Question

我知道要在AngularJS中重复显示数据，但是现在我正在尝试使用本机javascript。

我从 TMDB API 调用了数据。现在，我需要在UI列表中列出它们。

    function afterLoad() {
    var data = JSON.parse(this.responseText);
    console.log(data);
    name.src = data.title;
    }

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);

   <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">

    <h2 class="title">Lists</h2>
    <ul id="items" class="list-group">
      <li class="list-group-item">Item 1</li>
    </ul>
   </div>
  </div>
  </body>
</html>

如何在UI results.title中按<li class="list-group-item">Item 1</li>列出电影名称？
我还需要通过id选择特定的电影并将其存储在另一个json集合中。

Answer 1

在您的后加载功能中，从数据中获取结果并遍历所有项目。使用li将ul添加到.append

使用document.createElement创建一个新的li。

使用document.createTextNode为新创建的li创建文本。

和.appendChild()，将li附加到ul。

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);

在您的后加载功能中，从数据中获取结果并遍历所有项目。使用li将ul添加到ul。

这也是，但是现在遵循一个代码块：

var data = JSON.parse(this.responseText);
var option;
for (var i = 0; i < data.length; i++) 
{
 option += '<div class="list" id="' + data[i].id + '">'+ data[i].Title +'</div>';   
}
$('#items').append(option);

`
