从JSON获取对象

Question

I am trying to get a specific object from my json response. My response looks like this

var list = [{
"count": 1,
"next": null,
"previous": null,
"results": [
    {
        "id": 9,
        "title": "11",
        "description": "111",
    }
  ]
   }];
var products = list.results;
console.log(products)

The result in the console logs says that the object is undefined. What am I doing wrong here?

Answer 1

list不是JSON（因为JSON是字符串），它是一个数组，因此您必须采用第一个元素：

var products = list[0].results;

Answer 2

List is an array use the array index to select the result

list[0].results;

 var list = [{ "count": 1, "next": null, "previous": null, "results": [ { "id": 9, "title": "11", "description": "111", } ] }]; var products = list[0].results; console.log(products) 

Answer 3

Your JSON was located at 0th index in that array. so simply call your array with index instead calling without index.

 var list = [{ "count": 1, "next": null, "previous": null, "results": [ { "id": 9, "title": "11", "description": "111", } ] }]; var products = list[0]; console.log(products.results)
