JQUERY FORM AjaxSubmit异步上传文件问题

[fox123871]

异步上传文件，使用了jquery.form ajaxSubmit，提交后，后台接受不到请求

<script type="text/javascript">

$(document).ready(function () {
$("#Button1").click(function () {
if ($("#fileUp").val() =="")
{
window.alert("It is not Empty！");
return false;
}
$("#form1").ajaxSubmit({
type: "post",
url: "Handler1.ashx",
dataType: "text",
data: { "filename": $("#Text1").val() },
success: function (data) {
window.alert(data);
},
error: function () {
}
});
});
});
</script>
<form id="form1" >
<div>
内容：<input type="text" id="Text1" /><br />
文件：<input type="file" name="fileUp" id="fileUp" />
<input id="Button1" type="button" value="上传" />
</div>
</form>


后台代码：
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
int count = context.Request.Files.Count;
string name = context.Request["filename"];
HttpPostedFile hf = context.Request.Files["fileUp"];
string fileName = DateTime.Now.ToString("yyyMMddHHmmss") + Path.GetExtension(hf.FileName);
string url = context.Server.MapPath("~/Files/");
hf.SaveAs(url+fileName);
context.Response.Write("{\"status\":\"1\"}");
}

[娃都会打酱油了]

文件本来就不能通过ajax上传，只能通过form data的方式submit

只能submit吧
