I have developed a custom Web Part on SharePoint 2013.
I'm using the default date picker control. I also have an array with all the holidays in Italy, and I would like to "validate" the selected date just after the user clicks on the datetimepicker. Validate in my case should be print an alert message if the selected date is a holiday.
I've tried this code, but it is not firing:
$(".ms-picker-table a").on("click",function() {
console.log("ON CLICK DATEPICKER");
/* DATES CHECK */
[...]
});
ms-picker-table is the class of the date picker control.
a elements inside this table already contain code in href attribute:
javascript:ClickDay('01\u002f06\u002f2017')
I don't know if it can create problems.
Also parent td element of each link has this code:
onclick="javascript:ClickDay('01\u002f06\u002f2017')"
So is there a way to correct my code to check dates when a user select a value from datepicker?
onBlur event should do the job
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="date" id="dateField">
<script>
$("input[id*='dateField']").blur(function(){
var dateValue=$("input[id='dateField']").val();
console.log(dateValue);
// check array to see if the date is in the Array
});
</script>

I use the jquery datepicker in an Angular Application and I noticed a behavior that I would like to prevent.
The application consists of an input field for the date and a select box for a month selection.
If the months in the select box are changed, the minDate of the jquery date picker should be adjusted.
I tried the following example:
I set the date in the input field to the 24.04.2018
I chose October
The date of the input field is automatically set to 24.10.2018
I do not want the content of the Inputs field to be automatically adjusted.
Here is my git-hub project: https://github.com/annalen/jquery-datepicker
Many thanks for the help
Solution
I use the beforeShow and onClose date-picker functions
jQuery(yourElement).datepicker('option', 'beforeShow', function (date) {
return {
'minDate': yourMinDate,
'maxDate': yourMaxDate
};
});
jQuery(yourElement).datepicker('option', 'onClose', function (date) {
jQuery(this).datepicker('option', {
'minDate': null,
'maxDate': null
});
});
The datepicker updates the date only if the selected one is out of the range.
For example, if the current selected date is 24.04.2018 and you set the minDate to 20.04.2018, nothing will happen.
But if you set it to any date after 24.04.2018, it will get updated. I believe it's normal since its the purpose of setting a minDate.
You can always set yourself manually the input's value: $('#datepicker').val('20.04.2018') but I don't think it's a good idea to have something displayed different than the internal datepicker component state (the calendar that will popup will show a different date than the one in the input)

