Where to add datepicker custom javascript?

Hello,

I am trying to customize by datepicker to block national holidays and some other useful dates which I don't want people to be allowed to select. I don't see this functionality in Gravity Forms datepicker so I would like to know where to add my javascript?

I have searched the forums and it says put in in your page template. I don't want to get out of my depth by just placing it anywhere. Would you be able to direct me to the template I should be editing to add this code or maybe I can do it directly in gravity forms via some snippet or something?

Thanks

Code I am trying to add:

<script type="text/javascript">
jQuery.noConflict();
  jQuery(document).ready(function($) {

$(".selector").datepicker({ beforeShowDay: nationalDays})   

natDays = [
  [1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'],
  [4, 27, 'za'], [5, 25, 'ar'], [6, 6, 'se'],
  [7, 4, 'us'], [8, 17, 'id'], [9, 7, 'br'],
  [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']
];

function nationalDays(date) {
    for (i = 0; i < natDays.length; i++) {
      if (date.getMonth() == natDays[i][0] - 1
          && date.getDate() == natDays[i][1]) {
        return [false, natDays[i][2] + '_day'];
      }
    }
  return [true, ''];
}

  });
</script>

Hi Rob,

Thanks for the suggestions. I actually found it easier to get a plugin "CSS & JavaScript Toolbox" which allows me to insert code snippets to the templates without mucking around in the code. That also helps me out with theme updates not overiding my changes.

Only issue I have left is formatting the date the way I need to . I asked about that here http://www.gravityhelp.com/forums/topic/how-to-format-date-as-full-dd-d-mm-yy-in-date-picker if you have any suggestions would be great to hear...

Cheers

Actually I was able to get this all working in the end.

Thanks
