我有来自Bootstrap的这个下拉菜单。我有不同的类别,用户可以选择。当他们点击“部门”时按钮并选择一个部门,我想要的部门'按钮可以更改为用户选择的任何内容。我附上了下拉列表的HTML。
<form class="navbar-form navbar-left" action="{{ url_for('my_view.product_search') }}" method="GET">
<div class="form-group">
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<div class="input-group-btn">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Department <span class="caret"></span></button>
<ul class="dropdown-menu">
<li><a href="#">Laptops</a></li>
<li><a href="#">Cameras</a></li>
<li><a href="#">Gaming</a></li>
<li><a href="#">Networking</a></li>
<li><a href="#">Tools</a></li>
<li><a href="#">Headphones</a></li>
<li><a href="#">Speakers</a></li>
<li><a href="#">Miscellaneous</a></li>
<li><a href="#">Blu-Ray</a></li>
</ul>
</div><!-- /Dropdown Button -->
<input type="text" name="name" class="form-control" placeholder="Search Products...">
</div><!-- /input-group -->
<button type="submit" class="btn btn-default">Submit</button>
</div><!-- /.col-lg-6 -->
</div>
</form><!-- END SEARCH FUNCTION -->
修改 Here是指向下拉列表的链接
答案 0 :(得分:1)
您需要使用javascript。我在<li>
标记中的链接添加了一个click事件,在按钮中添加了一个<span>
以允许简单的jQuery选择。这里的URL与我的本地测试环境有关。
这是一个有效的例子:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>StackOverflow Testing...</title>
<link href="{{ url_for('static', filename='css/bootstrap.min.css') }}" rel="stylesheet">
</head>
<body>
<form action method="post">
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<div class="input-group-btn">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><span id="button_text">Department</span> <span class="caret"></span></button>
<ul class="dropdown-menu">
<li><a class="select_option" href="#">Laptops</a></li>
<li><a class="select_option" href="#">Cameras</a></li>
<li><a class="select_option" href="#">Gaming</a></li>
<li><a class="select_option" href="#">Networking</a></li>
<li><a class="select_option" href="#">Tools</a></li>
<li><a class="select_option" href="#">Headphones</a></li>
<li><a class="select_option" href="#">Speakers</a></li>
<li><a class="select_option" href="#">Miscellaneous</a></li>
<li><a class="select_option" href="#">Blu-Ray</a></li>
</ul>
