- 新页面userbase.html,用<ul ><li role="presentation"> 实现标签页导航。
<ul class="nav nav-tabs">
<li role="presentation"><a href="#">Home</a></li>
<li role="presentation"><a href="#">Profile</a></li>
<li role="presentation"><a href="#">Messages</a></li>
</ul>
{% extends ‘base.html‘ %} {% block title %} 个人中心 {% endblock %} {% block head %} <style> .nav_ul li{ list-style: none; float: left; margin: 10px; } </style> {% endblock %} {% block main %} <ul class="nav_ul"> <li role="presentation"><a href={{ url_for(‘user1‘,user_id = user.id) }}>全部问答</a> </li> <li role="presentation"><a href="user2">全部评论</a> </li> <li role="presentation"><a href="user3">个人资料</a> </li> {% block user %}{% endblock %} </ul> {% endblock %}
- 让userbase.html继承base.html。
重写title,head,main块.
将上述<ul>的样式放在head块，<ul>放在main块中.
定义新的块user。 - 让上次作业完成的个人中心页面，继承userbase.html，原个人中心就自动有了标签页导航。
{% extends ‘userbase.html‘ %} {% block user %} <div class="page-header"> <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>{{ username }}<br><small>全部问答<span class="badge"></span></small></h3> <ul class="list-group" style="align-items: center"> {% for foo in questions %} <li class="list-group-item"> <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span> <a href="{{ url_for(‘usercenter‘,user_id=foo.author_id)}}">{{ foo.author.username }}</a> <span class="badge">{{ foo.creat_time }}</span> <p style="text-indent: 18px">{{ foo.detail }}</p> </li> {% endfor %} </ul> </div> {% endblock %}
- 制作个人中心的三个子页面，重写userbase.html中定义的user块，分别用于显示问答、评论、个人信息。
{% extends ‘userbase.html‘ %} {% block user %} <div class="page-header"> <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>{{ user }}<br><small>个人信息<span class="badge"></span></small></h3> <ul class="list-group" style="align-items: center"> <a href="{{ url_for(‘usercenter‘,user_id=foo.author_id)}}">{{ foo.author.username }}</a> <li class="list-group-item">用户：{{ username }}</li> <li class="list-group-item">编号：{{ userid }}</li> <li class="list-group-item">昵称：{{ questions }}</li> <li class="list-group-item">文章篇数：{{ comments }}</li> </ul> </div> {% endblock %}
- 思考 如何实现点标签页导航到达不同的个人中心子页面
