The strings can't find value of window.* , you should try another way to translate strings.

Javascript Datepicker - Selecting date which links to time

Please be aware that I am a total noob at JS, sorry if I don't understand basic coding language. Solutions are very welcome. Thanks!
I have created my own form and have two input fields which consist of 'date of incident' and 'time of incident'. The user will need to select a date either the current date or previous dates only. Then the user will select a time and if the user selected the current date it can only be before the current time. Otherwise anytime is ok.
I have already developed the datepicker for 'date of incident' but I need all the dates after the current date to be grayed out, im not sure if I will need to use 'minDate' or 'maxDate' for this and if I will need to implement it to a existing function or create a new one.
For the 'time of incident' I am using 'type="time".
I have got a little bit of an idea for the date of incident:
futureDates = dates after current date
currentDate = today
futureDates = greyed out
But I am starting out with JavaScript and don't really know how to implement it properly into the code.
HTML:
<input id="datepick" placeholder="Enter the date of incident" type="text"/>
<input id="timepick" placeholder="Enter the time of incident" type="time"/>
Javascript for Datepicker:
var datepickr = (function() {

Sorry I don't have any code for my 'Time of Incident' field but I have a small psuedocode that I would like to turn into JavaScript and implement it into my code:
currentDate = new Date()
currentTime = new Date(time)
function timeSelect{
if{
datepicker = currentDate
{
time = currentTime (Can't select time past now, greyed out)
else
{
any time can be selected
}
Thank you for your time, it really helps me out.

How to allow datepicker to pick future dates in JQuery?

I need a datepicker for our project and whilst looking online.. I found one. However, it disables to allow future dates. I tried looking into the code but I cannot fully understand it. I'm kind of new to JQuery.
This is the code (it's very long, sorry):
<script>

$.datepicker._defaults.onAfterUpdate = null;
$.datepicker._defaults.base_update = $.datepicker._updateDatepicker;
$.datepicker._defaults.base_generate = $.datepicker._generateHTML;

There is a comment along the code that says, "Allow Future Dates?" That's where I tried looking but I had no luck for hours now. Please help me.
This is how the date range picker looks like in my page:
Thank you so much for your help.
UPDATE: JSFIDDLE http://jsfiddle.net/dacrazycoder/4Fppd/

In cfg, add a property with key allowFuture with the value of true

Destroy Javascript Datepicker Onblur

I have a javascript datepicker which works perfectly, with one exception. If the user tabs out of the form field without selecting a date, the datepicker remains on the screen. I need to destroy onBlur but not sure where.
The function calling the date picker in the body is:
<script type="text/javascript" src="../Datepicker/datepickr.js"></script>
<script type="text/javascript">
new datepickr('effectiveDate', {
'dateFormat': 'n/j/Y'

document.getElementById('effectiveDate').addEventListener('blur', function (e) {
d.close();

How to pull selected date value from jsCalendar

The code you posted turns any div with a class of jsCalendar into a jsCalendar.
You're going to want to assign an individual id to any jsCalendar object you want to access the dates of.
You should be able to see what 2 dates the user has selected by calling the data function on the jsCalendar object. For instance, if you had a jsCalendar with an id of jsCalendar1:
var startDate = $("#jsCalendar1").data("startdate");
var endDate = $("#jsCalendar1").data("enddate");
alert("Calendar 1 has a start date of " + startDate + " and an end date of " + endDate + ".");
Make sure you put this code somewhere appropriate, such as in a function that isn't called until after a user has selected a start and end date.
Here's a working jsFiddle.
