I am using xdan/datetimepicker and can not make that data highlights were binded dynamicaly.
var MainViewModel = function(app) {
var self = this;
var $parent = app;
self.dataAvailability = {};
self.highlightedDates = ko.observable(undefined); //ko.observableArray([]);
//Then I have method to query available data in DB, endpoint returns array like this: [2016-09-27T00:00:00.0000000+03:00,2016-09-29T00:00:00.0000000+03:00]
self.UpdateDataAvailabilityHighlight = function(timeString) {
var url = String.format(config.urls.dataAvailability, settings.location());
var dTime = moment(timeString, "DD/MM/YYYY H:mm:ss").toDate();
var id = dTime.getFullYear() + "" + dTime.getMonth();
$.getJSON(url, data).done(function(result) {
var highlights = [];
//Using lodash
result.forEach(function(element, index) {
highlights.push(moment(element).format("DD/MM/YYYY").toString() + ",,xdsoft_highlighted_mint");
});
self.dataAvailability[id] = highlights;
})
self.highlightedDates(self.dataAvailability[id] || []);
}
}
module.exports = MainViewModel;
self.mainView = new MainViewModel(self);
//Knockout Binding
(function (ko) {
ko.bindingHandlers.datetimepicker = {
init: function (element, valueAccessor, allBindingsAccessor, viewModel, bindingContext) {
var $element = $(element);
var value = valueAccessor(), allBindings = allBindingsAccessor();
var valueUnwrapped = ko.utils.unwrapObservable(value);
var options = allBindings.dtPickerOptions || {};
var myFormatter = {
parseDate: function (vDate, vFormat) {
return moment(vDate, vFormat).toDate();
},
guessDate: function (vDateStr, vFormat) {
return moment(vDateStr, vFormat).toDate();
},
parseFormat: function (vChar, vDate) {
return vDate;
},
formatDate: function (vChar, vDate) {
var res = moment(vChar).format(vDate);
return res;
}
};
$.datetimepicker.setDateFormatter(myFormatter);
$element.datetimepicker({
step: 15,
format: "DD/MM/YYYY H:mm:ss",
formatTime: "H:mm",
formatDate: "DD/MM/YYYY",
yearStart: 2000,
yearEnd: (new Date().getFullYear()) + 1,
highlightedDates: bindingContext.$data.highlightedDates(), // should ne binding, but dataTimePicker looks like can not handle dynamicaly changed values
onChangeDateTime: function (dp, $input) {
var date = moment($input.val(), "DD/MM/YYYY H:mm:ss");
date.set('second', 0);
var observable = valueAccessor();
observable(date.format("DD/MM/YYYY H:mm:ss"));
},
onShow: function (ct) {
bindingContext.$data.UpdateDataAvailabilityHighlight(ct);
this.setOptions({ highlightedDates: bindingContext.$data.highlightedDates() }); //Without this highlightedDates does not work
},
onChangeMonth: function (ct) {
bindingContext.$data.UpdateDataAvailabilityHighlight(ct);
this.setOptions({ highlightedDates: bindingContext.$data.highlightedDates() }); //Without this highlightedDates does not work
//SO when month is changed the "bindingContext.$data.highlightedDates" still does not get/updated the data. And if we wait some time and when results are returned, the days highlights are not updated.
}
});
},
update: function (element, valueAccessor) {
var valueUnwrapped = ko.utils.unwrapObservable(valueAccessor());
var obs = valueAccessor();
$(element).val(moment(valueUnwrapped, "DD/MM/YYYY H:mm:ss").format("DD/MM/YYYY H:mm:ss"));
}
};

</div>There main parts of my code. Check comments. So main problem is that "onChangeMonth" the days highlights are not updated from "self.highlightedDates". What I am doing wrong? Is it posiible that days highlight was updated dynamicaly when callender is displayed and results are get? And how to do it?
Note: This post/code snipped maybe be usefull - xdan/datetimepicker use “momenjs” instead default “php-date-formatter”.
Found how to update calendar view when I have results:
In knockout bindings I called method to get data passing the HTML doom element of datetimepicker.
$element.datetimepicker({
...
onShow: function (ct) {
bindingContext.$data.UpdateDataAvailabilityHighlight(ct, true, element);
},
onChangeMonth: function (ct) {
bindingContext.$data.UpdateDataAvailabilityHighlight(ct, true, element);
},
...
});
I added "then" action in jquery getJson method and in it I update the datapicker option:
$(element).datetimepicker({highlightedDates: self.highlightedDates()});
Full get data method:
$.getJSON(url, data)
.done(function(result) {
var highlights = [];
result.forEach(function(element, index) {
highlights.push(moment(element).format(config.timeFormatDate).toString() + ",Data is awailable," + config.timePickerHighlightStyle);
});
self.dataAvailability[id] = highlights; //Add empty data to, that it was not queried second time
})
.fail(function() { self.notificationController.addError("Failed to retrieve data availability"); })
.then(function () {
if (updateHilight) {
self.highlightedDates(self.dataAvailability[id] || []);
}
if (!(typeof element === "undefined")) {
$(element).datetimepicker({highlightedDates: self.highlightedDates()});
}
});
And now days highlight works like a charm :).
