篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了加载静态文件,父模板的继承和扩展相关的知识，希望对你有一定的参考价值。

  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。 
    from flask import Flask,render_template

app = Flask(__name__)



@app.route(‘/login‘)
def login():
    return render_template(‘login.html‘)

@app.route(‘/regist‘)
def register():
    return render_template(‘regist.html‘)

@app.route(‘/base‘)
def base():
    return render_template(‘base.html‘)

@app.route(‘/‘)
def index():
    return render_template(‘index.html‘)


if __name__ == ‘__main__‘:
    app.run(debug=True)
