I have an html document which has a 1 column table holding  jquery datepicker(see attached code).

When I simply attach the datepicker using:

               //code lines 31 onwards
            $('.date-pick').each(function(){
                $(this).datepicker();
            });

the table loads quikcky, but when I extend the datepicker functionality as follows:

            $('.date-pick').each(function(){
                $(this).datepicker();
                  $(this).datepicker('option', {dateFormat: 'dd/mm/yy'});
                  $(this).datepicker('option', {autoSize: true });
                  $(this).datepicker('option', {showButtonPanel: true });
                  $(this).datepicker('option', {onClose: function(dateText, inst) {
                              //close handler
                              //checkAndUpdateDate(dateText, inst);
                        }
                  });
                  $(this).datepicker('option', {onBlur: function(dateText, inst) {
                              //blur handler
                              //checkAndUpdateDate(dateText, inst);
                        }
                  });
            });
the page takes a long time to load and if too many rows are used, thepage script freezes.

How can I customize the behaviour of the datepicker without causing a delay?

What browser are you using? IE 6 is particularly slow when doing anything with javascript, try loading the "slow" page in the latest version of firefox or chrome and see if it's any faster.

Thank you Crisco 96, I am using FF and it wasn't a browser issue.

Thank you HainKurt, setDefaults is what I was looking for.
