Highlight dates in specific range with jQuery's datepicker

Question

I need to highlight the dates between a start date and an end date, which I should be able to specify. Can anyone help me?

Answer 1

You can use the beforeShowDay event. It will get called for each date that needs to be shown in the calendar. It passes in a date and return an array with [0]= isSelectable, [1]= cssClass, [2]=Some tooltip text

$('#whatever').datepicker({
            beforeShowDay: function(date) {
             if (date == myDate) {
              return [true, 'css-class-to-highlight', 'tooltipText'];
              }else{
              //this will allow the cell be selected without been highlighted
              return [true,'']
              }
           }
});

Here's a working example! You will nees to make a package from here with http://jqueryui.com/download with core, widget and datepicker.

The javascript part to put before :

<script>
$(document).ready(function() {

    var dates = ['22/01/2012', '23/01/2012']; //
            //tips are optional but good to have
    var tips  = ['some description','some other description'];      

    $('#datepicker').datepicker({                
        dateFormat: 'dd/mm/yy',
        beforeShowDay: highlightDays,
        showOtherMonths: true,
        numberOfMonths: 3,
    });

    function highlightDays(date) {
        for (var i = 0; i < dates.length; i++) {
            if (new Date(dates[i]).toString() == date.toString()) {              
                return [true, 'highlight', tips[i]];
            }
        }
        return [true, ''];
     } 

});
</script>

The HTML part:

<div id="datepicker"></div>

Add somewhere this CSS:

    td.highlight {border: none !important;padding: 1px 0 1px 1px !important;background: none !important;overflow:hidden;}
td.highlight a {background: #99dd73 url(bg.png) 50% 50% repeat-x !important;  border: 1px #88a276 solid !important;}

And you will need to make a small image called bg.png to make it work

Thought I would throw in my two cents as it seems faster and more light weight than others:

jQuery(function($) {
  var dates = {
    '2012/6/4': 'some description',
    '2012/6/6': 'some other description'
  };

  $('#datepicker').datepicker({
    beforeShowDay: function(date) {
      var search = date.getFullYear() + '/' + (date.getMonth() + 1) + '/' + date.getDate();

      if (search in dates) {
        return [true, 'highlight', (dates[search] || '')];
      }

      return [false, '', ''];
    }
  });
});

Not sure if this will be still useful, but as this was useful to me, I want to share what I did:

In my JavaScript:

var holidays= ["2016/09/18", "2016/09/19", "2016/01/01", "2016/05/01", "2016/06/27", "2016/08/15"];

$("#SomeID").datepicker({ beforeShowDay: highLight });

function highLight(date) {
        for (var i = 0; i < holidays.length; i++) {
            if (new Date(holidays[i]).toString() == date.toString()) {
                return [true, 'ui-state-holiday'];
            }
        }
        return [true];
    }

And in the jquery-ui-theme.css I've added

.ui-state-holiday .ui-state-default {
    color: red;
}

If you want to highlight weekends also, you have to use this CSS instead

.ui-state-holiday .ui-state-default, .ui-datepicker-week-end .ui-state-default {
    color: red;
}

And this is the result:

(Note that I have configured my language to spanish, but this is not important to this code)

If you are using Keith Wood's datepick you can use the following example taken from here

$(selector).datepick({onDate: highlightDays}); 

function highlightDays(date) { 
    return {selectable: true, dateClass: 'highlight-custom', title: 'tooltip'}; 
}

Late to the party, but here's a JSFiddle that I used to test:

https://jsfiddle.net/gq6kdoc9/

HTML:

  <div id="datepicker"></div>

JavaScript:

var dates = ['11/13/2017', '11/14/2017'];
   //tips are optional but good to have
   var tips = ['some description', 'some other description'];

   $('#datepicker').datepicker({
     dateFormat: 'dd/mm/yy',
     beforeShowDay: highlightDays,
     showOtherMonths: true,
     numberOfMonths: 3,
   });

   function highlightDays(date) {
     for (var i = 0; i < dates.length; i++) {
       if (new Date(dates[i]).toString() == date.toString()) {
         return [true, 'highlight', tips[i]];
       }
     }
     return [true, ''];
   }

And CSS:

td.highlight {
  border: none !important;
  padding: 1px 0 1px 1px !important;
  background: none !important;
  overflow: hidden;
}

td.highlight a {
  background: #ad3f29 url(bg.png) 50% 50% repeat-x !important;
  border: 1px #88a276 solid !important;
}

Built on Mike's working example above!

mugur, your code didn't quite work for me in Firefox or Safari, it required the date var to be formatted (which I got from here). Here

function highlightDays(date) {
for (var i = 0; i < dates.length; i++) {

var d = date.getDate();
var m =  date.getMonth();
m += 1;  // JavaScript months are 0-11
var y = date.getFullYear();

var dateToCheck = (d + "/" + m + "/" + y);
    if (dates[i] == dateToCheck) {
        return [true, 'highlight', tips[i]];
    }
    }
return [true, ''];
}

And, of course, as the above function stands it doesn't account for leading-zeroes padding so the dates array needed to be changed to:

var dates = ['22/1/2014', '23/1/2014'];
