[jQuery] display returned data from posting page

[jQuery] display returned data from posting page


I need to do a post and then have the posting page return some data
into a var. I've tried a few things but can't seem to get it to
work. Please see my pseudo code below. How can I have the posting
page return data via json?
jQuery.post(container.url, {
"data1":1},
function(){
var rData=data from posting page
});
Thanks!
