Validar y dar formato a Datebox jquery

[macajoda]

Yo pude solucionarlo colocando este escrip
<script type="text/javascript">
//Formatear el datebox Año/Mes/Dia
$('#Fecha').datebox({
value: (new Date().toString('yyyy-MMM-dd')), /* Date.js toString function to convert date into format that is being used by datebox. */
formatter : function(date){
var y = date.getFullYear();
var m = date.getMonth()+1;
var d = date.getDate();
return y+'-'+(m<10?('0'+m):m)+'-'+(d<10?('0'+d):d);
},
parser : function(s){
if (!s) return new Date();
var ss = (s.split('-'));
var y = parseInt(ss[0],10);
var m = parseInt(ss[1],10);
var d = parseInt(ss[2],10);
if (!isNaN(y) && !isNaN(m) && !isNaN(d)){
return new Date(y,m-1,d);
} else {
return new Date();
}
}
});

function myformatter(date){
var y = date.getFullYear();
var m = date.getMonth()+1;
var d = date.getDate();
return y+'-'+(m<10?('0'+m):m)+'-'+(d<10?('0'+d):d);
}

function myparser(s){
if (!s) return new Date();
var ss = (s.split('-'));
var y = parseInt(ss[0],10);
var m = parseInt(ss[1],10);
var d = parseInt(ss[2],10);
if (!isNaN(y) && !isNaN(m) && !isNaN(d)){
return new Date(y,m-1,d);
} else {
return new Date();
}
}
</script>
