jQuery's datepicker not showing up after validation error [duplicate]

I have dynamically created textboxes, and I want each of them to be able to display a calendar on click. The code I am using is:
$(".datepicker_recurring_start" ).datepicker();
Which will only work on the first textbox, even though all my textboxes have a class called datepicker_recurring_start.
Your help is much appreciated!

here is the trick:
$('body').on('focus',".datepicker_recurring_start", function(){
$(this).datepicker();
});​
DEMO
The $('...selector..').on('..event..', '...another-selector...', ...callback...); syntax means:
Add a listener to ...selector.. (the body in our example) for the event ..event.. ('focus' in our example). For all the descendants of the matching nodes that matches the selector ...another-selector... (.datepicker_recurring_start in our example) , apply the event handler ...callback... (the inline function in our example)
See http://api.jquery.com/on/ and especially the section about "delegated events"

For me below jquery worked:
changing "body" to document
$(document).on('focus',".datepicker_recurring_start", function(){
$(this).datepicker();
});

Note: make sure your id is different for each field

This is just updated to check for hasDatepicker class.
$('body').on('focus',".datepicker", function(){
if( $(this).hasClass('hasDatepicker') === false ) {
$(this).datepicker();
}
});

Make sure your element with the .date-picker class does NOT already have a hasDatepicker class. If it does, even an attempt to re-initialize with $myDatepicker.datepicker(); will fail! Instead you need to do...
$myDatepicker.removeClass('hasDatepicker').datepicker();

You need to run the .datepicker(); again after you've dynamically created the other textbox elements.
I would recommend doing so in the callback method of the call that is adding the elements to the DOM.
So lets say you're using the JQuery Load method to pull the elements from a source and load them into the DOM, you would do something like this:
$('#id_of_div_youre_dynamically_adding_to').load('ajax/get_textbox', function() {
$(".datepicker_recurring_start" ).datepicker();
});

This was what worked for me (using jquery datepicker):
$('body').on('focus', '.datepicker', function() {
$(this).removeClass('hasDatepicker').datepicker();
});

The new method for dynamic elements is MutationsObserver .. The following example uses underscore.js to use ( _.each ) function.
MutationObserver = window.MutationObserver || window.WebKitMutationObserver || window.MozMutationObserver;
var observerjQueryPlugins = new MutationObserver(function (repeaterWrapper) {
_.each(repeaterWrapper, function (repeaterItem, index) {
var jq_nodes = $(repeaterItem.addedNodes);
jq_nodes.each(function () {
// Date Picker
$(this).parents('.current-repeateritem-container').find('.element-datepicker').datepicker({
dateFormat: "dd MM, yy",
showAnim: "slideDown",
changeMonth: true,
numberOfMonths: 1
});
});
});
});
observerjQueryPlugins.observe(document, {
childList: true,
subtree: true,
attributes: false,
characterData: false
});

$('body').on('focus',".my_date_picker", function(){
$(this).datepicker({
minDate: new Date(),
});
});

None of the other solutions worked for me. In my app, I'm adding the date range elements to the document using jquery and then applying datepicker to them. So none of the event solutions worked for some reason.
This is what finally worked:
$(document).on('changeDate',"#elementid", function(){
alert('event fired');
});
Hope this helps someone because this set me back a bit.

you can add the class .datepicker in a javascript function, to be able to dynamically change the input type
$("#ddlDefault").addClass("datepicker");
$(".datepicker").datetimepicker({ timepicker: false, format: 'd/m/Y', });

I have modified #skafandri answer to avoid re-apply the datepicker constructor to all inputs with .datepicker_recurring_start class.
Here's the HTML:
<div id="content"></div>
<button id="cmd">add a datepicker</button>
Here's the JS:
$('#cmd').click(function() {
var new_datepicker = $('<input type="text">').datepicker();
$('#content').append('<br>a datepicker ').append(new_datepicker);
});
here's a working demo

This is what worked for me on JQuery 1.3 and is showing on the first click/focus
function vincularDatePickers() {
$('.mostrar_calendario').live('click', function () {
$(this).datepicker({ showButtonPanel: true, changeMonth: true, changeYear: true, showOn: 'focus' }).focus();
});
}
this needs that your input have the class 'mostrar_calendario'
Live is for JQuery 1.3+ for newer versions you need to adapt this to "on"
See more about the difference here http://api.jquery.com/live/

