在jQuery中提交多个表单不起作用

var formData = $('#form1, #form2, #form3').serialize();
$.ajax({
    url: 'your_server_url',
    type: 'POST',
    data: formData,
    success: function(response) {
        // 处理成功响应
    },
    error: function(xhr, status, error) {
        // 处理错误响应
    }
});

var formData = new FormData();
formData.append('form1', $('#form1')[0]);
formData.append('form2', $('#form2')[0]);
formData.append('form3', $('#form3')[0]);
$.ajax({
    url: 'your_server_url',
    type: 'POST',
    data: formData,
    processData: false,
    contentType: false,
    success: function(response) {
        // 处理成功响应
    },
    error: function(xhr, status, error) {
        // 处理错误响应
    }
});
