putting datepicker() on dynamically created elements - JQuery/JQueryUI

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();
});

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
});

This was what worked for me (using jquery datepicker):

$('body').on('focus', '.datepicker', function() {
 $(this).removeClass('hasDatepicker').datepicker();
});

 $('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
	});
});
