jquery - Javascript: submit form specyfing content type -

i use code submit form

var form = $("#some-form"); form.attr("action", url); form.attr("method", "post"); form.attr('target', '_blank'); form.submit(); 

the problem request sent has content-type: application/x-www-form-urlencoded, (as mentioned here) encodes \n characters in textareas of form %0d%0a, decoded \r\n on server side , cause many troubles.

i want server receive \n, need content type.

so, questions are:

• what content type should use?
• how should change javascirpt use content type?

edit

i tried enctype="multipart/form-data", encodes new line characters same way.

use xmlhttprequest (ajax)

it asynchronous , submits data page. plus can specify header. \n should arrive \n on server ajax.

var request = new xmlhttprequest; request.method = "post"; request.open(request.method, [url] , true); //true asynchronous  //this part here matters. regular form data charset utf-8 request.setrequestheader("content-type", "application/x-www-form-urlencoded ; charset=utf-8"); request.setrequestheader("connection", "close");  request.onreadystatechange = [trackingfunction]; //you can see data returned post.  request.send([arg]); //send post arguments here! 

this seems work on machine. save data file , notepad doesn't register \n newline. should've when lf converted cr lf
