动态创建的boostrap 4卡显示为一列，而不是常规布局（行）

Question

这是js：

const url = 'https://jsonplaceholder.typicode.com/todos?_limit=3';

async function getDataFromCinemasAPI() {
    const response = await fetch(url);
    const data = await response.json();

    let cardContentForFilling = '<div class="container"><div class="d-flex flex-row"><div class="d-flex flex-col-md-4"><div class="card mb-4 box-shadow"><div class="card-body"><p class="card-text"> </p></div></div></div></div></div>';

    for (let i = 0; i < data.length; i++) {
        $('.album.py-5').append(cardContentForFilling);
        let cards = $('.card-text');
        cards.eq(i).html((data[i]["title"]));
    } 
}

getDataFromCinemasAPI();

这是html：

<div class="album py-5">

</div>

已经尝试使用flex列/行，但是什么也没有，它们保留为列而不是行

here's the jsfiddle

您每次都附加.container。您必须在上面。这样的事情可能会起作用：

const url = 'https://jsonplaceholder.typicode.com/todos?_limit=3';

async function getDataFromCinemasAPI() {
  const response = await fetch(url);
  const data = await response.json();

  let cardContentForFilling = '<div class="d-flex flex-col-md-4"><div class="card mb-4 box-shadow"><div class="card-body"><p class="card-text"> </p></div></div></div>';

  for (let i = 0; i < data.length; i++) {
    $('.append-here').append(cardContentForFilling);
    let cards = $('.card-text');
    cards.eq(i).html((data[i]["title"]));
  }
}

getDataFromCinemasAPI();
