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
I am using the jquery ui datepicker but I want to show the week number only if the input element has a specific class...
Here's what I've tried but with no success...
$(".myCal").datepicker({
showWeek: function(dateText, inst) { $(this).hasClass("showWeek"); }
});
As class selector is used, each method is required to iterate over all matching elements and then use $(this).
$(".myCal").each(function () {
$(this).datepicker({
showWeek: $(this).hasClass('showWeek')
});
});
http://jsfiddle.net/Ubw3L/5/
Can you try this
$(".myCal").datepicker({
showWeek: $(this).hasClass("showWeek");
});
As the API states, showWeek accept boolean value.
$('.myCal').each(function () {
$(this).datepicker({
showWeek: $(this).hasClass('showWeek');
});
});
I´m trying to call two functions when closing the jQuery UI Datepicker, but I´m not sure what´s the best way to do this.
If I only have one function I can do this:
function splitArrivalDate() {
// Some code
}
$( '#mydatepicker' ).datepicker({
onClose: splitArrivalDate
});
But what if I want to call two functions sequentially on the onClose event?
function splitArrivalDate() {
// Some code
}
function setDepartureDate() {
// Some code
}
$( '#mydatepicker' ).datepicker({
onClose: splitArrivalDate; setDepartureDate // Does not work
});
I hope someone can help me understand this. Thanks!
You want something like this:
$( '#mydatepicker' ).datepicker({
onClose: function () { splitArrivalDate(); setDepartureDate(); }
});
I have code which the user choose date .
I need to to get the value year and put it in div.
How can I do that?
jsFissl Demo
many Thx.
the code:
<div class="demo">
<p>Date: <input type="text" id="datepicker"></p>
</div>
<div id="Year"></div>
$("#datepicker").datepicker({
changeMonth: true,
changeYear: true
});
$("#Year").text($("#datepicker").val());
I try to use .substring(0, 4)but I don't kno how.
You can convert that input value into a Javascript Date as well and have everything from it's method.
http://jsbin.com/ugaxob/2/edit
$(".btn-getdate").click(function() {
var dt = $("#datepicker").val(),
d = new Date(dt);
$("#Year").text(d.getFullYear());
});
or go wild and use MomentJs plugin and you will get so much fun (live example updated)
When you want to perform something on a plugin, that is called act upon an event, and you should see the Events tab in the DatePicker, where you can find onSelect.
My live example was changed to act upon selection and no need to press any link or button.
This shows the year you wanted to extract.
HTML:
<meta charset="utf-8">
<div class="demo">
<p>Date: <input type="text" id="datepicker"></p>
<button>Show year</button>
</div><!-- End demo -->
JS:
$(function() {
$("#datepicker").datepicker({
changeMonth: true,
changeYear: true
});
$("button").click(function() {
var split = $("#datepicker").val().split('/');
alert(split[2]);
});
});
The split method of String class divides the string and returns as an array.
EDIT: This does everything you wanted.
Take a look at the onSelect event.
$(function() {
$("#datepicker").datepicker({
changeMonth: true,
changeYear: true,
onSelect: function(dateText) {
var split = $("#datepicker").val().split('/');
$("#Year").text(split[2]);
}
});
});
How about this : JSFiddle
No need to do string manipulation, just create Date object using selected date from datepicker and use getFullYear() method to get selected year...
$(function() {
$("#datepicker").datepicker({
onSelect: function(date) {
var d = new Date(date);
alert(d.getFullYear());
},
changeMonth: true,
changeYear: true
});
});
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();
});
Thanks to skafandri
Note: make sure your id is different for each field
Excellent answer by skafandri +1
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
});
});
