jQuery effect after pressing button Drupal 6. I try to add jquerry effect after pressing button     

$(function(){
    $('.node-add-to-cart').click(function() {
      $(".prod-pic").effect("transfer", { to: $("#block-uc_cart-0") }, 1000);
    });
});


But I get error object# has no method 'effect'.
I created a custom js file with this code and put a link to the template.php using drupal_add_js.
According to status report Jquerry UI 1.6 is installed. However, when inspecting html code, among scripts there is no jquery.ui loaded. Should I call it from my custom js file?
Drupal 6 version of JQuery is 1.26 and after install jquery_update it will be updrade to 1.3.2

If you want persist use jquery method likes effect maybe this article,but I think you can't using jquery 1.6 or upper in Drupal 6 .( I don't told you it's impossible but achieve this job is more struggle and maybe cause problem in other part of your site ).

maybe this question be helpful for you.
