Parser error with jquery ajax?

Here is my code it returns a parser error and fails.

$.ajaxSetup({
  type: 'GET',
  url: 'http://www.example.com/ajax',
  dataType: 'json'
});

$('#addHotlink').click(function() {
  $('body').after('<div id="lightBox" style="height: ' + htmlHeight + 'px;"><div><h3>Choose a name for your hotlink:<img id="lightBoxClose" src="http://www.example.com/images/closedAccordion.png" height="17" width="17" alt="" title="Close this box" /></h3><form id="addHotlinkForm" action="#" method="post" autocomplete="off"><input id="hotlinkName" type="text" maxlength="15" /><input class="submit" type="submit" value="Add Hotlink" /></form></div></div>');
  $('#lightBox').hide().fadeIn('fast');
  return false;
});

$('#addHotlinkForm').live('submit', function(event) {
  event.preventDefault();

  var pageURL = window.location.href;  
  var hotlinkName = $('#hotlinkName').val();

  if (hotlinkName.length > 0) {
    $.ajax({
      data: {
        hotlinkName: hotlinkName, 
        hotlinkURL: pageURL
      },
      success: function() {

        alert('Your hotlink ' + hotlinkName + ' has been inserted to the url: ' + pageURL);
      },
      error: function (ajaxOptions, thrownError) {

        alert(thrownError);
        alert('V开发者_Python百科ar hotlinkName: ' + hotlinkName + ' Var hotlinkURL: ' + pageURL);
      }
    });
  }
});

I get a parser error when it tries to execute? Although in the error function the values are being returned as:

hotlinkName: Text entered into box,

hotlinkURL: The current address of page (http://www.example.com/home)

Why is this not working? I have tried changing the type to POST and it still doesn't work?

Here is a fiddle of what I am trying to do, but of course it fails as it is not linked to any ajax sheet.

It worked for me, if you are using jsfiddle to test your script change the ajaxsetup to the following

$.ajaxSetup({

    type: 'GET',
        url: '/echo/json/',
    dataType: 'json'
});

I have created this : a simple environment to test ajax based javascript using JQuery on jsfiddle. You can checkout the jsfiddle documentation for more.
