How can I interpret my JSON via Google Books API URL and display it on my HTML page using JS?

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>

How do I use For Loop in JavaScript to show the list?

I am a beginner in JavaScript and I can't figure out the following problem: I am trying to create a simple JavaScript Movie List. I have 10 lists on the Movie List. I tried to show all of the lists with for loop, but it doesn't work.
Here's the code:
function renderModal() {
for (let i = 0; i < listMovies.length; i++) {
let movieData = listMovies[i];
document.getElementById("poster").src = movieData.img;
document.getElementById("title").innerHTML = movieData.name;
document.getElementById("genre").innerHTML = movieData.genre;
document.getElementById("rating-num").innerHTML = "Rating: "+ movieData.rating + "/10";
document.getElementById("movie-desc").innerHTML = movieData.desc;
document.getElementById("imdb-page").href = movieData.link;
return movieData;
}
}
What do I have to do?
Help me to fix it!.

You can use template tag for list and render it into target element.I am showing an example.
Movie list
<div id="movieList"></div>
template for list
<template id="movieListTemplate">
<div class="movie">
<img src="" class="poster" alt="">
<div class="title"></div>
<div class="genre"></div>
<div class="rating-num"></div>
<div class="movie-desc"></div>
<div class="imdb-page"></div>
</div>
</template>
Javascript code:
if (listMovies.length > 0) {
const movileListTemplate = document.getElementById('movieListTemplate')
const movieRenederElement = document.getElementById('movieList')
for(const movie of listMovies) {
const movieEl = document.importNode(movileListTemplate.content, true)
movieEl.querySelector('.poster').src = movie.img
movieEl.querySelector('.title').textContent = movie.name
//use all queryselector like above
}
}

Your return movieData; will stop the loop dead. Not that running it more than once will change anything since you change the same elements over and over. IDs must be unique.
Here is a useful way to render an array
document.getElementById("container").innerHTML = listMovies.map(movieData => `<img src="${movieData.img}" />
<h3>${movieData.name}</h3>
<p>${movieData.genre}</p>
<p>Rating: ${movieData.rating}/10</p>
<p>${movieData.desc}
IMDB
</p>`).join("<hr/>");

With return movieData, the for loop will ends in advance.You should put it outside the for loop.

Already known weather for city should not repeat again

I'm trying my first weather api APP. Here I'm trying to achive that if the city weather is already displayed , It should give the message "You already know the weather" . and should not repeat the weather
Here is my code. Anyone Please look at my code ...
What is the mistake I have been made.
<div class="main">
<div class="container">
<div class="search_por">
<h2>Weather </h2>
<div class="validate_msg color_white"></div>

fetch(url,{method:'GET'})
.then(response=>response.json())
.then(data=>{console.log(data)
const{main,sys,weather,wind}=data;
//icons-end
var error_ms=document.getElementsByClassName("validate_msg")[0];
var iconcode = weather[0].icon;
console.log(iconcode);
var li=document.createElement("Li");
var weatherinfo=`<div class="nameci font_40" data-name="${data.name},${sys.country}"><span>${data.name}</span><sup>${sys.country}</sup></div>

`;
li.innerHTML=weatherinfo;
var ulid=document.getElementById("list_it");
ulid.appendChild(li);
var city_name=data.name;
console.log(skycons);
var listitems=document.querySelectorAll('#list_it');
const listArray=Array.from(listitems);
if(listArray.length>0)
{
var filtered_array=listArray.filter(el=>{

});
var error_ms=document.getElementsByClassName("validate_msg")[0];
error_ms.innerHTML="";
//var get_text=document.querySelector("form");
get_text.reset();
});
My full code is here:
https://codepen.io/pavisaran/pen/wvJaqBg

