根据数据库中的单选按钮值显示div

<div id="div1">Div 1</div>
<div id="div2">Div 2</div>
<div id="div3">Div 3</div>

import mysql.connector

# 连接到数据库
cnx = mysql.connector.connect(user='username', password='password', host='localhost', database='database_name')

# 创建游标对象
cursor = cnx.cursor()

# 查询单选按钮的值
query = "SELECT radio_button_value FROM table_name WHERE id = 1"
cursor.execute(query)

# 获取查询结果
result = cursor.fetchone()

# 根据单选按钮的值确定要显示的div
if result[0] == 'div1':
    div_to_show = 'div1'
elif result[0] == 'div2':
    div_to_show = 'div2'
elif result[0] == 'div3':
    div_to_show = 'div3'

# 关闭游标和数据库连接
cursor.close()
cnx.close()

<script>
    var divToShow = "{{ div_to_show }}";
    document.getElementById(divToShow).style.display = "block";
</script>
