jQuery/Ajax未定义PHP MySQL

我试图在用户单击单选按钮时更新MySQL数据库。我计划使用jQuery/Ajax来实现这一点。我已经在这个网站和其他网站上看到了我做错了什么，但我找不到答案

第一页上的代码：

<script type="text/javascript" src="http://www.njacfootball.com/styles/autofill/jquery.js"></script>
<script type="text/javascript">
  $(document).ready(UpdateRecord(gid, user, pick, wk) {
    jQuery.ajax({
      type: "POST",
      url: "savePick.php",
      data: {
        gid: gid
        usr: user
        pk: pick
        wk: wk
      },
      cache: false,
      success: function(response)
      {
        alert("Pick successfully updated/saved");
      }
    }
  });
</script>

$（文档）.ready（更新记录（gid、用户、拾取、工作）{
jQuery.ajax({
类型：“POST”，
url:“savePick.php”，
数据：{
吉德：吉德
usr：用户
主键：选择
工作：工作
},
cache:false，
成功：功能（响应）
{
警报（“拾取成功更新/保存”）；
}
}
});

将UpdateRecord移出DOM ready。然后将处理程序附加到document ready内的单选按钮

var UpdateRecord = function(gid, user, pick, wk) {}

$(function(){
    $('input[type=radio]').on( "change" , function(){
        UpdateRecord(....)
    });
});

如果没有HTML，我们将帮不上什么忙，因为我们不知道在哪里定义了
gid、user、pick、wk


然后在单击时执行提交ajax操作：

$(document).ready(function(){
    $('.ajaxSubmit').on('click',function(){
        var gid = $(this).attr('gid');
        var user = $(this).attr('user');
        var pick = $(this).attr('pick');
        var wk = $(this).attr('wk');
        $.ajax({
            type: "POST",
            url: "savePick.php",
            data: {
                gid: gid
                usr: user
                pk: pick
                wk: wk
            },
            cache: false,
            success: function(response)
            {
                alert("Pick successfully updated/saved");
            }
        }
    });
    });
    });

我只是对html进行了更新，以显示我是如何提取数据并试图保存数据的。
$(document).ready(function(){
    $('.ajaxSubmit').on('click',function(){
        var gid = $(this).attr('gid');
        var user = $(this).attr('user');
        var pick = $(this).attr('pick');
        var wk = $(this).attr('wk');
        $.ajax({
            type: "POST",
            url: "savePick.php",
            data: {
                gid: gid
                usr: user
                pk: pick
                wk: wk
            },
            cache: false,
            success: function(response)
            {
                alert("Pick successfully updated/saved");
            }
        }
    });
    });
    });
