Question

我在网页上添加了以下下拉Bootstrap按钮：

<!-- Example single danger button -->
<div class="btn-group">
  <button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Action
  </button>
  <div class="dropdown-menu">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
    <a class="dropdown-item" href="#">Something else here</a>
    <div class="dropdown-divider"></div>
    <a class="dropdown-item" href="#">Separated link</a>
  </div>
</div>

我想用以下图标替换文本Action：

<i class="fas fa-language"></i>

我一直在尝试下面的代码，但是它不起作用：

<div class="btn-group">
                <button id="translate"  type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                    <i class="fas fa-language"></i>
                </button>
                <div class="dropdown-menu">
                    <a class="dropdown-item" href="#">Action</a>
                    <a class="dropdown-item" href="#">Another action</a>
                    <a class="dropdown-item" href="#">Something else here</a>
                    <div class="dropdown-divider"></div>
                    <a class="dropdown-item" href="#">Separated link</a>
                </div>
            </div>
