Javascript Booking Year Calendar

I'm looking for year calendar with select range functions, but i don't found this. And I decided customize Bootstrap Year Calendar - http://www.bootstrap-year-calendar.com/
And I'm stuck, my customised version is on http://ngrdanjski.com/calendar/
and I'm looking for help!
I added:
All days are disabled by default.
You can added Price periods, in this dates period you have enabled booking.
I want to add option when first click on the day it's first day of booking range, and second click is last day of booking range. Right now when click on day you have enable start date/first day, but when you click second time on day when you want to select end date, it's again start/first date. I wan't to have function to select start and end date. First click on day is start and second is end.
Code for current behavior is:
if(this.options.enableRangeSelection) {
cells.mousedown(function (e) {
if(e.which == 1)
{
var currentDate = _this._getDate($(this));
//console.log(currentDate);
if(_this.options.allowOverlap || _this.getEvents(currentDate).length == 0)
{
_this._mouseDown = true;
_this._rangeStart = _this._rangeEnd = currentDate;
_this._refreshRange();
}
}
});
cells.mouseenter(function (e) {
//console.log(e);
if (_this._mouseDown)
{
var currentDate = _this._getDate($(this));
if(!_this.options.allowOverlap)
{
var newDate = new Date(_this._rangeStart.getTime());
if(newDate < currentDate)
{
var nextDate = new Date(newDate.getFullYear(), newDate.getMonth(), newDate.getDate() + 1);
while(newDate < currentDate)
{
if(_this.getEvents(nextDate).length > 0)
{
break;
}
newDate.setDate(newDate.getDate() + 1);
nextDate.setDate(nextDate.getDate() + 1);
}
}
else
{
var nextDate = new Date(newDate.getFullYear(), newDate.getMonth(), newDate.getDate() - 1);
while(newDate > currentDate)
{
if(_this.getEvents(nextDate).length > 0)
{
break;
}
newDate.setDate(newDate.getDate() - 1);
nextDate.setDate(nextDate.getDate() - 1);
}
}
currentDate = newDate;
}
var oldValue = _this._rangeEnd;
_this._rangeEnd = currentDate;
if (oldValue.getTime() != _this._rangeEnd.getTime())
{
_this._refreshRange();
}
}
});
/* $(window).mouseup(function (e) {
if (_this._mouseDown)
{
_this._mouseDown = false;
_this._refreshRange();
var minDate = _this._rangeStart < _this._rangeEnd ? _this._rangeStart : _this._rangeEnd;
var maxDate = _this._rangeEnd > _this._rangeStart ? _this._rangeEnd : _this._rangeStart;
_this._triggerEvent('selectRange', {
startDate: minDate,
endDate: maxDate,
events: _this.getEventsOnRange(minDate, new Date(maxDate.getFullYear(), maxDate.getMonth(), maxDate.getDate() + 1))
});
}
}); */

I don't have skill for this functionality, please help.
Tnx!

I edited your code a bit. I understand that you want to set two dates, the start and the end of the range, and all that happens in two clicks. I also added a check if the second date is after the first one, if it's not they will swap places, so the earlier date is the rangeStart. The dates are stored in rangeStart and rangeEnd:
Edit: here's a pen
cells.mousedown(function (e) {
if(e.which == 1)
{
var currentDate = _this._getDate($(this));
//console.log(currentDate);
if(_this.options.allowOverlap || _this.getEvents(currentDate).length == 0)
{
if(!_this._mouseDown) {
_this._mouseDown = true;
_this._rangeStart = _this._rangeEnd = currentDate;
_this._refreshRange();
}
else {
_this._mouseDown = false;
_this._rangeEnd = currentDate;
if(_this._rangeEnd.getTime() < _this._rangeStart.getTime()) {
var tempDate = _this._rangeEnd;
_this._rangeEnd = _this._rangeStart;
_this._rangeStart = tempDate;
}
// _this._refreshRange();
}
}
if(_this._rangeStart != _this._rangeEnd) {
console.log(_this._rangeStart.getDate() + ',' + _this._rangeEnd.getDate());
}
}
});

Why my focus is not working properly?

