javascript - How can I append data in an array from list using native javascript

问题描述

I am calling data from API and listing the data by name. I want to search and add object by name from the list (using Add Fav Movie button) and store the entire data of that object in an array using native javascript.

I can do this in Angularjs , but less idea using native 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);

On response JSON I want to select object of movie (which I click on list ) under array key result. And append that particular movie object on another array. How can I do this ?

解决方案

当您在 input（最喜欢的电影）中输入电影名称并点击 时submit，检查输入是否有任何值。如果有，则制作textContent您最喜欢的电影列表的数组，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);
    }
});
<header id="main-header" class="bg-success text-white p-4 mb-3">
    <div class="container">
        <h1 id="header-title">Get Movies<span style="display:none">123</span></h1>
        <input style="align:right" type="text" class="form-control mr-2" id="search">
        <input type="submit" class="btn btn-dark" value="Search" id="button">
    </div>
</header>
<div class="container">
    <div id="main" class="card card-body">
        <h2 class="title">Add Fav Movies</h2>
        <form class="form-inline mb-3">
            <input type="text" class="form-control mr-2">
            <input type="submit" class="btn btn-dark" value="Submit">
        </form>
        <h2 class="title">Lists</h2>
        <ul id="items" class="list-group">

        </ul>
    </div>
