date picker

date picker

I am using the date picker function:
function Datepicker() {
this.debug = false; // Change this to true to start debugging
this._curInst = null; // The current instance in use
this._keyEvent = false; // If the last event was a key event
this._disabledInputs = []; // List of date picker inputs that have been disabled
this._datepickerShowing = false; // True if the popup picker is showing , false if not
this._inDialog = false; // True if showing within a "dialog", false if not
this._mainDivId = 'ui-datepicker-div'; // The ID of the main datepicker division
this._inlineClass = 'ui-datepicker-inline'; // The name of the inline marker class
this._appendClass = 'ui-datepicker-append'; // The name of the append marker class
this._triggerClass = 'ui-datepicker-trigger'; // The name of the trigger marker class
this._dialogClass = 'ui-datepicker-dialog'; // The name of the dialog marker class
this._disableClass = 'ui-datepicker-disabled'; // The name of the disabled covering marker class
this._unselectableClass = 'ui-datepicker-unselectable'; // The name of the unselectable cell marker class
this._currentClass = 'ui-datepicker-current-day'; // The name of the current day marker class
this._dayOverClass = 'ui-datepicker-days-cell-over'; // The name of the day hover marker class
this.regional = []; // Available regional settings, indexed by language code
this.regional[''] = { // Default regional settings
closeText: 'Done', // Display text for close link
prevText: 'Prev', // Display text for previous month link
nextText: 'Next', // Display text for next month link
currentText: 'Today', // Display text for current month link
monthNames: ['January','February','March','April','May','June',
'July','August','September','October','November','December'], // Names of months for drop-down and formatting
monthNamesShort: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'], // For formatting
dayNames: ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'], // For formatting
dayNamesShort: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'], // For formatting
dayNamesMin: ['Su','Mo','Tu','We','Th','Fr','Sa'], // Column headings for days starting at Sunday
weekHeader: 'Wk', // Column header for week of the year
dateFormat: 'yy-m-d',
firstDay: 0, // The first day of the week, Sun = 0, Mon = 1, ...
isRTL: false, // True if right-to-left language, false if left-to-right
showMonthAfterYear: false, // True if the year select precedes month, false for month then year
yearSuffix: '' // Additional text to append to the year in the month headers
};

and I would like to know how I can change the way that it submits to the server....I would like it to submit as yy-m-d and display as mm/dd/yy....is there a way to do this?
