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