[jQuery] JSON in jQuery

[jQuery] JSON in jQuery


I am creating a widget where someone can post a note about the page
(feedback). I am currently using AJAX to pass the information to my
server, but I want to now use JSON, so that I can put it on one of my
other domains and still send the info to my original domain. This is
the function I currently have:
function saveNote(obj, cancel) {
var note_html = $(obj).parents(".note");
var page_id = getPageId($(obj));
if(!cancel) {
var t = note_html.find("textarea").val();
var url = G_MAIN_DOMAIN + "/page/addNote";
$.post(url, { page_id: page_id, note: t },function(data){});
} else {
var t = cancel;
}
if(t=='') t='(click to add text)';
note_html.html("<a href='#' class='edit_note'>" + t + "</
a>");
}
I want to change the $.post to something that sends out a JSON
object. Do I need to create another function or how do I do this?
Thanks for the help!
