While creating form , we mostly require date field and if it is dynamic it gets more easy to select date. By using jQuery date format in forms, we will be able to change the format of the date by selecting any one from the given formats.

This blog posts will show you how to add date picker along with multiple formats. All this can be possible just by including jQuery UI to your HTML form as follows:

<!------------ Including  jQuery Date UI with CSS -------------->
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
<script src="http://code.jquery.com/ui/1.11.0/jquery-ui.js">
</script>

In our example, when user focus on input field by clicking on it or using tab key,   below jQuery code popups calender for choosing date, another field in our form allows user to select desired date format.

$(function(){
$( "#datepicker" ).datepicker();
//Pass the user selected date format
$( "#format" ).change(function() {
$( "#datepicker" ).datepicker( "option", "dateFormat", $(this).val() );
});
});

Just watch our live demo or go through our codes and download it to use to make it work.
