javascript - jQuery Ajax File Upload -


can use following jquery code perform file upload using post method of ajax request ?

$.ajax({     type: "post",     timeout: 50000,     url: url,     data: datastring,     success: function (data) {         alert('success');         return false;     } }); 

if possible, need fill "data" part? correct way? post file server side.

i have been googling around, found plugin while in plan not want use it. @ least moment.

file upload not possible through ajax. can upload file, without refreshing page using iframe. can check further detail here

update:

with xhr2, file upload through ajax supported. e.g. through formdata object, unfortunately not supported all/old browsers.

formdata support starts following desktop browsers versions. ie 10+, firefox 4.0+, chrome 7+, safari 5+, opera 12+
