Subject: Fixed #2069. The ready helper and shortcuts act the same. You can also still bind... 
X-Git-Tag: 1.2.2b2~16
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=d1b9ad3cdb3fd226d4208ae6eaed98baf7026222;p=jquery.git

Fixed #2069. The ready helper and shortcuts act the same. You can also still bind, unbind and trigger the ready event on the document element but doing so follows the events API unlike the ready helper method.
