如何在 Bootstrap 5 模式中指定 API 对象？

Question

我不能直截了当，已经有一段时间了。基本上，我在这个电影应用程序上，需要一个模态。到目前为止，我必须指出要单独放映每部电影，展示它们的海报、标题和配乐。

现在，我们的想法是按下标题，模态框将弹出描述 ${overview}。好的，它有效，但是！模式只显示第一个对象的描述，无论我按哪个电影的标题。

删除模态框并添加 <div>${overview}</div> 后，它可以正常工作，正确显示每部电影的描述，但一旦我将其放入模态框，它将无法正常工作。

我试图通过点击该按钮来玩弄，到处搜索，但找不到解决方案。任何帮助或指导都会很棒，谢谢！

是的，你基本上错过了两件事：

1. 模式内容的文本颜色
2. 每个按钮和模式的唯一 ID

这是一个可行的解决方案： P.S：您也可以在 JSfiddle here 上查看。

Answer 2

您需要更改data-bs-target 来绑定不同的按钮和模式。

  movies.forEach((movie) => {
    const {poster_path, title, vote_average, overview, uid} = movie; // Pulling necessary names from API
    console.log(overview)

    const movieBox = document.createElement("div"); //creating a div for individual movie elements
    movieBox.classList.add("movie"); // creating a class for it

    movieBox.innerHTML = `
      <div class="movie-image"><img src="${IMGPath + poster_path}" alt="${title}" /></div>
      <div class="movie-info">
        <button type="button" class="btn" data-bs-toggle="modal" data-bs-target="#${uid}">
          ${title}
        </button>
        <span class="${classByRating(vote_average)}">${vote_average}</span>
        
        <div class="modal fade" id="${uid}" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
          <div class="modal-dialog modal-dialog-centered modal-dialog-scrollable">
            <div class="modal-content">
              <div class="modal-header">
                <h5 class="modal-title" id="exampleModalLabel">${title}</h5>
                <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
              </div>
              <div class="modal-body">
                ${overview}
              </div>
              <div class="modal-footer">
                <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
              </div>
            </div>
          </div>
        </div>
      </div>
    `; // creating markup for every movie element and pulling information from API

    

    mainSection.appendChild(movieBox); // sending back to HTML file
  });
