jQuery - how to alter Datepicker settings after it has been initialized

Question

I would like to bind to initialized datepicker "onSelect" function.

I've been trying hard to find a solution on the web, but was unsuccessful.

Anyone can tell me how to do it?

Answer 1

You can simply use the setter

$('#datepicker').datepicker();
$('#datepicker').datepicker("option", "onSelect", function(){alert('hi')});

Answer 2

I found the above solutions caused problems in my case. Setting onSelect after the datepicker has already been initialised seems to cause the datepicker to be reinitialised. This may not be desirable.

If you are having problems it may be necessary to go through the back-door. This could have compatibility issues when JQUI is updated, but if you are willing to deal with that, then this code could help you out...

var inst = $.datepicker._getInst($('#startdate').get(0));
inst.settings.onSelect = function (dt) {
    // your code here
};
