31231231",
      "id": 2,
      "ispass": 0,
      "lineId": 787,
      "load_plan": "123",
      "store_out_capacity": 123,
      "tallyman": "ddd"
    },
    {
      "failReason": "123123",
      "id": 1,
      "ispass": 0,
      "lineId": 785,
      "load_plan": "123",
      "store_out_capacity": 123,
      "tallyman": "fff"
    }
  ]
}

The resourceJson field is an array. If you directly pass this JSON data to the background

The data obtained by the background is this Looks like:

The browser will automatically decompose the array into individual

variables, and it will be stupid to get this data in the background.

So, the best way is to program the array

String, very simple, store the array in a separate variable, and thenJSON.stringify (array), put the obtained string into JSON data, so that the browser will not automatically deconstruct the array for you, and what you get in the background is a real array.

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
