使用ajax完成python flask前端与后台数据的交互

一、前端页面中

html文件中：
{% extends 'base.html' %}
{% block scripts %}
    {{ super() }}
{#    #}
    
    

    
    
{% endblock %}

{% block content %}
    {{ super() }}
    
jQuery Example
    
 +
        =
       ?
    
点击开始计算


{% endblock %}

flask路由函数中

@check_info.route('/_add_numbers')
def add_numbers():
    a = request.args.get('a', 0, type=int)
    b = request.args.get('b', 0, type=int)
    tt=jsonify(result=a + b)
    return tt
@check_info.route('/weather',methods=['POST','GET'])
def weather():
    list = [1, 2, 3, 4, 5, 6]

    # return jsonify(month=[x for x in list])
    return render_template('jso.html')

二、直接从flask路由函数中获取json数据然后渲染在前端页面中

{% extends 'base.html' %}
{% block scripts %}
    {{ super() }}
{#    #}
    
    

    
    
{% endblock %}

{% block content %}
    {{ super() }}
    

    {{ st }}
   

    


{% endblock %}

flask路由函数中

@check_info.route('/weather',methods=['POST','GET'])
def weather():
    list = [1, 2, 3, 4, 5, 6]
    return jsonify(month=[x for x in list])
@check_info.route('/ch')
def ch():
    return render_template('charts.html')
