Can I use the following jQuery code to perform file upload using POST method of an ajax request ?
$.ajax({
type: "POST",
timeout: 50000,
url: url,
data: dataString,
success: function (data) {
alert('success');
return false;
}
});
If it is possible, do I need to fill data part? Is it the correct way? I only POST the file to the server side.
I have been googling around, but what I found was a plugin while in my plan I do not want to use it. At least for the moment.

File upload is not possible through AJAX.
You can upload file, without refreshing page by using IFrame .
You can check further details here.
UPDATE
With XHR2, File upload through AJAX is supported. E.g. through FormData object, but unfortunately it is not supported by all/old browsers.
FormData support starts from following desktop browsers versions.
- IE 10+
- Firefox 4.0+
- Chrome 7+
- Safari 5+
- Opera 12+
For more detail, see MDN link.
