Get html across domains using jQuery and JSONP

Question

I have a form that outputs one simple html line <a href="link">A LINK</a>

I can directly access the process with data added to the URL, for example http://site.com/form.asp?sample=100

Since this happens across domains (in a subdomain), I am trying to do this using JSONP. I tried it first with datatype json, but I still got a ban on 403. That's what I'm trying to use with JSONP, but it's all messed up and returns an error with this% 5Bobject% 20Object% 5D added to it. I think this is a problem with how I try to add data to url?

$j.getJSON({
        type: 'POST',
        url: 'http://site.com/form.asp',
        data: 'order=' + ordervalue,
        contentType: "application/json; charset=utf-8",
        dataType: "jsonp",
        success: function(response) {
            alert(response);
        }
    });
