ruby-on-rails-4

I am following along in the latest Agile Web Development with Rails 4 book. In Chapter 11 (AJAX), the book instructs us to use the following code in the "create.js.erb" file:

if ($('#cart tr').length == 1) { $('#cart').show('blind', 1000); }

This code causes the #cart div to jump down without any content. After 1 second it appears. There is no sliding effect.

I tried using slideDown(); as well, but the div just appears immediately. Out of curiosity, I tried slideUp(); when the div was visible. Voila. The div slid up.

This appears to be a jQuery bug and wondered if anyone else has experienced this, or has any suggestions for me.

Thanks.