The jquery datepicker defaultdate will not automatically set to next available date when the graphical calendar is persistent on a page. the initial date the calendar selects can be a date that i have disabled. Many suggestions on workaround work when the calendar is a popup to an input field, but do not work when the calendar is persistently shown as a div. doesn't matter if the dates disabled are by noWeekends, by the day of week, or individually set days, the initial date value can be a disabled and unclickable date. I am using the alternate1 input field (which i normally hide) to pass data onto a PHP page. What i have almost works, but the next available date shows as highlighted when minDate happens to land on an available date, but when minDate lands on an unselectible date, the highlight is hidden. The temporary fix i used of setDate null - clears the initial selection value regardless of the highlight, so a visitor may think the a date is already selected when it is not. My PHP page reports back to the visitor that they have to go back and actually select a date. My use of datepicker is geared toward mobile, so popup or flyout calendar to make use of well known workarounds is unfavorable, the calendar GUI needs to be persistent on the page. To recreate my issue for yourself, on the jsfiddle, comment out the last javascript line, disallow a date mid-week in the var selections, and then set the minDate so that it will land on the disallowed date. you'll notice the alternate1 input gets prefilled with the disallowed date.
html code:
<div id="dp1"></div>
<input type="text" id="alternate1" name="alternate1"/> <!-- style="display:none;" this is the field that passes on to php -->
javascript code:
var selections = [
"2017-07-29",
"2017-07-30",
"2017-08-05",
"2017-08-06",
"2017-08-12",
"2017-08-13",
"2017-08-19",
"2017-08-20",
"2017-08-26",
"2017-08-27",
"2017-09-02",
"2017-09-03",
"2017-09-04",
"2017-09-09",
"2017-09-10",
"2017-09-16",
"2017-09-17",
"2017-09-23",
"2017-09-24",
"2017-09-30",
"2017-10-01",
"2017-10-07",
"2017-10-08",
"2017-10-09",
"2017-10-14",
]
function bansingle(date) {
var excerpt = jQuery.datepicker.formatDate('yy-mm-dd', date);
return [ selections.indexOf(excerpt) == -1 ]
}
// somehow combine this function later.
//function bandow(date) {
// var day = date.getDay();
// return [(day != 0 && day != 6)];
// }
$('#dp1').datepicker({
beforeShowDay: bansingle,
altField:'#alternate1',
altFormat: 'm-d-yy',
fielddateFormat: 'm-d-yy',
minDate: "+0d",
//maxDate: "+1m", // set latest selectable date
});
$('#dp1').datepicker("setDate", null); //clears alternate1 input field value
Here is the jsfiddle it does contain more dates and a little CSS. I recommend opening it in a new tab, to be able to return to this page after editing code.
the progress of my other question here has negated the need for an answer to this question. pursuing multiple changes to input, styling, and options - will workaround this question's problem.
Explanation:
I am building a plugin for an application that uses thisa Bootstrap Datepicker plugin here http://www.eyecon.ro/bootstrap-datepicker/
So I am trying to utilize the same plugin for a Date Picker in my plugin for the app that already uses that Date Picker library.
My app is a Project Management app that shows Project Tasks in a popup Modal window. IN the Task Modal, there is a Due Date field.
I want to show the Due Date value for a Task when the Modal is opened. When a user clicks on the text for an existing Due Date field, I want to reveal and show an inline Date Picker Calendar. Just like the linked to library above!
So a user clicks on the Due date to reveal the date picker. They then click a date value which make an AJAX post to server and saves the new date value. It then should update the text that they originally clicked on with the new date value and then hide/close the date picker.
All pretty simple however I can use a little help please!
I have a Working JSFiddle Demo: http://jsfiddle.net/jasondavis/dd1bmrrc/
My custom code is all shown below as well. All that is missing is the Bootstrap Date Picker library, jQuery, MockAjax library, and CSS. It is all loaded on the JSFiddle linked above though.
You can also see some options on the Date Pickers project page here http://www.eyecon.ro/bootstrap-datepicker/
The Problem
On my demo page here http://jsfiddle.net/jasondavis/dd1bmrrc/ you will see that I have a span holding a Date value.
Next to it is a text input which when clicked on shows the Date Picker Calendar.
After selecting a Date, my span is updated and Date Picker is hidden.
Clicking my span again shows the Date picker text box.
You then have to click the text box as well to see the Date Picker Calendar.
So my goal is to not have the Text Box. The Span value should open and close the Datepicker, without a textbox needing to exist!
Is this even possible?
The Code
HTML:
<span id="due-date-span">1/1/2015</span>
<input type="text" class="span2" value="02-16-2012" id="task-due-date-cal">
JavaScript for Date Picker:
$(function(){
// Show Date Picker Calaendar when "Due Date" SPAN text is clicked on:
$('#due-date-span').on('click', function(){
$('#task-due-date-cal').show();
});
// Instantiate and run Date Picker Calendar plugin
var dueDatePicker = $('#task-due-date-cal').datepicker({
format: 'mm-dd-yyyy',
// When Date Picker Date is clicked on to change a Date value:
}).on('changeDate', function(ev){
dueDate = new Date(ev.date);
// Make AJAX POST to save Due Date value to the server and update DOM.
$.ajax
({
type: "post",
url: "updateDueDate",
data: "date="+dueDate,
success: function(result)
{
// UPDATE SPAN #due-date-span with new Date value
$('#due-date-span').text(dueDate);
// Close/Hide Date Picker, until it is clicked to show again
$('#task-due-date-cal').hide();
$('#task-due-date-cal').datepicker('hide');
}
});
});
});
Mock AJAX request for Demo:
// Mock AJAX response for AJAX request to /updateDueDate to Update In-line Task Due Date Fields
$.mockjax({
url: '/updateDueDate',
responseTime: 900, // simulate lag
response: function(settings) {
//console.log(settings.data);
console.log('info', 'UPDATE TASK FIELD AJAX REQUEST SENT', settings.data);
if(settings.data.value == 'err') {
this.status = 500;
this.responseText = 'Validation error!';
} else {
this.responseText = '';
}
}
});
One way is to leave the input, lay it over top of the span but with css that makes it invisible to user. The events are still triggered on the input
#task-due-date-cal, #task-due-date-cal:focus{
position:absolute;
z-index:10000;
left:0;
top:0;
background:none;
font-size:0;
border:none;
margin:0;
box-shadow:none;
}
I used an extra wrapper with position relative around the input and span
DEMO
On the website I'm currently working I have a form to add a event. This event needs a date which the user selects using a jQuery datepicker. A date can only have one event. So I want to check the date the user insert in the datepicker. I tried doing this by getting the value after the user has selected the date. The problem is however, the datepickers doesn't update his value right away.
I made a JSFiddle to show the problem. When you pick a date the span updates and shows the value of the datepicker. But as you can see the first time it is blank, and the second time it shows the previous selected date. So the datepickers does not update is value right away. How can I fix this?
I looked trough other similar questions here on stackoverflow but their solutions didn't work for me.
JSFiddle: http://jsfiddle.net/kmsfpgdk/
HTML:
<input type="text" id="datepicker" name="date" />
<span id="data"></span>
JS:
$('#datepicker').datepicker();
$('#datepicker').blur(function () {
var val = $(this).val();
$('#data').text(val);
});
Its better to use built in method onSelect:fn to use:
$('#datepicker').datepicker({
onSelect: function () {
$('#data').text(this.value);
}
});
Fiddle
As per documentation:
onSelect
Called when the datepicker is selected. The function receives the selected date as text and the datepicker instance as parameters. this refers to the associated input field.
change event happens before blur event.
Use .change() instead of .blur()
$('#datepicker').change(function() {
var val = $(this).val();
$('#data').text(val);
});

If Google brought you here because your input does not seem to respond to various JQuery .on( events, most likely it's because you have another element on the same page with the same id.
I am using this date picker.
http://bootstrap-datepicker.readthedocs.org/en/release/
My concern is that I want to enable date picker on some condition.
For example : I have a select box of a country and if country is US, I want to enable date picker otherwise disable it. Disabling the date picker means user can not select date or No date picker should pop-up.
I am selecting date picker by date picker calendar icon not with textbook.
I assume you use jquery and that your country select box is with class "country", then something like this should work for you:
$(document).ready(function(){
$(".country").change(function(e){
var country = $(".country").val(); //get the value of the country select
if (country != "US") { // you probably use some id and not the country name as value
$(".datepicker").datepicker("remove"); // remove the datepicker
}
});
});
