[javascript] How to restrict the selectable date ranges in Bootstrap Datepicker?

I need to use datepicker which provides me the option of restricting the selectable dates. We had been using jQuery UI which is used to support it using minDate, maxDate options.

$("#id_date").datepicker({minDate: +1, maxDate: '+1M +10D'}); 

Recently we started using Twitter Bootstrap for our styles. And apparently, Twitter Bootstrap is incompatible with jQuery UI styles. So I tried using one of the bootstrap compatible datepickers available at http://www.eyecon.ro/bootstrap-datepicker/.

Unfortunately, the above plugin is not as configurable as jQuery UI's datepicker. Can anyone help me out with restricting the selectable date ranges in the new datepicker.

With selectable date ranges you might want to use something like this. My solution prevents selecting #from_date bigger than #to_date and changes #to_date startDate every time when user selects new date in #from_date box:

JS file:

var startDate = new Date('01/01/2012');
var FromEndDate = new Date();
var ToEndDate = new Date();

ToEndDate.setDate(ToEndDate.getDate()+365);

$('.from_date').datepicker({

    weekStart: 1,
    startDate: '01/01/2012',
    endDate: FromEndDate, 
    autoclose: true
})
    .on('changeDate', function(selected){
        startDate = new Date(selected.date.valueOf());
        startDate.setDate(startDate.getDate(new Date(selected.date.valueOf())));
        $('.to_date').datepicker('setStartDate', startDate);
    }); 
$('.to_date')
    .datepicker({

        weekStart: 1,
        startDate: startDate,
        endDate: ToEndDate,
        autoclose: true
    })
    .on('changeDate', function(selected){
        FromEndDate = new Date(selected.date.valueOf());
        FromEndDate.setDate(FromEndDate.getDate(new Date(selected.date.valueOf())));
        $('.from_date').datepicker('setEndDate', FromEndDate);
    });

HTML:

<input class="from_date" placeholder="Select start date" contenteditable="false" type="text">
<input class="to_date" placeholder="Select end date" contenteditable="false" type="text" 

And do not forget to include bootstrap datepicker.js and .css files aswell.

Another possibility is to use the options with data attributes, like this(minimum date 1 week before):

<input class='datepicker' data-date-start-date="-1w">

The example above can be simplify a bit. Additionally you can put date manually from keyboard instead of selecting it via datepicker only. When clearing the value you need to handle also 'on clearDate' action to remove startDate/endDate boundary:

JS file:

$(".from_date").datepicker({
    format: 'yyyy-mm-dd',
    autoclose: true,
}).on('changeDate', function (selected) {
    var startDate = new Date(selected.date.valueOf());
    $('.to_date').datepicker('setStartDate', startDate);
}).on('clearDate', function (selected) {
    $('.to_date').datepicker('setStartDate', null);
});

$(".to_date").datepicker({
    format: 'yyyy-mm-dd',
    autoclose: true,
}).on('changeDate', function (selected) {
    var endDate = new Date(selected.date.valueOf());
    $('.from_date').datepicker('setEndDate', endDate);
}).on('clearDate', function (selected) {
    $('.from_date').datepicker('setEndDate', null);
});

HTML:

<input class="from_date" placeholder="Select start date" type="text" name="from_date">
<input class="to_date" placeholder="Select end date" type="text" name="to_date">

Most answers and explanations are not to explain what is a valid string of endDate or startDate. Danny gave us two useful example.

$('#datepicker').datepicker({
    startDate: '-2m',
    endDate: '+2d'
});

But why?let's take a look at the source code at bootstrap-datetimepicker.js. There are some code begin line 1343 tell us how does it work.

if (/^[-+]\d+[dmwy]([\s,]+[-+]\d+[dmwy])*$/.test(date)) {
            var part_re = /([-+]\d+)([dmwy])/,
                parts = date.match(/([-+]\d+)([dmwy])/g),
                part, dir;
            date = new Date();
            for (var i = 0; i < parts.length; i++) {
                part = part_re.exec(parts[i]);
                dir = parseInt(part[1]);
                switch (part[2]) {
                    case 'd':
                        date.setUTCDate(date.getUTCDate() + dir);
                        break;
                    case 'm':
                        date = Datetimepicker.prototype.moveMonth.call(Datetimepicker.prototype, date, dir);
                        break;
                    case 'w':
                        date.setUTCDate(date.getUTCDate() + dir * 7);
                        break;
                    case 'y':
                        date = Datetimepicker.prototype.moveYear.call(Datetimepicker.prototype, date, dir);
                        break;
                }
            }
            return UTCDate(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds(), 0);
        }

There are four kinds of expressions.

• w means week
• m means month
• y means year
• d means day

Look at the regular expression ^[-+]\d+[dmwy]([\s,]+[-+]\d+[dmwy])*$. You can do more than these -0d or +1m.

Try harder like startDate:'+1y,-2m,+0d,-1w'.And the separator , could be one of [\f\n\r\t\v,]

i am using v3.1.3 and i had to use data('DateTimePicker') like this

var fromE = $( "#" + fromInput );
var toE = $( "#" + toInput );
$('.form-datepicker').datetimepicker(dtOpts);

$('.form-datepicker').on('change', function(e){
   var isTo = $(this).attr('name') === 'to';

   $( "#" + ( isTo ? fromInput : toInput  ) )
      .data('DateTimePicker')[ isTo ? 'setMaxDate' : 'setMinDate' ](moment($(this).val(), 'DD/MM/YYYY'))
});
