[jquery] Open JQuery Datepicker by clicking on an image w/ no input field

I want to have the JQuery Datepicker open when the user clicks on an image. There is no input field where the selected date appears afterwards; I'm just going to save the entered date to the server via Ajax.

Currently I have this code:

<img src='someimage.gif' id="datepicker" />

$(document).ready(function() {
    $("#datepicker").datepicker({
            changeMonth: true,
            changeYear: true,
        }).click(function() { $(this).datepicker('show'); });
 });

But nothing happens when I click on the image. I have also tried saving the result of the datepicker() call to a global var and then calling datepicker('show') from the onclick() event of the image, but same result.

HTML:

<div class="CalendarBlock">
    <input type="hidden">
</div>

CODE:

$CalendarBlock=$('.CalendarBlock');
$CalendarBlock.click(function(){
    var $datepicker=$(this).find('input');
    datepicker.datepicker({dateFormat: 'mm/dd/yy'});
    $datepicker.focus(); });

To change the "..." when the mouse hovers over the calendar icon, You need to add the following in the datepicker options:

    showOn: 'button',
    buttonText: 'Click to show the calendar',
    buttonImageOnly: true, 
    buttonImage: 'images/cal2.png',

$(function() {
   $("#datepicker").datepicker({
       //showOn: both - datepicker will come clicking the input box as well as the calendar icon
       //showOn: button - datepicker will come only clicking the calendar icon
       showOn: 'button',
      //you can use your local path also eg. buttonImage: 'images/x_office_calendar.png'
      buttonImage: 'http://theonlytutorials.com/demo/x_office_calendar.png',
      buttonImageOnly: true,
      changeMonth: true,
      changeYear: true,
      showAnim: 'slideDown',
      duration: 'fast',
      dateFormat: 'dd-mm-yy'
  });
});

The above code belongs to this link

The jQuery documentation says that the datePicker needs to be attached to a SPAN or a DIV when it is not associated with an input box. You could do something like this:

<img src='someimage.gif' id="datepickerImage" />
<div id="datepicker"></div>

<script type="text/javascript">
 $(document).ready(function() {
    $("#datepicker").datepicker({
            changeMonth: true,
            changeYear: true,
    })
    .hide()
    .click(function() {
      $(this).hide();
    });

    $("#datepickerImage").click(function() {
       $("#datepicker").show(); 
    });
 });
</script>

Having a hidden input field leads to problems with datepicker dialog positioning (dialog is horizontally centered). You could alter the dialog's margin, but there's a better way.

Just create an input field and "hide" it by setting it's opacity to 0 and making it 1px wide. Also position it near (or under) the button, or where ever you want the datepicker to appear.

Then attach the datepicker to the "hidden" input field and show it when user presses the button.

HTML:

<button id="date-button">Show Calendar</button>
<input type="text" name="date-field" id="date-field" value="">

CSS:

#date-button {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 2;
    height 30px;
}

#date-field {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 1;
    width: 1px;
    height: 32px; // height of the button + a little margin
    opacity: 0;
}

JS:

$(function() {
   $('#date-field').datepicker();

   $('#date-button').on('click', function() {
      $('#date-field').datepicker('show');
   });
});

Note: not tested with all browsers.

<img src='someimage.gif' id="datepicker" />
<input type="hidden" id="dp" />

 $(document).on("click", "#datepicker", function () {
   $("#dp").datepicker({
    dateFormat: 'dd-mm-yy',
    minDate: 'today'}).datepicker( "show" ); 
  });

you just add this code for image clicking or any other html tag clicking event. This is done by initiate the datepicker function when we click the trigger.

If you are using an input field and an icon (like this example):

<input name="hasta" id="Hasta"  type="text" readonly  />
<a href="#" id="Hasta_icono" ></a>

You can attach the datepicker to your icon (in my case inside the A tag via CSS) like this:

$("#Hasta").datepicker();
  $("#Hasta_icono").click(function() { 
   $("#Hasta").datepicker( "show" );
  });