Let's try keeping track of a list of displayed locations outside of the callback:
var get_text = document.querySelector("form");
// Keep Track Of Displayed Cities Here Instead
let displayed = [];
get_text.addEventListener("submit", e => {
e.preventDefault();
var input_val = document.querySelector('input').value;
const apiKey = "bc4c7e7826d2178054ee88fe00737da0";
const url = `https://api.openweathermap.org/data/2.5/weather?q=${input_val}&appid=${apiKey}&units=metric`;
fetch(url, {method: 'GET'})
.then(response => response.json())
.then(data => {
var error_ms = document.getElementsByClassName("validate_msg")[0];
const {main, sys, weather, wind, name} = data;
if (displayed.length > 0) {
// Filter Displayed Based on Current vs name from data (response)
const filtered_array = displayed.filter(el => el === name);
if (filtered_array.length > 0) {
error_ms.innerHTML = "You Already know the weather of this country....";
get_text.reset();
return Promise.resolve();
}
}
// Add City To Array of Displayed Cities
displayed.push(name);
// Do Rest of Code to Add New City
var iconcode = weather[0].icon;
var li = document.createElement("Li");
var weatherinfo = `<div class="nameci font_40" data-name="${data.name},${sys.country}"><span>${data.name}</span><sup>${sys.country}</sup></div>
<div class="temp_ic">
<img class="weat_icon" src="http://openweathermap.org/img/w/${iconcode}.png">
<div class="deg">${Math.floor(main.temp)}<sup>o</sup></div>
</div>
<div class="clear">
<div>${weather[0].description}</div>
</div>
`;
li.innerHTML = weatherinfo;
var ulid = document.getElementById("list_it");
ulid.appendChild(li);
})
.catch((error) => {
error_ms.innerHTML = "Please Enter a valid city Name";
});
var error_ms = document.getElementsByClassName("validate_msg")[0];
error_ms.innerHTML = "";
get_text.reset();
});

You have to just check for the value which is coming from api whether it's present on your list or not. you can try this.
li.innerHTML=weatherinfo;
var ulid=document.getElementById("list_it");
var isPresent = false;
var items = ulid.getElementsByTagName("li");
for (var i = 0; i < items.length; i++){
if(items[i].innerHTML == li.innerHTML){
alert("you already know the weather")
isPresent = true;
}
}
if(!isPresent){
ulid.appendChild(li);
}

Can't print correct innerHTML message within a nested function

I'm working on a recipes page where you have a series of buttons and posts that are interconnected. The buttons have names of recipe categories such as Pie and Cake. When you click on a 'Pie' button, you are only shown the posts that are categorized as 'Pie'. Both the buttons and the posts have data attributes that have their recipe category on there.
I am able to get this to work, however, I'm having issues for when you click on a recipe category button, and there are no corresponding posts. For this, I created an empty '#message' div that would output a message if there were no recipe posts found, and an empty string if there were recipe posts.
When I click on a recipe button that does have posts, I get the 'No Recipes' text in the message. Also weird that it looks like it's applying the correct message only to the last button/post which in this example is 'Cake'.
Can someone explain why this is not working? I get it's probably a scope/closure issue, but I'm unsure what's going on.
//BUTTONS
<section>
<button class="recipe_button" data-btncategory="Pie">
Pie
</button>
<button class="recipe_button" data-btncategory="Cake">
Cake
</button>
</section>
//POSTS
<div id="message"></div>
<section class="recipe" data-postcategory="Pie">
<h2>Pie Recipe</h2>
</section>
<section class="recipe" data-postcategory="Cake">
<h2>Cake Recipe</h2>
</section>
let posts = document.querySelectorAll(".recipe");
let postsArr = Array.from(posts);
let btn = document.querySelectorAll(".recipe_button");
let btnArray = Array.from(btn);
let message = document.getElementById("message");
btnArray.forEach((button) => {
button.onclick = (el) => {
let match = el.target.dataset.btncategory;
postsArr.filter(function(post, i) {
if (post.dataset.postcategory == match) {
posts[i].style.display = "grid";
<-- message not working properly -->
message.innerHTML = "";
} else {
posts[i].style.display = "none";
<-- message not working properly -->
message.innerHTML = "Sorry No Recipes Available";
}
});
}
});

look at how your filter is running. you'll always get ones that match and ones that don't - so both the if and the else code will always run
What you want to do is hide/display posts in the filter, returning true for displayed and false when hidden
That way, the resulting array length will be 0 if no match, and 1 or more if there is a match
Then another if/else after determining if there is anything displayed to show/hide the message
let posts = document.querySelectorAll(".recipe");
let postsArr = Array.from(posts);
let btn = document.querySelectorAll(".recipe_button");
let btnArray = Array.from(btn);
let message = document.getElementById("message");
btnArray.forEach((button) => {
button.onclick = (el) => {
let match = el.target.dataset.btncategory;
let found = postsArr.filter(function(post) {
if (post.dataset.postcategory == match) {
post.style.display = "grid";
return true;
} else {
post.style.display = "none";
return false;
}
}).length;
message.innerHTML = found ? "" : "Sorry No Recipes Available";
}
});
<section>
<button class="recipe_button" data-btncategory="Pie">
Pie
</button>
<button class="recipe_button" data-btncategory="Cake">
Cake
</button>
</section>
//POSTS
<div id="message"></div>
<section class="recipe" data-postcategory="Pie">
<h2>Pie Recipe</h2>
</section>
<section class="recipe" data-postcategory="Cake">
<h2>Cake Recipe</h2>
</section>
Having said all that, the message would NEVER display Sorry No Recipes Available since your buttons guarantee that there will be one displayed

