javascript - Jquery 1.11.1 - download file and additional callback -

i have form submit django server calling.

$("#my_form").submit(); 

it server returns xml file executing code:

content = some_data_retrieved_from_database_as_xml() response = httpresponse(content, content_type='text/xml') response['content-disposition'] = 'attachment; ' response['content-disposition'] += 'filename=my_file.xml' response['content-encoding'] = 'utf-8' return response 

google chrome downloads file, want register additional callback function, called myfunction(data).

chrome should download file , next call myfunction(this xml file).
tried code, doesn't work:

$("#my_form").bind('ajax:complete', myfunction); 

i tried use $.post, after callback function called , unfortunatelly file not downloaded.

so want post asynchronously, download returned file, , execute callback. 1 possibility "fake" download link:

$.post(post_url, post_data, function(response) {   var = document.createelement('a');   a.setattribute('href', 'data:'     + response.contenttype     + ';charset='     + response.inputencoding     + ','     + new xmlserializer().serializetostring(response));   a.setattribute('download', download_filename);   a.click();   // file download triggered    myfunction();   // additional callback action });

update

as zoran majstorovic mentioned in comment, can try jquery plugin: http://johnculviner.com/jquery-file-download-plugin-for-ajax-like-feature-rich-file-downloads/

just include the source , then

$.filedownload(post_url, {   httpmethod: "post",   successcallback: myfunction }); 

for security, need set cookie

set-cookie: filedownload=true; path=/
