So, I am trying to pull the volume info from the JSON array from the URL provided: https://www.googleapis.com/books/v1/volumes?q=HTML5
Trying to pull author, title, images, page numbers and description.
This specific class of my HTML code I want to put the JSON data that I have mentioned above in is the 'b-card' class:
<div class="booklist">
<div class="booklist-cards">
<div class="b-card">
</div>
<div class="b-card">
</div>
<div class="b-card">
</div>
<div class="b-card">
</div>
<div class="b-card">
</div>
<div class="b-card">
</div>
<div class="b-card">
</div>
<div class="b-card">
</div>
</div>
</div>
<script src="https://www.googleapis.com/books/v1/volumes?q=HTML5"></script>
<script src="assets/js/script.js"></script>
The script.js file I have tried is below:
function handleResponse(obj) {
const book = Objects.keys(obj).map(item => obj['items']).reduce(
(acc, rec, id, array) => {
let singleBookCover = rec[id].volumeInfo.imageLinks.thumbnail;
let singleBookTitle = rec[id].volumeInfo.title;
let singleBookAuthor = rec[id].volumeInfo.authors[0];
return [...acc, {singleBookCover, singleBookTitle, singleBookAuthor}]
},
[]
).forEach( item => {
let title = document.createElement('h1');
title.textContent = `${item.singleBookTitle}`;
let author = document.createElement('strong');
author.textContent = `${item.singleBookAuthor}`;
let img = document.createElement('img');
img.src = item.singleBookCover;
img.alt = `${item.singleTitle} by ${item.singleBookAuthor}`;
let container = document.getElementsByClassName('b-card');
container.appendChild(title).appendChild(author).appendChild(img);
})
return book
}
The above code only adds the title image and author, but I cant get them to load into my HTML. What are ways to resolve this? Am i calling the URL correctly in the HTML script tag?
Forgot to mention - would like to achieve this without using JQuery & AJAX. I have also tried inputting the callback to handleResponse in the script tag url but it doesnt work.
you can't append to the HTML because container is array so it need index of the element
container[index].appendChild(title).appendChild(author).appendChild(img);
but here simple version, and don't forget to add &callback=handleRespons to the API URL
function handleResponse(obj) {
obj.items.forEach((item, index) => {
if(index > 7) return; // limit 8 result
let div = document.createElement('div');
div.className = 'b-card';
div.innerHTML = `<h1>${item.volumeInfo.title}</h1>
<p><strong>${item.volumeInfo.authors[0]}</strong></p>
<img src="${item.volumeInfo.imageLinks.thumbnail}" alt="${item.singleTitle} by ${item.volumeInfo.authors[0]}" />`
let container = document.querySelector('.booklist-cards');
container.append(div);
})
}<div class="booklist">
<div class="booklist-cards">
</div>
</div>
<script src="//www.googleapis.com/books/v1/volumes?q=HTML5&callback=handleResponse" async></script>
