ajax 文件上传

网上找的例子，自己写了，action里始终得不到文件,输出的是0 file uploaded. 需要改哪里
</script>
<script type="text/javascript" src="/sdzw/sdzw/pages/js/jquery-1.3.2.js"> </script>
<script type="text/javascript" src="/sdzw/sdzw/pages/js/ajaxfileupload.js"> </script>
<script type="text/javascript" src="/sdzw/sdzw/pages/js/jquery.blockUI.js"> </script>
<script type="text/javascript">

function onClick_button4() {
return ajaxupload();
}

function ajaxupload()
{
$.blockUI.defaults.fadeOut=1500;
// //1.ajax开始上传前锁定界面
//$.blockUI({message:"<img src='imgs/loading.gif'/>文件上传中..."});
$("#start").ajaxStart(
function(){
$.blockUI({message:"<img src='/sdzw/sdzw/pages/js/loading.gif'/>文件上传中..."});
}
);
//2.上传
$.ajaxFileUpload
(
{
url:'jquerytest.do',
secureuri:false,
fileElementId:'file3',
dataType: 'json',

success: function (data, status)
{
if(typeof(data.error) != 'undefined')
{
if(data.error != '')
{
alert(data.error);alert('data.error');
}else
{
alert(data.msg);alert('data.msg');
}
}
},
// success: function (data, status)
// {
// //如果文件上传成功
// $.blockUI({message:data.msg});
// },
error: function (data, status, e)
{
// $.blockUI({message:data.error});
alert(e);alert('e');
}
}
)

//3 .ajax完成解锁
$("#start").ajaxComplete(function(){
$.unblockUI();
});

}
