<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="Generator" content="EditPlus®"> <meta name="Author" content=""> <meta name="Keywords" content=""> <meta name="Description" content=""> <title> 应用</title> <link href="bootstrap.min.css" rel="stylesheet" style="test/css"> <script src="jquery-2.2.3.min.js"></script> <script src="bootstrap.min.js"></script> </head> <body> <div class="dropdown" id="myDropdown"> <button id="dLabel" class="btn btn-primary" type="button" data-toggle="dropdown"> 下拉菜单 <span class="caret"></span> </button> <ul class="dropdown-menu"role="menu"> <li><a href="#">我的</a></li> <li><a href="#">我的</a></li> <li><a href="#">我的</a></li> </ul> </div> </body> </html>
如果下拉菜单展示时，要弹出信息，加入代码：
<script>
$("#myDropdown").on("shown.bs.dropdown",function(e){
alert("Heelo")
})
</script>
