如何在ajax中传递参数

I have ajax script which is working fine. Once it was success, I want to pass parameter like header("Location: tar.php?php=$value");

Till now I only know $("body").load("rumour.php"); Help me pass parameter like we do have in PHP

    $.ajax ({
        type: "POST",
        url: "update_comment.php",
        data: { id1: id, comment1: comment },

            success: function(data) {
                $("body").load("rumour.php");
            }
   );

Try this:

$("body").html(data);
