I\'m trying to submit a form with a file field in it via jQuery.Form plugin, here\'s the code:
$(\'form\').ajaxSubmit({
url: \"/path\",
data
Same situation than you folks : the problem only occurs with enctype="multipart/form-data" form used with $(form).ajaxSubmit(...) function.
My team and I had to replace (in this function) dataType: 'json' option with dataType: 'text' and add responseText = $.parseJSON(responseText); to force server response parsing.
Of course we also had to step in server side to return a response with "text/plain" header instead of "application/json"
We're not proud of it :( IE is definitely killing everything...
I didn't try the advice given by zmonteca (already spent too much time on it) but it seems worthy : let us know if it was OK for you.
Hope it helps!
