Javascript 使用python，我如何判断一个html复选框是否被隐藏，以及它是否被S选中

在一个HTML表单中，我有一个复选框，根据用户之前的 Select ，哪个类是"隐藏"的或不是隐藏的.

这是我的HTML JavaScript代码，它创建了复选框

const cityBusesLabel = document.createElement('label');
cityBusesLabel.textContent = `Use of city buses`;
const cityBusesInput = document.createElement('input');
cityBusesInput.type = 'checkbox';
cityBusesInput.name = `cityBuses ${venueNumber}-${originCounter}`;
cityBusesInput.id = `cityBusesInput ${venueNumber}-${originCounter}`;
cityBusesInput.classList.add('hidden');
cityBusesLabel.id = `cityBusesLabel ${venueNumber}-${originCounter}`;
cityBusesLabel.classList.add('hidden');
cityBusesLabel.appendChild(cityBusesInput);

下面是显示/隐藏它的HTMLjavascript代码:

document.getElementById('venue_location_' + venueNumber).addEventListener('input', function() { 
    const select_value = document.getElementById('venue_location_' + venueNumber).value;
    if (select_value === 'suburban') {
        document.getElementById('cityBusesInput ' + venueNumber + '-' + originCounter).classList.remove('hidden');
        document.getElementById('cityBusesLabel ' + venueNumber + '-' + originCounter).classList.remove('hidden');
    } else {
        document.getElementById('cityBusesInput ' + venueNumber + '-' + originCounter).classList.add('hidden');
        document.getElementById('cityBusesLabel ' + venueNumber + '-' + originCounter).classList.add('hidden');
    }
});

现在，在使用Flask.py的app.py python代码中，我首先try 判断复选框是否隐藏，其次判断是否选中.

我试着写道:

cityBuses_checkbox = request.form.get(f'cityBuses {i}-{origin_counter}')
if cityBuses_checkbox :
    if cityBuses_checkbox == 'on' :
         city_buses.append(1)
    else :
         city_buses.append(0)

但它没有给我想要的输出.这两项判断是这样做的吗？
