Experiencing difficulty extracting information from an entity

I'm struggling to comprehend the genre data format.

"data":
  "genres": [
    {
      "id": 0,
      "type": "string",
      "name": "string",
      "url": "string"
    },
    {
      "id": 1,
      "type": "string",
      "name": "string",
      "url": "string"
    }
  ],
}

My goal is to show it as: name1, name2, name3 and ideally, I'd like each name to link to its respective URL.

My attempt to access the data has been by

var genres = data.genres;

However, all I get in return is [object Object],[object Object]. I assume that I need to extract the data from these objects, but I'm unsure how to do so.

Answer №1

To better grasp the concept, understand that within the object "data," there exists a property called "genres." This "genres" property holds an array of objects. With this knowledge, you can easily access the data as follows:

const name1 = data.genres[0].name; // Retrieves the first name
const name2 = data.genres[1].name; // Retrieves the second name

If you wish to iterate through the genre data, you must loop through the objects within the "genres" property:

data.genres.map((genre) => console.log(genre.name)); // Displays all names

A common example scenario would be:

for (let i = 0; i < data.genres.length; i++) {
    const name = data.genres[i].name;
    console.log(name); // Outputs the names
}

To iterate through the data and generate links, you will need to use a loop and create anchor elements for each link. Make sure to have a container element where you can attach the links:

const mainContainer = document.getElementById("container");
var categories = data.categories;
categories.forEach(category => { 
    var lnkCategory = document.createElement("a"); 
    lnkCategory.textContent = category.name;
    lnkCategory.href = category.url;

You also have the option of adding classes or ids to the links:

    lnkCategory.classList.add("customClass");
    lnkCategory.id = category.id;
    mainContainer.appendChild(lnkCategory);
});
