6. jQuery Ajax File Upload

Question

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.

Answer 1

file upload is not possible through ajax. You can upload file, without refreshing page by using IFrame. you can check further detail 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+
