我试图使一个搜索电影的应用程序,当我在输入框中输入的值,它给我所有的容器包含标题,图像和率。现在我试图给标题的API数组的值,当我点击按钮搜索电影。
我被卡住了,因为当我循环数组时,它只给我最后一个值,而当我试图追加时,它给我所有的值。

const moviesCtn = document.querySelectorAll('.jsMovieFlex');
const input = document.querySelector('#inpText');
const button = document.querySelector('#btn');

button.addEventListener('click', () => {
  const inpValue = input.value;
  moviesCtn.forEach(ctn => {
    ctn.style.display = 'flex';
  })
  searchMovie(`https://api.tvmaze.com/search/shows?q=${inpValue}`);
})

const searchMovie = async(url) => {
  const moviesImage = document.querySelectorAll('.jsMovieImage');
  const titles = document.querySelectorAll('.title-movie');
  const rates = document.querySelectorAll('h3');
  const req = await fetch(url);
  const data = await req.json();
  console.log(data);
  const arrayNames = data.map(names => names.show.name);
  console.log(arrayNames);
  for (let i = 0; i < arrayNames.length; i++) {
    const names = arrayNames[i];
    console.log(names);
    titles.forEach(title => {
      title.append(names);
    })
  }

}

问题出在你的for中,你遍历了名字并将其分配给所有标题,这意味着姓氏将出现在所有标题上:

for (let i = 0; i < arrayNames.length; i++) {
    const name = arrayNames[i];
    titles.forEach(title => {
      title.append(name); // <------- each title gets current name
    })
  }

但是你只想把它分配给索引i处的标题:

for (let i = 0; i < arrayNames.length; i++) {
    const name = arrayNames[i];
    titles[i].append(name)
  }

我的猜测是你对命名感到困惑(我确实如此),因为它是非常明显的。使用更多的声明性变量名可能会有所帮助,特别是那些独特的变量名(即避免使用彼此相邻的同义词,如“title”和“name”):

for (let i = 0; i < movieNames.length; i++) {
    const movieName = movieNames[i];
    titleTags[i].append(movieName)
  }
