Tengo un selector de fechas donde muestro dos meses y quiero elegir al azar 3 fechas en cada mes visible
$('.date').datepicker({
minDate: new Date(),
dateFormat: 'DD, MM, d, yy',
constrainInput: true,
beforeShowDay: processDates,
numberOfMonths: 2,
showButtonPanel: true,
showOn: "button",
buttonImage: "images/calendar_icon.jpg",
buttonImageOnly: true
});
Aquí está mi cálculo
var now = new Date();
var nowTime = parseInt(now.getTime()/1000);
var randomDateSet = {};
function getRandomSet(y,m) {
var monthIndex = "m"+y+""+m; // m20121 for Jan
if (randomDateSet[monthIndex]) return randomDateSet[monthIndex];
// generate here
.
. - I need this part
.
return randomDateSet[monthIndex];
}
function processDay(date) { // this is calculated for each day so we need a singleton for the array
var dateTime = parseInt(date.getTime()/1000);
if (dateTime <= (nowTime-86400)) {
return [false]; // earlier than today
}
var m = date.getMonth(), d = date.getDate(), y = date.getFullYear();
var randomDates = getRandomSet(y,m);
for (i = 0; i < randomDates.length; i++) {
if($.inArray((m+1) + '-' + d + '-' + y,randomDates) != -1 || new Date() > date) {
return [true,"highlight","Some message"];
}
}
return [true,"normal"]; // ordinary day
}
