如何在Ajax Json中向Flask提交多个复选框值？

<input type="checkbox" name="option1" value="value1"> Option 1
<input type="checkbox" name="option2" value="value2"> Option 2
<input type="checkbox" name="option3" value="value3"> Option 3

$('#submitBtn').click(function() {
    var formData = $('form').serializeArray();
    var jsonData = {};
    $.each(formData, function(index, field) {
        if (jsonData[field.name]) {
            jsonData[field.name].push(field.value);
        } else {
            jsonData[field.name] = [field.value];
        }
    });
    // 发送Ajax请求
    $.ajax({
        url: '/submit',
        type: 'POST',
        data: JSON.stringify(jsonData),
        contentType: 'application/json',
        success: function(response) {
            // 处理响应
        }
    });
});

from flask import Flask, request

app = Flask(__name__)

@app.route('/submit', methods=['POST'])
def submit():
    data = request.get_json()
    option1_values = data.get('option1', [])
    option2_values = data.get('option2', [])
    option3_values = data.get('option3', [])
    # 处理复选框值
    # ...

if __name__ == '__main__':
    app.run()
