传递变量 jquery .submit

所以本质上我是通过jquery提交表单的。有多个表单具有多个 ID 使用 question_vote_[some_value] 格式。

我使用以下选择器获取提交：

$("form[id^='question_vote_']").submit(function(event){
    vote_on_question_recent(/* I need to add the value preceeding the id in here */);
    event.preventDefault();
})

这是我的表单代码：

<?php 
if ($question_choices)
{
    echo '<form action="" method="post" enctype="multipart/form-data" value="' . $question_details['question_id'] . '" id="question_vote_' . $question_details['question_id'] .  '">';
      while($question_choice = $database->fetch_array($question_choices)) 
      {
        // do something with the $row
        echo '<input type = "radio" name = "radio_button_recent_' . $question_details['question_id'] . '" id = "radio_button_' . $question_details['question_id'] .  '_' . $question_choice['choice_id'] . '" value = "' . $question_choice['choice_id'] . '" /> <label for = "' . $question_choice['choice_text'] . '">' . $question_choice['choice_text'] . '</label><br>';
      }
    echo '<input type="submit" name="voteOnQuestion" value="Vote!" class="login_home_sub"></form>';
}
?>

然后，我的"vote_on_question_recent"函数有以下代码：

function vote_on_question_recent(question_id)
{   
    var form_name = 'vote_form';
    var choice_id = $('[name=radio_button_recent_' + question_id + ' ]:checked').val();
    if(choice_id)
    {
        $.ajax({
            type:"POST",
            url: "API/index.php",
            data: {vote_form: form_name, question_id: question_id, choice_id: choice_id},
            success: function(result){
                if(result == 'success'){
                    alert(result);
                    return false;
                }
                else
                {
                    alert('error');
                    return false;
                }
            },
            error: function (xhr, ajaxOptions, thrownError) {
                alert(xhr + ' / ' +  ajaxOptions + ' / Error:' + thrownError + ' Submitted choice:' + choice_id + ' question id:' + question_id);
                return false;
            }
        });
    }
}

所以本质上我正在寻找某种方式将"question_id"传递给我的 javascript 提交函数，或者获取提交表单的实际 ID，以便我可以解析它并以这种方式获取 ID。
