Question

我正在为学校做一个项目，这是一个显示所有电影信息的网站。我正在使用 api 电影数据库，html css 和 javascript

现在我正在尝试让按钮带我去看某种类型的电影

这是我在 html

上的代码

<div class="wrapper-structure-esqueleto">

            <img class="logo" src="img/logo.png" alt="logo">

            <div class="first-section-hiperlinks">

                <h3>DISCOVER</h3>
                
                <a class="border-initial">
                    <p> aaa </p>
                </a>
                <a class="border">
                    <p> aaa </p>
                </a>
                <a class="border">
                    <p> aaa </p>
                </a>

            </div>
            <div class="second-section-hiperlinks">

                <h3>GENRES</h3>
            
                    <a href="#" class="border" id="doc-genre">
                        <p> genre-name </p>
                    </a>

            </div>

            <div class="footer">
                <div class="credits">
                    <p>Made by <strong>Francisco Lemos</strong></p>
                </div>
                <img src="img/poweredby.png">
            </div>

        </div>

        <!-- doc -->

        <div class="wrapper-structure">

            <img class="logo" src="img/logo.png" alt="logo">

            <div class="first-section-hiperlinks">

                <h3>DISCOVER</h3>
                
                <a class="border-initial">
                    <p> aaa </p>
                </a>
                <a class="border">
                    <p> aaa </p>
                </a>
                <a class="border">
                    <p> aaa </p>
                </a>

            </div>
            <div class="second-section-hiperlinks">

                <h3>GENRES</h3>
            
                <div class="wrapper" id="find-genres">
        
                </div>

            </div>

            <div class="footer">
                <div class="credits">
                    <p>Made by <strong>Francisco Lemos</strong></p>
                </div>
                <img src="img/poweredby.png">
            </div>

        </div>

这是我在 js 上的代码

function getFindGenres(){

  document.querySelector('.wrapper').innerHTML = "";

  axios( {
      method: 'get',
      url: 'https://api.themoviedb.org/3/discover/movie?api_key=(API-KEY)&page=1&with_genres=28'
    })
    .then(function (response) {
      response.data.with_genres.forEach(with_genres => {
        let htmlFindGenres = document.querySelector('.wrapper').outerHTML;
        htmlFindGenres = htmlFindGenres.replace('#find-genres',genre_ids);
        var d4 = document.querySelector('.wrapper');
        d4.insertAdjacentHTML('beforeend', htmlFindGenres);
      })
    })
}

这行给我错误

 response.data.with_genres.forEach(with_genres => {

我不知道该放什么，有人可以帮我吗？

Answer 1

Payload没有属性with_genres，是吗？

所以这应该可以，但还没有测试，所以请告诉我：

function getFindGenres(){

  document.querySelector('.wrapper').innerHTML = "";

  axios( {
      method: 'get',
      url: 'https://api.themoviedb.org/3/discover/movie?api_key=(API-KEY)&page=1&with_genres=28'
    })
    .then(function (response) {
      response.data.results.forEach(result => {
        let htmlFindGenres = document.querySelector('.wrapper').outerHTML;
        htmlFindGenres = htmlFindGenres.replace('#find-genres',result.genre_ids);
        var d4 = document.querySelector('.wrapper');
        d4.insertAdjacentHTML('beforeend', htmlFindGenres);
      })
    }) }
