Making an ajax request to tornado 19.07.14

here is a example form called stocker.
after clicking the send button it will collect all formdata
and than it will send it to the JQuery.postJSON function,
there it adds the xsrf security fingerprint and making the ajax call to tornado,

on the tornado side it receives it on post and send the data back as a jonson dict what than forward it to its callback object Stocker.set

def post(self,idx=False):
    r={'_id':"mydata"}
    self.write(r)

jQuery("#stocker" ).click(function(e){
        var fdata= {'stocker':jQuery('#stocker').serialize()};
        jQuery.postJSON('http://localhost:8881/stocks',fdata,'Stocker.set')

});

function getCookie(name) {
    var r = document.cookie.match("\\b" + name + "=([^;]*)\\b");
    return r ? r[1] : undefined;
}

jQuery.postJSON = function(url, args, callback) {
    args._xsrf = getCookie("_xsrf");
    jQuery.ajax({url: url, data: jQuery.param(args), dataType: "text", type: "POST",
    success: function(response) {
    var funcCall = callback + "('" + response + "');";
    var ret = eval(funcCall);
    }});
};

var Stocker = {
  set: function(data) {
    r =  jQuery.parseJSON(data)
      console.log(r);
  }
}
