加载静态文件,父模板的继承和扩展
- 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。
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title> {% block title %} {% endblock %} 首页</title> <link rel="stylesheet" type="text/css" href="{{ url_for('static', filename='css/base.css') }}"> <script src="{{ url_for('static',filename='js/base.js') }}"></script> {% block head %} {% endblock %} a </head> <body id="myBody"> <nav> <img id="myOnOff" onclick="mySwitch()" src="{{ url_for('static',filename='image/pic_bulboff.gif') }}" width="30px"> <a href="{{ url_for('base') }}">首页</a> <a href="{{ url_for('regist') }}">注册</a> <a href="{{ url_for("login")}}" >登录</a> </nav> {% block main %} {% endblock %} <div class="area"></div> </div> </body> </html>
