当用户单击单选按钮时，我正在尝试更新MySQL数据库。我计划使用jQuery/Ajax来实现这一点。我在这个网站和其他网站上查看了我做错了什么，但我找不到答案。
第一页代码：
<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>

使用firebug，当点击单选按钮时，我得到以下错误：
ReferenceError:UpdateRecord未定义[Break On This Error]
UpdateRecord（448，24，"团队"，2）；
如有任何帮助，我们将不胜感激。谢谢
将UpdateRecord移动到DOM之外。然后将处理程序连接到文档就绪内部的单选按钮。
var UpdateRecord = function(gid, user, pick, wk) {}
$(function(){
$('input[type=radio]').on( "change" , function(){
UpdateRecord(....)
});
});
如果没有HTML，我们将无法提供太多帮助，因为我们不知道gid, user, pick, wk是在哪里定义的。你需要在类似的HTML中输出它们
<input class='ajaxSubmit' type="radio" gid="23892" user="myUser" pick="myPick" wk="myWk"/>
然后在点击时执行提交ajax：
$(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");
}
}
});
});
});
