bootstrap dropdown下拉框如何从数据库取值然后动态赋值 ，目前只是单纯赋值

<div class="container-fluid">
<button type="button" style="color:#0089d2;adding-left:0px;text-align:left;" class="btn dropdown-toggle" id="dropdownMenu" data-toggle="dropdown">
阳台新风机
<!-- <span class="caret"></span> -->
<img src="<%=path %>/image/jt.png">
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
<li role="presentation">
<a role="menuitem" tabindex="-1" href="#">阳台新风机</a>
</li>
<li role="presentation">
<a role="menuitem" tabindex="-1" href="#">办公室新风机</a>
</li>
</ul>
</div>

Answer 1

从后台异步取数据，然后，按照这个格式
<li role="presentation">
<a role="menuitem" tabindex="-1" href="#">阳台新风机</a>
</li>
<li role="presentation">
<a role="menuitem" tabindex="-1" href="#">办公室新风机</a>
</li>
拼接上去就好
