Using a simple JQuery ajax request how would I calculate the response size of the xml object that is being returned from my webserver? Is there a specific JQuery byte size method or could I simply use the .length method with a basic maths calculation, for instance: 

resultSize = (xmlObject.length / 1024);

Any help/suggestions would be appreciated.

  • Is requirement to return byte size of resource before request?, during request ? – guest271314 Mar 18 '15 at 07:58
  • I would just like to calculate the returned data in the ajax method. I think my calculation does work, for instance the default success: function(data, status, xhr) method. If I use the data object like: (data.length / 1024) this gives me a value in KB. Im just not sure if there is a better way to do this. – DeanMWake Mar 18 '15 at 08:00

  • What is application of returning response byte size ? Is requirement to return byte size of resource only ? or, perform a task with returned byte size of resource ? – guest271314 Mar 18 '15 at 08:27
  • If you read the tags that I have added this is for performance-testing. There are no requirements. I am doing this to check the byte size of the returned xml so I can edit the program accordingly if the objects are too big. – DeanMWake Mar 18 '15 at 09:07
  • Try `$.ajax({url:url, type:"HEAD"})` , open `console` -> select `Network` , select -> "Headers" -> scroll to "Content-Length" .
