python——由Flask渲染的引导边栏不会折叠
相关标签： # node.js
我正在创建一个Flask Web应用程序，我想使用Bootstrap 5.0侧边栏，所以我转到Bootstrap示例页面，下载了适合我需要的示例。简单的HTML/CSS/JS文件工作正常。如果单击第一级选项左侧的按钮，第二级将自动关闭/展开。但是，当我使用render_template Flask函数调用同一个HTML文件时，colapse/expand不起作用。
这是原始的HTML文件（由于这里的大小限制，我删除了一个符号svg会话）

</html>下面是我用来创建应用程序的python文件。
这个初始化.py以创建蓝图。
from flask import Blueprint
main = Blueprint('main',__name__)
from . import views
这个初始化.py在应用程序文件夹中
from flask import Flask
from flask_bootstrap import Bootstrap
from flask_moment import Moment
from flask_googlecharts import GoogleCharts
bootstrap = Bootstrap()
moment = Moment()
def create_app():
app = Flask(__name__)
app.debug=True
with app.app_context():
bootstrap.init_app(app)
moment.init_app(app)
from .main import main as main_blueprint
app.register_blueprint(main_blueprint)
return app
和view.py文件
from flask import Flask,session,request,render_template,jsonify,url_for,redirect,flash
from flask_bootstrap import Bootstrap
from . import main
@main.route("/")
def home():
return render_template('index.html')
我没有从boostrap更改css/js中的任何内容。有人见过这样的事吗？
