How can I make the program reload JSON data when refreshing the browser?

Question

The JSON file is a list that contains a dictionary.
The data presented to the user is randomly extracted from the list.
Now, I need to get it every time the user refreshes the browser.
What should I do?

This is the example code:

def get_ana(file):
    if not os.path.exists(file):
        ana_messages = file_not_found_error(file)
        ana_status = False
        return ana_status, ana_messages
    else:
        # asyncio.run(load_ana(file))
        with open(file, 'r') as f:
            ana_messages = json.load(f)
        number = random.randint(0, len(ana_messages) - 1)
        print(number)
        ana_messages = ana_messages[number]
        ana_status = True
        return ana_status, ana_messages

ana = get_ana("data/a.json")

if not ana[0]:
    id = ana[1][0]["id"]
    msg = ana[1][0]["msg"]
    author = ana[1][0]["author"]
    time = ana[1][0]["time"]
else:
    id = ana[1]["id"]
    msg = ana[1]["msg"]
    author = ana[1]["author"]
    time = ana[1]["time"]

with ui.card().classes("absolute-center"):
    with ui.row():
        ui.badge("id")
        ui.label(id)
    with ui.row():
        ui.badge("语录")
        ui.label(msg)
    with ui.row():
        ui.badge("作者")
        ui.label(author)
    with ui.row():
        ui.badge("时间")
        ui.label(time)

Hi @SHDocter,

You can move your code into a page function, which is called every time a page is requested:

@ui.page('/')
def main_page():
    ...
