Initialize datebox with blank and format data as dd-mm-yyyy (British format)

[thecyberzone]

Although there were so many threads exist in this forum with this discussion, just I am adding a small request to the developer. To use a databox with dd-mm-yyyy format just I have used following parser and formatter, everything is working fine except whenever a blank date is parsed/formatted within this datebox it always puts current date, (It should be, as per my code it is initialized with new Date), but what I require is to initialized with a blank date. The code I have used is :

Code:

	$.fn.datebox.defaults.formatter = function(date){
		if (!date){return ' ';}
		var y = date.getFullYear();
		var m = date.getMonth()+1;
		var d = date.getDate();
		return (d<10?('0'+d):d)+'-'+(m<10?('0'+m):m)+'-'+y;
	};
	$.fn.datebox.defaults.parser = function(s){
		if (!s) return new Date();
		var ss = s.split('-');
		var d = parseInt(ss[0],10);
		var m = parseInt(ss[1],10);
		var y = parseInt(ss[2],10);
		if (!isNaN(y) && !isNaN(m) && !isNaN(d)){
			return new Date(y,m-1,d);
		} else {
			return new Date();
		}
	};

Now what I have done in above code, in parser instead of returning simple new Date() I have used new Date(0,0,0) and in formatter function I have check that

Code:

if(date==Date(0,0,0)) {return ' ';}

, but his does not work, instead it returns 31-12-1899 !!! I don't know why.

So please anybody suggest me a way by which I can display a blank date in datebox when it is empty/blank.

The date 'new Date(0,0,0)' is not a blank date. Please try to use 'null' value instead. To let the 'parser' function work correctly, the calendar's 'moveTo' method should also be overridden.

Code:

$.extend($.fn.calendar.methods, {
	moveTo: function(jq, date){
		return jq.each(function(){
			if (!date){
				var now = new Date();
				$(this).calendar({
					year: now.getFullYear(),
					month: now.getMonth()+1,
					current: date
				});
				return;
			}
			var opts = $(this).calendar('options');
			if (opts.validator.call(this, date)){
				var oldValue = opts.current;
				$(this).calendar({
					year: date.getFullYear(),
					month: date.getMonth()+1,
					current: date
				});
				if (!oldValue || oldValue.getTime() != date.getTime()){
					opts.onChange.call(this, opts.current, oldValue);
				}
			}
		});
	}
});
$.extend($.fn.datebox.defaults, {
	formatter: function(date){
		if (!date){return ' ';}
		var y = date.getFullYear();
		var m = date.getMonth()+1;
		var d = date.getDate();
		return (d<10?('0'+d):d)+'-'+(m<10?('0'+m):m)+'-'+y;		
	},
	parser: function(s){
		if (!s) return null;
		var ss = s.split('-');
		var d = parseInt(ss[0],10);
		var m = parseInt(ss[1],10);
		var y = parseInt(ss[2],10);
		if (!isNaN(y) && !isNaN(m) && !isNaN(d)){
			return new Date(y,m-1,d);
		} else {
			return null;
		}		
	}
});

Thanks for your help, after adding moveTo method to the Calender, it works perfectly as I wanted.
