Datepicker, show only previous months

Question

I'm using jquery datepicker for selecting some dates, but I don't want to show the current month, just the previuos months. How can I get it?

At the moment I got the next code, but how can I select all the days of the last months?

$("#toDate").datepicker({
    maxDate: "-1M",
    dateFormat: 'dd/mm/yy',
    firstDay: 1,
    onSelect: function(selected) {
        var today = getDate();
        alert(today);
        $("#fromDate").datepicker("option", "maxDate", selected)
    }
});

Answer 1

To my knowledge, the only way to get all the day of the previous month is by setting maxDate to the last day of the previous month.

var d = new Date(); // current date
d.setDate(1); // 1st of the month
d.setHours(-1); // one hour before the 1st of the month (last day of previous month)
$("#toDate").datepicker({ 

maxDate: d,
dateFormat: 'dd/mm/yy',
firstDay: 1,
    onSelect: function(selected) {
    var today = getDate();
    alert(today);
       $("#fromDate").datepicker("option","maxDate", selected)
    }
});
