加载静态文件,父模板的继承和扩展

夜绵绵用url_for加载静态文件

flask 从static文件夹开始寻找

可用于加载css, js, image文件

 <link rel="stylesheet" href="{{ url_for('static',filename='css/base.css') }}">
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
    <script src="{{ url_for('static',filename='js/base.js') }}"></script>

    <nav class="navbar navbar-default" role="navigation">
        <div class="container-fluid">
            <div class="navbar-header">
                <a class="navbar-brand" href="#">广州商学院</a>

            </div>
            <form class="navbar-form navbar-left" role="search">
                <div class="form-group"><input type="text" class="form-control" placeholder="输入您感兴趣的"></div>
                <button type="submit" class="btn btn-default" style="width: 70px">查询</button>
                </form>
            <ul class="nav navbar-nav navbar-right"id="myBody">
                <li> <img src="{{ url_for('static',filename='css/timg.jpg') }}" alt="" width="40px"></li>

2.继承和扩展

把一些公共的代码放在父模板中，避免每个模板写同样的内容。base.html
1. 子模板继承父模板
  1. {% extends 'base.html’ %}
2. 父模板提前定义好子模板可以实现一些自己需求的位置及名称。block
  1. <title>{% block title %}{% endblock %}-MIS问答平台</title>
  2. {% block head %}{% endblock %}
  3. {% block main %}{% endblock %}
3. 子模板中写代码实现自己的需求。block
  1. {% block title %}登录{% endblock %}
首页、登录页、注册页都按上述步骤改写。

父模版html
