• 加载静态文件,父模板的继承和扩展


    1. 用url_for加载静态文件
      1. <script src="{{ url_for('static',filename='js/login.js') }}"></script>
      2. flask 从static文件夹开始寻找
      3. 可用于加载css, js, image文件
    2. 继承和扩展
      1. 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
      2. 子模板继承父模板
        1.   {% extends 'base.html’ %}
      3. 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 %}
      4. 子模板中写代码实现自己的需求。block
        1.   {% block title %}登录{% endblock %}
    3. 首页、登录页、注册页都按上述步骤改写。