Here's a straightforward way to make your idea work.
It uses an event listener with event delegation.
See the in-code comments for further clarifications.
// Identifies DOM elements
const
btnsDiv = document.getElementById("btns"),
posts = [...document.getElementsByClassName("recipe")],
message = document.getElementById("message");
// Calls `filterPosts` when btnsDiv is clicked
btnsDiv.addEventListener("click", filterPosts);
// Defines `filterPosts`
function filterPosts(event){
// Ignores irrelevant clicks
if(!event.target.classList.contains("btn")){ return; }
// Shows message while there is no match
let match = false;
message.classList.remove("hidden");
// Remembers category
const category = event.target.dataset.category;
// Iterates through recipes
posts.forEach( (post) => {
// Hides recipe until it matches
post.classList.add("hidden");
// If recipe matches, shows it and notes the match
if(post.dataset.category == category) {
post.classList.remove("hidden");
match = true;
}
});
// If any match occurred, hides message
if(match == true){
message.classList.add("hidden");
}
}
.hidden{ display: none; }
<div id = "btns">
<button class="btn" data-category="Pie">Pie </button>
<button class="btn" data-category="Cake"> Cake </button>
<button class="btn" data-category="Pasta"> Pasta </button>
</div>
<div id="message" class="hidden">Sorry No Recipes Available</div>
<div class="recipe hidden" data-category="Pie">
<h2>Pie Recipe 1</h2>
</div>
<div class="recipe hidden" data-category="Cake">
<h2>Cake Recipe 1</h2>
</div>
<div class="recipe hidden" data-category="Cake">
<h2>Cake Recipe 2</h2>
</div>

Google Books API: Cannot read property 'thumbnail' of undefined

I'm doing a simple project, using Google Books API and encountered with the following error:Cannot read property 'thumbnail' of undefined. It seems, that for some queries there is no image or path to it. For example, for books query it works OK and shows related books.
While for great query, it throws an error.
As far as I understood there are not book cover in Google Books API for sme books, and that is why it throws the error. I am trying to fix it with help of lodash library, namely _set function.
document.querySelector('.search-book').addEventListener('click', getBook);
var titleHolder = document.querySelector('.title');
var columns = document.querySelector('.is-parent');
var total = '';
const apiKey = 'AIzaSyCu0GO52L8knIMQ7P_gmazBf_7wlngXqyc';
function getBook() {
var search = document.querySelector('#input').value;
console.log(search);
fetch(
`https://www.googleapis.com/books/v1/volumes?q=${search}:keyes&key=${apiKey}`
)
.then(function(res) {
return res.json();
})
.then(function(data) {
//console.log(data.items);
let items = data.items;
for (var i = 0; i < items.length; i++) {
// Volume info
let item = items[i].volumeInfo;
// Author
let author = item.authors;
// Image link
var imgLink = item.imageLinks.thumbnail;
// Title
let title = item.title;
// Description
let desc = item.description;
if (typeof desc === 'undefined') {
desc = 'No description available';
}
if (typeof author === 'undefined') {
author = 'No author';
}
if (!item.imageLinks.firstChild) {
_.set(
item,
'item.imageLinks',
'thumbnail:https://bulma.io/images/placeholders/128x128.png'
);
console.log(data);
}
total += `
<div class=" card tile is-child is-3 box">
<div class="card-image">
<figure class="image is-4by3">
<img src="${imgLink}" alt="Placeholder image">
</figure>
</div>
<div class="card-content">
<p class="title is-6 has-text-primary has-text-centered is-capitalized">${title}</p>
<p class="title is-6 has-text-primary has-text-centered is-capitalized">${author}</p>
<p class="has-text-black-ter has-text-weight-normal">${desc.slice(
0,
150
) + '...'}</p>
</div>
</div>
`;
console.log(item);
}
columns.innerHTML = total;
});
}
First of all I check if there is a thumbnail property in object, if there is not such property, I use lodash _set function to substitute absent image with placeholder, but does not work. Please could help me with this issue. Either with loadsh function or suggest me another way out.
if (!item.imageLinks.firstChild) {
_.set(
item,
'item.imageLinks',
'thumbnail:https://bulma.io/images/placeholders/128x128.png'
);
console.log(data);
}

i've spent way too much time trying to fix this.
this is how i did it, now it doesn't throw any errors, finally
src={
book.volumeInfo.imageLinks === undefined
? ""
: `${book.volumeInfo.imageLinks.thumbnail}`
}