I have data.json file is being loaded after I focus but after I focus then my datepicker is not showing why I didn't understand. but if I focus second time I can see.. where is my mistake ?

return arr.map(function(item) {
return item.field
})
}
$(function() {
var focused = false;

$.getJSON has a done() function in which you can write you logic after data is loaded. You can trigger the datepicker manually inside the done function
Here's a working fork

It is because, on the first focus, the datepickers are applied on the elements and NOT triggered. Mind the difference between binding an event and triggering it.
On the first time focus, datepicker will be applied and NOT triggered as it is not already bound to the element. But on any subsequent focus, it would trigger the datepicker and open it since it is already bound to the element.
As a solution,you can try adding $("#checkin").datepicker('show'); and $("#checkout").datepicker('show'); after the end for $("#checkin").datepicker({}) and $("#checkout").datepicker({}), respectively.

You should load your data prior to the first focus event on your datepickers.
Here's an example :
plunkr
$( document ).ready(function() {
var data;
$.getJSON('data.json', function (d) {
data = d;
console.log('data', d);
setupDatepickers();
});
function setupDatepickers() {
// use ajax data mapped to same structure as original variables
var firstDate = flattenFieldsArray(data.firstDate);
var lastDate = flattenFieldsArray(data.lastDate);
var availabledays = flattenFieldsArray(data.availabledays);
var booked = flattenFieldsArray(data.booked);;
var ssdays = [];
// nothing was changed below
var dateFormat = "mm/dd/yy",
from = $("#checkin")
.datepicker({
beforeShowDay : function (date) {
var y = date

var m = (date.getMonth() + 1).toString(); // get month.
var d = date

row delete but not removing the corersponding value from the total from the label using jquery

Currently working on jquery date picker with my current code where I can able to clone the row and i can able to add years and months. But when i try click add more it will create one more row and again i can able to add from date and to date it was calculating perfectly but when i click the delete button it was deleting the row but not removing the corresponding value.
here is what i tired for delete
$(document).on('click', ".btn_less1", function() {
var len = $('.cloned-row3').length;
if (len > 1) {
$(this).closest(".btn_less1").parent().parent().parent().remove();
uppdiff();
}
});
Here is the fiddle link for rest of the code
Thanks in advance

The order you defined your function was wrong, the function uppdiff was not found since it was defined much later. I rearranged your code as shown below:
$(function() {
var diffDays = 0;
$.datepicker.setDefaults({
dateFormat: "mm/dd/yy",
changeMonth: true,
yearRange: "-100:+0",
changeYear: true,
maxDate: new Date(),
showButtonPanel: false,
beforeShow: function() {
setTimeout(function() {
$('.ui-datepicker').css('z-index', 99999999999999);
}, 0);
}
});
var valid = true;
function uppdiff() {
if (valid) {
var dateStart = [];
var dateEnd = [];
$.each($('.datepicker'), function() {
if ($(this).hasClass('startDate'))
dateStart.push($(this).datepicker('getDate'))
else
dateEnd.push($(this).datepicker('getDate'))
});
diffDays = 0;
$.each(dateStart, function(key, value) {
$.each(dateStart, function(key2, value) {
if (key !== key2 && !(dateStart[key] >= dateEnd[key2] || dateEnd[key] <= dateStart[key2])) {
alert('Date ranges overlap');
valid = false;
return valid;
}
});
diffDays += parseInt((dateEnd[key] - dateStart[key]) / (1000 * 60 * 60 * 24));
return valid;
});
var year = parseInt(diffDays / 365);
var date = diffDays - (365 * year);
var month = parseInt(date / 30);
//document.getElementById("txt_expy").innerHTML = year + " year";
//document.getElementById("txt_expm").innerHTML = month + " Month";
if(year >= 0){
$("#txt_expy").text(year + " year");
}
if(month >= 0){
$("#txt_expy").text(month + " Month");
}
}
}
$(".cloned-row3").find(".datepicker").removeClass('hasDatepicker').datepicker();
var count = 0;
$(document).on("click", ".exp_add_button", function() {
var $clone = $('.cloned-row3:eq(0)').clone(true, true);
$clone.find('[id]').each(function() {
this.id += 'someotherpart'
});
$clone.find('.btn_more').after("<input type='button' value='Delete Row' class='btn_less1 selbtnless' id='buttonless'/>")
$clone.attr('id', "added" + (++count));
/*$clone.find(".degree_Description").attr('disabled', true).val('');*/
$clone.find("input.startDate,input.endDate")
.val('')
.removeClass('hasDatepicker')
.removeData('datepicker')
.unbind()
.datepicker();
$(this).parents('.wrk_exp').after($clone);
});
$(document).on('change', ".datepicker", function() {
var valid = true;
$.each($('.datepicker'), function() {
if ($(this).val() == "") {
valid = false;
return false;
}
uppdiff();
});
uppdiff();
});
$(document).on('click', ".btn_less1", function() {
var len = $('.cloned-row3').length;
if (len > 1) {
$(this).closest(".btn_less1").parent().parent().parent().remove();
uppdiff();
}
});
});
Here is the updated JSFiddle

