1、新页面user.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>
<ul class="nav nav-tabs"> <li class="nav-item"> <a class="nav-link" href="#">全部问题</a> </li> <li class="nav-item"> <a class="nav-link" href="#">全部评论</a> </li> <li class="nav-item"> <a class="nav-link disabled" href="#">个人信息</a> </li> </ul>
2、user.html继承base.html。
重写title,head,main块.
将上述<ul>放在main块中.
定义新的块user。
user.html：
{% extends ‘base.html‘ %}
{% block title %}个人中心{% endblock %}
{% block head %}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
{% endblock %}
{% block main %}
<div class="container">
<h2 style="text-shadow: 5px 5px 5px pink">Adaily</h2>
<ul class="nav nav-tabs">
<li class="nav-item">
<a class="nav-link" href="#">全部问题</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">全部评论</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">个人信息</a>
</li>
</ul>
</div>
{% block user %}{% endblock %}
{% endblock %}
3、让上次作业完成的个人中心页面，继承user.html，原个人中心就自动有了标签页导航。
4、制作个人中心的三个子页面，重写user.html中定义的user块。
全部问题html：
{% extends ‘usercenter.html‘ %}
{% block title %}个人中心{% endblock %}
{% block head %}{% endblock %}
{% block user %}
<div class="page-header">
<h3>{{ username }}><br>
<small>全部问答<span class="glyphicon glyphicon-user" aria-hidden="true"></span>
</small></h3>
<ul class="list-group"
style="padding-left: 0px; padding-right: 10px; box-shadow: rgba(0, 0, 0, 0.498039) 0px 0px 0px 0px;">
{% for foo in questions %}
<li class="list-group-item">
<span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
<a href="#">{{ foo.author.username }}</a>
<span class="badge">{{ foo.creat_time }}</span>
<p style="">{{ foo.detail }}</p>
</li>
{% endfor %}
</ul>
</div>
{% endblock %
全部评论html：
{% extends ‘usercenter.html‘ %}
{% block title %}个人中心{% endblock %}
{% block head %}{% endblock %}
{% block user %}
<div class="page-header">
<h3>{{ username }}><br>
<small>全部问答<span class="glyphicon glyphicon-user" aria-hidden="true"></span>
</small></h3>
<ul class="list-group"
style="padding-left: 0px; padding-right: 10px; box-shadow: rgba(0, 0, 0, 0.498039) 0px 0px 0px 0px;">
{% for foo in questions %}
<li class="list-group-item">
<span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
<a href="#">{{ foo.author.username }}</a>
<span class="badge">{{ foo.creat_time }}</span>
<p style="">{{ foo.detail }}</p>
</li>
{% endfor %}
</ul>
</div>
{% endblock %
全部信息html：
{% extends ‘usercenter.html‘ %}
{% block title %}个人中心{% endblock %}
{% block head %}{% endblock %}
{% block user %}
<div class="page-header">
<span class="glyphicon glyphicon-info-sign" aria-hidden="true">个人信息</span>
<ul class="nav nav-tabs">
<li class="list-group-item">用户：{{ username }}</li>
<li class="list-group-item">编号：</li>
<li class="list-group-item">昵称：</li>
</li>
</ul>
</div>
{% endblock %}
5、思考如何实现点标签页导航到达不同的个人中心子页面。
