我正在从 API 调用数据并按名称列出数据。我想从列表中按名称搜索和添加对象(使用“添加最喜欢的电影”按钮)并使用 native javascript 将该对象的全部数据存储在数组中。
我可以在 Angularjs 中做到这一点，但不太了解使用原生 javascript。
function addListItem(title, listId) {
var ul = document.getElementById(listId);
var li = document.createElement("li");
li.className = 'list-group-item';
li.appendChild(document.createTextNode(title));
ul.appendChild(li);
}
function afterLoad() {
var data = JSON.parse(this.responseText);
var name = document.createElement('img');
const results = data.results;
// loop through items
results.forEach(item => {
addListItem(item.title, "items");
});
name.src = data.title;
document.body.appendChild(name);
}
function afterClick() {
// changed target to focus search
var terms = document.getElementById("search").value.split(' ').join('+');
var request = new XMLHttpRequest();
request.addEventListener('load', afterLoad);
request.open('GET', 'https://api.themoviedb.org/3/search/movie?api_key=8318c431b4fc8a2c4762bf2a52c351ee&query='+terms);
request.send();
}
button.addEventListener("click", afterClick);<!DOCTYPE html>

最佳答案
当您在 input(最喜欢的电影)中键入电影名称并点击 submit 时，检查输入是否有任何值。如果有，则制作您最喜欢的电影列表的 textContent 数组，然后应用过滤器以获取名称与用户输入的值匹配的电影对象
function addListItem(title, listId) {
var ul = document.getElementById(listId);
var li = document.createElement("li");
li.className = 'list-group-item';
li.appendChild(document.createTextNode(title));
ul.appendChild(li);
}
let results;
function afterLoad() {
var data = JSON.parse(this.responseText);
var name = document.createElement('img');
results = data.results;
// loop through items
results.forEach(item => {
addListItem(item.title, "items");
});
name.src = data.title;
document.body.appendChild(name);
}
function afterClick() {
// changed target to focus search
var terms = document.getElementById("search").value.split(' ').join('+');
var request = new XMLHttpRequest();
request.addEventListener('load', afterLoad);
request.open('GET', 'https://api.themoviedb.org/3/search/movie?api_key=8318c431b4fc8a2c4762bf2a52c351ee&query='+terms);
request.send();
}
button.addEventListener("click", afterClick);
const submitBtn = document.querySelector('input[value="Submit"]');
const favMovie = document.querySelector('form > input');
submitBtn.addEventListener('click', function(e) {
e.preventDefault();
const favMovieName = favMovie.value;
if(favMovieName.length > 0) {
const filteredFavMovies = results.filter(({title}) => title.toLowerCase().includes(favMovieName.toLowerCase()));
console.log(filteredFavMovies);
}
