我的元素要求是在单击按钮时显示警报或对话框，在该警报上显示具有某些值的下拉列表，选择下拉列表值并使用 HTML 将其保存在数组列表中。 我试过this但它不起作用。 警报对话框应如下图所示。

最佳答案
试试这个代码...
<a data-target="#myModal" role="button" class="btn" data-toggle="modal">Launch demo modal</a>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Modal header</h3>
</div>
<div class="modal-body">
<select>
<option>test</option>
<option>test</option>
<option>test</option>
<option>test</option>
<option>test</option>
</select>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
<button class="btn btn-primary">Save changes</button>
</div>
