Applying effects to jquery-ui tabs

Question

Is it possible to apply an effect to a jquery-ui tab, I haven't seen any examples of it, and I'm fairly sure that if it is possible the following is incorrect:

<script type="text/javascript">
    $(function() {
        $("#tabs").tabs();
        $("#tabs").effect(slide,options,500,callback);
    });
</script>

Answer 1

You can do something like this, if you want the effect to happen when you change tags using the fx option:

$(function() {
  $("#tabs").tabs( { fx: { height: 'toggle' } } );
});

A fade + slide would be like this:

$(function() {
  $("#tabs").tabs( { fx: { height: 'toggle', opacity: 'toggle' } } );
});

This applies the effects to the tabs themselves, you can take it for a spin here.

  $(function () {
        $("#tabs").tabs({
            beforeLoad: function (event, ui) {
                if (ui.tab.data("loaded")) {
                    event.preventDefault();
                    return;
                }
                ui.ajaxSettings.cache = false,
                ui.panel.html('<img src="images/loader.gif" width="24" height="24" style="vertical-align:middle;"> Loading...'),
                ui.jqXHR.success(function() {
                    ui.tab.data( "loaded", true );
                }),
                ui.jqXHR.error(function () {
                    ui.panel.html(
                    "Couldn't load Data. Plz Reload Page or Try Again Later.");
                });
            }
        });
    });
