asp.net-mvc-3 – 如何通过ajax上传文件

HTML和jQuery函数

<div id="Upload">
    <input type="file" accept="application/x-shockwave-flash" id="virtualtourfile" enctype="multipart/form-data"/>
    <input type="button" value="Upload" id="btnUpload"/>
</div>

$('#btnUpload').click(function () {
            $.ajax({
                url: "uploadvideo",type:'POST',data: $("#virtualtourfile:file"),success: function (data) {

                }
            });
        });

调节器

public ActionResult UploadVideo(HttpPostedFileBase file)
        {
            return Json("",JsonRequestBehavior.AllowGet);
        }
