Disable specific dates using datepicker in Angular Material

Question

I'm trying to disable specific dates in a calendar so a user can't select the dates in question - please see https://plnkr.co/edit/PwCLKWPQU0s3habxgUly?p=preview.

The only issue here is that I can only disable one date when returning the value to the filter, whereas in this case there are two example dates I was wanting to disable. I can also hard-code the two dates in the return statement, yet for my actual project the array of disabled dates is unknown.

Here is the JS:

var bookedDates = [new Date(2016, 10, 25).toString(), new Date(2016, 10, 10).toString()];

$scope.onlyWeekendsPredicate = function (date) {
    var day = date.getDate();
    var month = date.getMonth();
    var year = date.getFullYear();
    var todaysDate = new Date (year, month, day).toString();

    var confirmedBookingDates = [];

    for (var n = 0; n <= bookedDates.length; n++) {
        if (todaysDate != bookedDates[n]) {
            confirmedBookingDates[n] = true;
        }
        return confirmedBookingDates[n];
    }

};

If you have the bookedDates let say from a DB returned into array like you do above you can use a $filter to handle bookings. Codepen

Hi again, thanks for the suggestion and yes we will be using an external DB. I've tried running the code above and the 'filterBookings' isn't recognised?

alphapilgrim Over a year ago

how did you include it? make sure you request $filter in your controller, so it registers the $filter provider in the ctrl.

Richard Ansell Over a year ago

That's right, managed to fix that bit. However, the second date of the 'bookedDates' array is not showing in the calendar though

alphapilgrim Over a year ago

@RichardAnsell Will update, no need for $filter then. Please see update.

That's brilliant - thank you again! A lot simpler to manage now for reading from a DB as well

Its working, you can use php variable for dynamically disable the dates, you can bind this value from database to get dynamic output.

for disable date, use !== sign

Just copy paste the following code and checkout

two days + weekend for alphagrim:

function filterBookings() {
return function(date, bookedDates) {
    var day = date.getDay();
    if(day === 1 || day === 2 || day === 3 || day === 4 || day === 5){
        var sw = 0;
          for(var i =0; i < (bookedDates.length); i++) {
              if(date.toString().trim() === bookedDates[i].toString().trim()){
                sw = 1;
              }
          }
        if(sw==0){
          return date.toString();
        }
    }
};
