作业21-加载静态文件,父模板的继承和扩展
  • 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
  • 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 %}
  • 首页、登录页、注册页都按上述步骤改写。
