I've constructed a datepicker using the basic template found here:
https://github.com/qodesmith/datepicker/blob/master/README.md
My code is:
const picker = datepicker(document.querySelector('#datepicker'), {
// Event callbacks.
onSelect: function(instance) {
var instanceSplit = instance.dateSelected.toString().split(" " ,4)
var instanceClean = instanceSplit.toString().replace(/,/g, ' ')
selectedDate = instanceClean
console.log(selectedDate)
update()
},
onShow: function(instance) {
console.log('Calendar showing.');
},
onHide: function(instance) {
console.log('Calendar hidden.');
},
onMonthChange: function(instance) {
// Show the month of the selected date.
},
// Customizations.
formatter: function(el, date, instance) {
// This will display the date as `1/1/2019`.
el.value = date.toDateString();
},
position: 'tr', // Top right.
startDay: 1, // Calendar week starts on a Monday.
customDays: ['S', 'M', 'T', 'W', 'Th', 'F', 'S'],
customMonths: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
overlayButton: 'Go!',
overlayPlaceholder: 'Enter a 4-digit year',
// Settings.
alwaysShow: true, // Never hide the calendar.
dateSelected: new Date(), // Today is selected.
maxDate: new Date(2019, 5, 21), // Jan 1st, 2099.
minDate: new Date(2016, 5, 1), // June 1st, 2016.
startDate: new Date(), // This month.
});
While it all works, I'd like to set the maxDate to be a week from today. While I know I could do something like:
var firstDay = new Date();
var nextWeek = new Date(firstDay.getTime() + 7 * 24 * 60 * 60 * 1000);
I can't figure out how to pass a variable into maxDate:
object. If I declare a maxDate variable in the formatter function, or globally, I'm not able to pass it into the object.
In fact, I can't really figure out how the entire code below is even working. I'm not sure what the formatter function is doing, nor am I clear on how the objects at the end relate to the function as a whole. Apologies for the somewhat general question, but I'm finding the datepicker documentation confusing.

maxDate: new Date(new Date().getTime() + 7 * 24 * 60 * 60 * 1000),
