I have a calendar I display with only certain dates available and the rest disabled. I get all my dates and make up my calendar and it displays without problem
Try giving the form an id and then calling submit via an jquery id selector:
... $('#inlineDatepicker').datepick({ multiSelect: 999, minDate : '-14d', maxDate : '+2y', onSelect : function (dateText, inst) { $('#myFormID').submit(); // <-- SUBMIT LIKE THIS }, onDate : getAllowed(myValidDates), }).datepick('setDate',myNewDates);
