ajax response byte size

Question

I\'m using jQuery\'s getJSONP and I want to log the duration of the call and the size of the response to be able to have some statistics about the usage of my application.

Answer 1

you can get the "Content-Length" of the response header:

var contentsize;
$.ajax('url', function(data, textstatus, request) {
    contentsize = request.getResponseHeader("Content-Length") / 1024;
    //do stuff with your data
});

Answer 2

$.ajax('url',function(data,textstatus,request)
{
     var totalBytes  = request.getResponseHeader('Content-length');

     //if u are looking for downloaded bytes
     var dlBytes =request.responseText.length; 
});
