然而，当我实际呈现页面时，input-group-append部分似乎不起作用。

但是，这显然不像示例here。
不知道我应该做什么不同的这里，这是一个错误的引导4.0测试版？
快速补充说明一下，如果这是相关的，我使用的是Django 2.0。

我今天刚遇到这个。我仔细检查了我的风格和脚本，一切都很好。我没有使用append和preped，而是使用了input-group-addon和input-group-btn。

没有窃听器。
你加入了很多不必要的东西。jQuery造成了很多中断。在添加脚本时要小心，因为可能会发生冲突。请参考我的代码

Bootstrap 4已退出alpha版本（在回答此问题时为4.1），现在应该可以执行以下操作：

<div class="form-group">
    <label for="price">Price</label>
    <div class="input-group-btn">
      <div class="input-group-prepend">
        <span class="input-group-text">$</span>
        <input id="price" type="number" class="form-control" />
        <span class="input-group-text">.00</span>
      </div>
    </div> 
  </div>

因此，请将input-group-btn类与input-group-prepend（或input-group-prepend）和input-group-text沿着使用。
检查输入组here的4.1版文档。

万一别人提出同样的问题，我就这样做了

<div class="input-group mb-3">
  <input type="password" class="form-control" placeholder="Insert password...">
  <button class="btn btn-secondary" id="btn-show-psw" type="button">show</button>
</div>

只要避免使用input-group-append或其他任何东西。只在组本身中声明input-group。
无论如何，我没有看到这个提到这种方式在官方文件在here

对于 Bootstrap 5，根据此链接From bootsrap documents
这样使用

<div class="input-group mb-3">
  <span class="input-group-text">$</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  <span class="input-group-text">.00</span>
</div>

或完整示例：

<!doctype html>
<html lang="en">

<head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <!-- Bootstrap CSS -->

    <title>Hello, world!</title>
</head>

<body>
    <div class="input-group mb-3"> <span class="input-group-text">$</span>
        <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)"> <span class="input-group-text">.00</span> </div>
