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

from flask import Flask,render_template

app = Flask(__name__)

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

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

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

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