Flask实战第47天：首页导航条首先和代码抽离

新建一个前台页面的父模板front_base.html

导航条是总boostrap v3中文站拷贝过来的，然后根据自己的需求做一些修改

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="csrf-token" content="{{ csrf_token() }}">
    <title>{% block title %}{% endblock %}</title>
    <script src="http://cdn.bootcss.com/jquery/3.1.1/jquery.min.js"></script>
    <link href="http://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
    <script src="http://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
    <script src="{{ url_for('static', filename='common/js/bbsajax.js') }}"></script>
    <link href="{{ url_for('static', filename='common/sweetalert/sweetalert.css') }}" rel="stylesheet">
    <script src="{{ url_for('static', filename='common/sweetalert/sweetalert.min.js') }}"></script>
    <script src="{{ url_for('static', filename='common/sweetalert/xtalert.js') }}"></script>
    {% block head %}{% endblock %}
</head>
<body>

    <nav class="navbar navbar-default">
      <div class="container-fluid">
        <div class="navbar-header">
          <a class="navbar-brand" href="#">何波安BBS论坛</a>
        </div>

        <!-- Collect the nav links, forms, and other content for toggling -->
        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
          <ul class="nav navbar-nav">
            <li><a href="#">首页</a></li>
          </ul>
          <form class="navbar-form navbar-left">
            <div class="form-group">
              <input type="text" class="form-control" placeholder="请输入关键字">
            </div>
            <button type="submit" class="btn btn-default">搜索</button>
          </form>
          <ul class="nav navbar-nav navbar-right">
            <li><a href="#">登录</a></li>
            <li><a href="#">注册</a></li>
          </ul>
        </div>
      </div>
    </nav>
    
    {% block body %}{% endblock %}

</body>
</html>

front_base.html

新建首页front_index.html继承front_base.html

{% extends 'front/front_base.html' %}

{% block title %}首页-BBS论坛{% endblock %}

{% block head %}{% endblock %}

{% block body %}这是首页内容{% endblock %}

修改视图，编辑front.views.py

@bp.route('/')
def index():
    return render_template('front/front_index.html')
