问题描述
Helo朋友，
我如何使用asp.net mvc3将Ajax或jquery的图像文件从视图传输到控制器.
我的查看文件看起来像
Helo freinds,
How can i transfer image file using ajax or jquery from view to controller using asp.net mvc3.
My view file looks like
<script type="text/javascript">
$(document).ready(function () {
$("#photos").kendoUpload();
$("#save").click(function (event) {
alert("started");
url = 'Home/Details'
var data = $('#photos').load(url)
$.ajax({
type: "POST",
url: '/Home/Details',
//data: data,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (str) {
alert("hai");
alert(str.st);
}
});
</script>
<body>
<input name="photos" id="photos" type="file" />
<input type="button" value="save" id="save" />
</body>
我的控制器文件看起来像
My controller file looks like
public ActionResult Details(HttpPostedFileBase data)
{
try
{
data = Request.Files[1];
byte[] imageSize = new byte[data.ContentLength];
data.InputStream.Read(imageSize, 0, (int)data.ContentLength);
Image g = new Image();
g.Img = imageSize;
dbContext.Add(g);
dbContext.SaveChanges();
return RedirectToAction("Index");
}
catch
{
}
var str = new { st = "saved" };
return Json(str, JsonRequestBehavior.AllowGet);
}
当我上传文件并单击保存按钮时，我的控制器获取了空文件.html5中是否有任何方法来传输文件.如果是，请给我任何建议.
