html - 在卡片中添加折叠页脚（引导程序）

问题描述

我做了三个块——在引导程序中使用 CARD 类。效果很好。现在我想在允许“显示/隐藏详细信息”的卡片上添加一个页脚（或只是一个 div）。

我尝试了 10 种不同的方法，但由于某种原因，卡片总是“断裂”。我有适用于卡片但没有崩溃的代码

目标是让最后 3 行折叠，同时“显示付款计划”更改为“隐藏付款计划”。

谁知道怎么去那里？在不破坏卡片的情况下将 div 类放在哪里？

解释

我添加了

data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample"

对你span来说，它的工作原理就像collapsable toggler并添加了rootdiv

class="collapse show" id="collapseExample"

到你的三个项目，所以只有一个 div 可以折叠。

document.querySelectorAll('.change_text').forEach(cur => {
  cur.addEventListener('click', e => {
    const target = e.target;
    if (target.textContent === 'Show payment schedule') {
      target.textContent = 'Hide payment schedule';
    } else {
      target.textContent = 'Show payment schedule';
    }
  })
});
