Question

I want to prevent a user from choosing previous dates thus disable previous dates in my datepicker. I am using bootstrap-datepicker from http://www.eyecon.ro/bootstrap-datepicker .

I called the javascript like so

<script>
$(function() {
    $( ".mydatepicker" ).datepicker({
       format:'yyyy/mm/dd'
    });
});
</script>

The validation of the date is not supported (as of now) but the plugin provides events that you can listen to : in this case, the changeDate event.

var minDate = new Date(); // Our minimum

$('.someSelector').datepicker()
.on('changeDate', function(ev){
    if (ev.date.valueOf() < minDate.valueOf()){

        /* Handle previous date */
        alert('Nope');
        // and eventually reset the date

        /* And this for later versions (just in case) */
        ev.preventDefault();
        return false;
    }
});

Here is a demo (jsfiddle) with a working example.
