如何在jQuery UI Datepicker中禁用下一个周末？

Question

In an order page I want to implement a calendar, in which, if the user is ordering on friday after 10am, then block the following saturday and sunday in delivery date calendar. Here is a sample code I am trying, but not working as intended.

beforeShowDay: function(date) {
    var day = dt.getDay();
    var hour = dt.getHours();
    if (day == 4) {
        // i think, here i want to put the code to disable days
    }
}

If I use something like this

beforeShowDay: function(date) {
    var day = date.getDay();
    var dt = new Date();
    var hour = dt.getHours();
    return [(day != 5 && day != 6)];
}

I am able to disable Sat and Sun days, but this will disable all the Sat and Sun days. I wnat to disable only the very next Sat n Sun days to be disabled. Also I can get current Hour in var hour, So where should I use the condition to check if the hour is greater than 10am, I am using something like this but not working

beforeShowDay: function(date) {
    var dt = new Date();
    var hour = dt.getHours();
    var day = date.getDay();
    if (day == 4 && hour >= 10) {
        return [(day != 5 && day != 6)];
    }
}

Inside the beforeShowDay function, check the current date to see if it is a Friday and after 10am. If this is true then you also need to check if the date passed as argument is the next Saturday or Sunday:

 $(function() { $("#datepicker").datepicker({ beforeShowDay: function(date) { // date (Friday March 13 2015 10:00 AM) is hardcoded for testing var now = new Date(2015, 3 - 1, 13, 10, 0, 0, 0); if (now.getDay() === 5 && now.getHours() >= 10) { var now_plus_1 = new Date(now.getTime()); now_plus_1.setHours(0, 0, 0, 0); now_plus_1.setDate(now_plus_1.getDate() + 1); var now_plus_2 = new Date(now.getTime()); now_plus_2.setHours(0, 0, 0, 0); now_plus_2.setDate(now_plus_2.getDate() + 2); return [date.getTime() !== now_plus_1.getTime() && date.getTime() !== now_plus_2.getTime(), ""]; } return [true, ""]; } }); }); 

 @import url("//ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/ui-darkness/jquery-ui.min.css"); body { font-size: smaller; } 

 <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script> <input id="datepicker">

$('#datepicker').datepicker({
    beforeShowDay: function(date){
        var dt = new Date(),
            day = dt.getDay(),
            hour = dt.getHours(),
            twoDaysFrmNow = new Date().setDate(dt.getDate() + 2);
        return [!(day == 5 && hour >= 10 && date <= twoDaysFrmNow &&  date > dt)];
    }
});

beforeShowDayType: Function( Date date )

Default: null

A function that takes a date as a parameter and must return an array with:

[0]: true/false indicating whether or not this date is selectable [1]: a CSS class name to add to the date's cell or "" for the default presentation [2]: an optional popup tooltip for this date

The function is called for each day in the datepicker before it is displayed.

beforeShowDay: function(date) {
     var day = dt.getDay();
                         var hour = dt.getHours();
                        if( day == 4) {
                           // this is an example of how to use
                            //first parameter is disable or not this date
                            //second parameter is the class you want to add ( jquery will remove the click listener, but you probebly want to style it like this date is not available
                            //third optional tootltip like 'closed on weekends'
                             return [false,'disabled','weekend']
                        }

                    }
