The Basics: jQuery Datepicker in APEX
Wrap it up
Do the same for P1_MAX_DATE using the code:
$(“#P1_DATE”).datepicker( “option”, “maxDate”, $(“#P1_MAX_DATE”).val());
Just two statements! See for yourself and visit the demo page. Of course the variations of this approach are countless, but the basic two statements will remain: getting the value and setting the range options.
Have fun APEX-ing.
