How to access a specific property within a nested but fixed structure of arrays and objects-CodePudding

This is my array

let result=[
  { lon: -122.08, lat: 37.39 },
  [ { id: 800, main: 'Clear', description: 'clear sky', icon: '01d' } ],
  'stations',
  {
    temp: 282.55,
    feels_like: 281.86,
    temp_min: 280.37,
    temp_max: 284.26,
    pressure: 1023,
    humidity: 100
  },
  16093,
  { speed: 1.5, deg: 350 },
  { all: 1 },
  1560350645,
  {
    type: 1,
    id: 5122,
    message: 0.0139,
    country: 'US',
    sunrise: 1560343627,
    sunset: 1560396563
  },
  -25200,
  420006353,
  'Mountain View',
  200
]

I want to fetch icon property, so I tried this

for (let i in result) {
    if (i == 1) {
        console.log(result[i]['icon']);
    }
}

But I got "undefined" as an output. please help me access the icon property in this array.

CodePudding user response：

It is not recommended to use for..in with arrays. As result is an array, then you can use index to fetch the icon property as:

result[1][0].icon

let result = [
  { lon: -122.08, lat: 37.39 },
  [{ id: 800, main: "Clear", description: "clear sky", icon: "01d" }],
  "stations",
  {
    temp: 282.55,
    feels_like: 281.86,
    temp_min: 280.37,
    temp_max: 284.26,
    pressure: 1023,
    humidity: 100,
  },
  16093,
  { speed: 1.5, deg: 350 },
  { all: 1 },
  1560350645,
  {
    type: 1,
    id: 5122,
    message: 0.0139,
    country: "US",
    sunrise: 1560343627,
    sunset: 1560396563,
  },
  -25200,
  420006353,
  "Mountain View",
  200,
];

const res = result[1][0].icon;

console.log(res);
