problem with jquery datepicker onselect

alex picture alex · Aug 13, 2009 · Viewed 70.8k times · Source

Following the basic onSelect spec on the jquery site I tried the following code:

<!DOCTYPE html>
<html>
<head>
  <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" />
  <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script>
  <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script>
  <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.datepicker.js"></script>
  <script type="text/javascript">
  $(document).ready(function(){
    $("#datepicker").datepicker();


$('#datepicker').datepicker({
   onSelect: function(dateText, inst) { alert("Working"); }
});



  });

  </script>
</head>
<body style="font-size:62.5%;">

<div type="text" id="datepicker"></div>

</body>
</html>

And can't get it to work! Originally been trying to get a more complicated thing to work but the onSelect was just not working so I went back to basics and still don't work, anyone any idea what I'm doing wrong??

You're not using the api correctly. Don't take it bad, it's confusing at first.

Both of these lines are telling the datepicker widget to initialize a datepicker on an element:

$("#datepicker").datepicker();
$('#datepicker').datepicker({
   onSelect: function(dateText, inst) { alert("Working"); }
});

You could remove the first one since it's not doing anything except preventing the second one from having any effect.

If you want to change the value of one of the options after you've already initialized the widget then you would need to use this api:

$('#datepicker').datepicker('option', 'onSelect', function() { /* do stuff */ });

Or alternatively, you could attach a handler using jQuery's bind function:

$('#datepicker').bind('onSelect', function() { /* do stuff */ });