Disabling dates and specific weekdays in jquery datepicker

I'm trying to disable specific dates (i.e christmas etc) PLUS disabling certain weekdays per default in the jQuery UI datepicker, but I can't get it to work. I have the following:
<script type="text/javascript">
iDays = 2;
blockDays = [1,4,6];
$(document).ready(function () {
$.datepicker.setDefaults($.datepicker.regional['sv']);
$('.inpDate').datepicker({
dateFormat: 'yy-mm-dd',
minDate: iDays,
maxDate: 14,
showOtherMonths: true,
showStatus: true,
beforeShowDay: noHolidays
});
var disabledDays = ["12-24-2013", "12-25-2013", "12-26-2013", "12-31-2013", "1-1-2014"]
function noHolidays(date) {
return [!disableSpecificWeekDays(date) && !nationalDays(date)];
}
function nationalDays(date) {
var m = date.getMonth(), d = date.getDate(), y = date.getFullYear();
for (i = 0; i < disabledDays.length; i++) {
if ($.inArray((m + 1) + '-' + d + '-' + y, disabledDays) != -1 || new Date() > date) {
return true;
}
}
return false;
}
function disableSpecificWeekDays(date) {
var daysToDisable = blockDays;
var day = date.getDay();
for (i = 0; i < daysToDisable.length; i++) {
if ($.inArray(day, daysToDisable) != -1) {
return [false];
}
}
return [true];
}
});
</script>
If I run ONLY the disableSpecificWeekDays in the "beforeShowDay" parameter it works fine, same goes with the nationalDays. But for some reason it FEELS like it's simply ignoring the date parameter if I call it through the noHoliday function.
In short, I need help!

Just noticed your question after having answered a similar/duplicate question. Instead of copying the code from there just have a look here: Hide weekdays and specific dates of jquery datepicker

Change the day background color in FullCalendar

I'm using FullCalendar in my asp.net application. I need to change the day background color.
What i have tried so far :
dayRender: function (date, cell) {
var today = new Date();
var end = new Date();
end.setDate(today.getDate()+7);
if (date.getDate() === today.getDate()) {
cell.css("background-color", "red");
}
var start = new Date();
start.setDate(today.getDate()+1);
while(start <= end){
//alert(start + "\n" + tomorrow);
if(start.getDate() == date.getDate()){
cell.css("background-color", "yellow");
}
var newDate = start.setDate(start.getDate() + 1);
start = new Date(newDate);
}
}
This change background color of whole days. Demo
But my need is to change the background color of days, 7 days onward from current date.
Example
Today is 2013-July-29. I need to change the background color of below days.
2013-July-30
2013-July-31
2013-August-01
2013-August-02
2013-August-03
2013-August-04
2013-August-05
How can i do this ?

You can do it like this:
dayRender: function (date, cell) {
var today = new Date();
var end = new Date();
end.setDate(today.getDate()+7);
if (date.getDate() === today.getDate()) {
cell.css("background-color", "red");
}
if(date > today && date <= end) {
cell.css("background-color", "yellow");
}
}
http://jsfiddle.net/z8Jfx/7/

dayRender : function(date, cell) {
var idx = null;
var today = new Date().toDateString();
var ddate = date.toDate().toDateString();
if (ddate == today) {
idx = cell.index() + 1;
cell.css("background-color", "azure");
$(
".fc-time-grid .fc-bg table tbody tr td:nth-child("
+ idx + ")").css(
"background-color", "azure");
}
}
