** @ ребята, которые прокомментировали: я пытался реализовать это.
<script type="text/javascript">
$(document).ready(function() {
$('#holidayDate').datepicker();
var availableTags = ["New years Day", "Martin Luther King Day", "Groundhog Day", "Valentine's Day", "Washington's Birthday",
"Easter", "Earth Day", "National Arbor Day", "Mother's Day", "Memorial Day", "Flag Day", "Father's Day", "Independence Day",
"Labor Day", "Columbus Day", "Halloween", "Veterans Day", "Thanksgiving Day", "Pearl Harbor Remembrance Day", "Christmas Day"];
$("#tags").autocomplete({source:availableTags});
$('#holidayDate').change(function() {
var dateString = $(this).val().substring(0, 5);
var res = "";
switch (dateString) {
case '01/01': res = availableTags[0]; break;
case getThirdMondayInJanuary(): res = availableTags[1]; break;
case '02/02': res = availableTags[2]; break;
case '02/14': res = availableTags[3]; break;
case '04/22': res = availableTags[6]; break;
case '06/14': res = availableTags[10]; break;
case '07/04': res = availableTags[12]; break;
case '10/31': res = availableTags[15]; break;
case '11/11': res = availableTags[16]; break;
case '12/07': res = availableTags[18]; break;
case '12/25': res = availableTags[19]; break;
}
$('#tags').val(res);
});
});
