 * Hi all,
 * How do I correctly load jquery into wordpress admin? I want to use the jquery
   datepicker for a custom meta box.
 * I have read article [http://codex.wordpress.org/Function_Reference/wp_enqueue_script](http://codex.wordpress.org/Function_Reference/wp_enqueue_script).
   
   I do know that wordpress loads its own version of wordpress and I want to deregister
   that so that I can load jquery.ui.datepicker.js, a local file. Also, I am facing
   this javascript error and I have no idea on how to resolve this. Can’t get datepicker
   to load and this error is always there. Any advise is appreciated. Thanks.
