如何处理嵌套数据父级

Question

我想使用数据父级创建一个具有3个级别的菜单，就像这样关闭：

Menu1
---SubMenu1
------Sub_SubMenu1
------Sub_SubMenu2
---SubMenu2
Menu2
---SubMenu22
------Sub_SubMenu21
------Sub_SubMenu22
---SubMenu22

所以我有以下示例代码（不具有完整菜单）：

    <div id="Menu1">
       <button data-toggle="collapse" data-target="#div1">
                    Menu1
        </button>
        <div id="div1" data-parent="Menu1">
          <div id="SubMenu1">
       <button data-toggle="collapse" data-target="#div1">
                    SubMenu1
        </button>
<div id="submenu1"></div>
       <button data-toggle="collapse" data-target="#submenu2">
                    SubMenu2
        </button>
<div id="submenu2"></div>
          </div>
        </div>
    </div>

我的问题是当我打开任何SubSubMenu并打开菜单后，SubSubMenu没有关闭。

Answer 1

HOST, PORT ='localhost', 50007

def get_data():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((HOST, PORT))

    print("connected to Server")

    data = s.recv(6)

    print(data)
    data = data.partition(b'\x00',)[0]
    data = data.decode('utf-8')
    print(int(data))
    s.close()



if __name__ == '__main__':
    get_data()

Answer 2

如果要在“代码段”中进行测试，则其外观将与智能手机上的外观完全相同，但是外观会完全不同on the desktop