$( ".datepicker_recurring_start" ).each(function(){
$(this).datepicker({
dateFormat:"dd/mm/yy",
yearRange: '2000:2012',
changeYear: true,
changeMonth: true
});
});

Add custom classname to jquery calendar cell

I am using Jquery calendar. I am trying to insert a new class name to each cell of calendar. It gets added but it is getting removed as and when the calendar is clicked.
Basically it refreshes the calendar on every click so newly added class is getting removed on refresh.
How do I retain the class name?
here is my code
$(function() {
$('#custom-date-format').multiDatesPicker({
dateFormat: "y-m-d"
});
$('.ui-state-default').addClass("calendar_bg");
});
Demo

Use callback functions of Datepicker Widget
$('#DatePicker').datepicker({
//The calendar is recreated OnSelect for inline calendar
onSelect: function (date, dp) {
updateDatePickerCells();
},
onChangeMonthYear: function(month, year, dp) {
updateDatePickerCells();
},
beforeShow: function(elem, dp) { //This is for non-inline datepicker
updateDatePickerCells();
}
});
updateDatePickerCells();
function updateDatePickerCells(dp) {
/* Wait until current callstack is finished so the datepicker
is fully rendered before attempting to modify contents */
setTimeout(function () {
$('.ui-datepicker td > *').each(function (idx, elem) {
$(this).addClass("calendar_bg");
});
}, 0);
}
See Demo
For multiDatesPicker()
$(function() {
$('#from-input').multiDatesPicker({
beforeShow: function(elem, dp) {
updateDatePickerCells();
}
});
});

Why don't you suppose to override the existing .ut-state-default background-color instead of going for adding new one?
.ui-state-default{background: #ffeb3b !important}

It's a known tricky jQuery UI calendar issue, see this question jQuery ui - datepicker prevent refresh onSelect
Anyway, the fix is to add inst.inline = false; on select, like this
$('#custom-date-format').multiDatesPicker({
dateFormat: "y-m-d",
onSelect: function(date, inst){
inst.inline = false;
$('.ui-state-default').addClass("calendar_bg");
}
});
See a demo, note however, that it throws an error in multidatespicker.js. There seems to be an issue with this plugin.

It would be better to use the existing class name and override its default styling.
Add this style .ui-widget-content a.ui-state-default { background: #ffeb3b }
Here is the same demo

Focus is coming on validate datepicker field in jquery

Focus is coming on validate datepicker field in jquery and it showing me opening calendar. I want only validate message not popup of datepicker.

A quick hack from your method:
$.validator.addMethod("endDate", function(value, element) {
var startDate = $('#txt_reg_form').val(),
ret = Date.parse(startDate) <= Date.parse(value) || value == "";
if(!ret){ /*IF NOT VALID DATE*/
/*TRY DISABLING DATEPICKER FOR A MOMENT*/
$("#txt_reg_form").datepicker('disable');
/*SET TIMEOUT TO ENABLE IT AFTER 1 SECOND*/
setTimeout(function(){
$("#txt_reg_form").datepicker('enable');
}, 1000);
}
return ret;
}
, "To date should be greater then From date"
);
If a datepicker is associated with a field, it will popup calender on focusing on the field. You can change the default behaviour of showing popup on focus to show it on clicking button/icon by following code:
$( "#datepicker" ).datepicker({
showOn: "button",
buttonImage: "images/calendar.gif",
buttonImageOnly: true
});

How to unfocus the user from the input box in a confirmation box using Jquery?

I am having a confirmation box with a input field requesting a date. When the confirmation box appears, the input box is in focus. How do I unfocus it? I need to drop down a calendar when I click on the input field. Here is my relevant code:
$(".confirmLink").click(function(e) {
e.preventDefault();
var targetUrl = $(this).attr("href");
document.getElementById('dialog').focus();
$("#dialog").dialog({
buttons : {
"OK" : function() {
window.location.href = targetUrl+"/"+"deletedDate"+"/"+document.getElementById('deletedDate').value;
},
"Cancel" : function() {
$(this).dialog("close");
}
}
});
$("#dialog").dialog("open");
});
function datepicker(){
$( "#deletedDate" ).datepicker(
{
dateFormat: 'yy-mm-dd',
changeMonth: true,
changeYear: true,
showAnim: "slideDown"
});
}

This should do the trick:
.blur();
(as was pointed out - this is sufficient)

You can also trigger blur as an event
document.getElementById('dialog').blur();
Or
$('#dialog').blur();

Use blur() event.
document.getElementById("dialog").blur();
