Issue
Below is my code and I am getting movies data from an API and I am creating different elements using Javascript create Element like title, rating and favorite radio button for selecting favorite movies now I wonder how to target all the selected radio buttons because I have generated radio buttons dynamically and its getting very hard to target those radio buttons:
const SEARCHAPI = "https://api.themoviedb.org/3/search/movie?&api_key=04c35731a5ee918f014970082a0088b1&query=";
const apiUrl = 'https://api.themoviedb.org/3/discover/movie?sort_by=popularity.desc&api_key=04c35731a5ee918f014970082a0088b1&page=1';
const IMGPATH = "https://image.tmdb.org/t/p/w1280";
const main = document.getElementById("main");
const form = document.getElementById("form");
const search = document.getElementById("search");
showMovies(apiUrl);
function showMovies(url) {
fetch(url)
.then((res) => res.json())
.then(function(data) {
console.log(data.results);
data.results.forEach((element) => {
let movYear = new Date(element.release_date);
const el = document.createElement("div");
const image = document.createElement("img");
const title = document.createElement("h2");
const year = document.createElement("h2");
const rank = document.createElement("h2");
const node = document.createTextNode("Favrouite: ")
const wrapper = document.createElement("h2");
const fav = document.createElement("INPUT");
fav.setAttribute("type", "radio");
fav.setAttribute("id", element.id);
wrapper.insertBefore(node, wrapper.children[0]);
wrapper.appendChild(fav);
title.innerHTML = `Title: ${element.title}`;
year.innerHTML = `Release: ${movYear.getFullYear()}`;
rank.innerHTML = `Rating: ${element.popularity}`;
image.src = IMGPATH + element.poster_path;
el.appendChild(image);
el.appendChild(title);
el.appendChild(year);
el.appendChild(rank);
el.appendChild(wrapper);
main.appendChild(el);
});
});
}
form.addEventListener("submit", (e) => {
e.preventDefault();
main.innerHTML = "";
let searchTerm = search.value;
if (searchTerm) {
showMovies(SEARCHAPI + searchTerm)
search.value = "";
} else if (!searchTerm) {
showMovies(apiUrl)
} else {
main.innerHTML = "<h1>No result Found!</h1>";
}

You can delegate
const title = document.createElement("h2");
title.classList.add("title");
fav.setAttribute("type", "radio");
fav.setAttribute("id", element.id);
fav.classList.add("fav")
main.addEventListener("click",function(e) {
const tgt = e.target;
if (tgt.matches(".fav")) {
console.log(tgt.closest("div").querySelector("h2.title").textContent);
}
})
To get all the favourites, you can use a map:
const allFavs = [...main.querySelectorAll(".fav:checked")].map(rad => rad.closest("div").querySelector("h2.title").textContent);
const SEARCHAPI = "https://api.themoviedb.org/3/search/movie?&api_key=04c35731a5ee918f014970082a0088b1&query=";
const apiUrl = 'https://api.themoviedb.org/3/discover/movie?sort_by=popularity.desc&api_key=04c35731a5ee918f014970082a0088b1&page=1';
const IMGPATH = "https://image.tmdb.org/t/p/w1280";
const main = document.getElementById("main");
const form = document.getElementById("form");
const search = document.getElementById("search");
main.addEventListener("click",function(e) {
const tgt = e.target;
if (tgt.matches(".fav")) {
console.log("clicked",tgt.closest("div").querySelector("h2.title").textContent);
const allFavs = [...main.querySelectorAll(".fav:checked")].map(rad => rad.closest("div").querySelector("h2.title").textContent);
console.log("current favs",allFavs)
}
})
showMovies(apiUrl);
function showMovies(url) {
fetch(url)
.then((res) => res.json())
.then(function(data) {
// console.log(data.results);
data.results.forEach((element) => {
let movYear = new Date(element.release_date);
const el = document.createElement("div");
const image = document.createElement("img");
const title = document.createElement("h2");
title.classList.add("title");
const year = document.createElement("h2");
const rank = document.createElement("h2");
const node = document.createTextNode("Favourite: ")
const wrapper = document.createElement("h2");
const fav = document.createElement("INPUT");
fav.setAttribute("type", "radio");
fav.setAttribute("id", element.id);
fav.classList.add("fav")
wrapper.insertBefore(node, wrapper.children[0]);
wrapper.appendChild(fav);
title.innerHTML = `Title: ${element.title}`;
year.innerHTML = `Release: ${movYear.getFullYear()}`;
rank.innerHTML = `Rating: ${element.popularity}`;
image.src = IMGPATH + element.poster_path;
el.appendChild(image);
el.appendChild(title);
el.appendChild(year);
el.appendChild(rank);
el.appendChild(wrapper);
main.appendChild(el);
});
});
}
form.addEventListener("submit", (e) => {
e.preventDefault();
main.innerHTML = "";
let searchTerm = search.value;
if (searchTerm) {
showMovies(SEARCHAPI + searchTerm)
search.value = "";
} else if (!searchTerm) {
showMovies(apiUrl)
} else {
main.innerHTML = "<h1>No result Found!</h1>";
}
});img { height: 150px }<header>
<a href="index.html">
<h1>Movies</h1>
</a>
<form id="form" name="form" autocomplete="off">
<input type="text" id="search" placeholder="Search" class="search" autofocus />
<button type="submit">Submit</button>
</form>
</header>
