jQuery Date Picker - disable past dates

I am trying to have a date Range select using the UI date picker.

in the from/to field people should not be able to view or select dates previous to the present day.

This is my code:

$(function() {
	var dates = $( "#from, #to" ).datepicker({
		defaultDate: "+1w",
		changeMonth: true,
		numberOfMonths: 1,
		onSelect: function( selectedDate ) {
			var option = this.id == "from" ? "minDate" : "maxDate",
				instance = $( this ).data( "datepicker" ),
				date = $.datepicker.parseDate(
					instance.settings.dateFormat ||
					$.datepicker._defaults.dateFormat,
					selectedDate, instance.settings );
			dates.not( this ).datepicker( "option", option, date );
		}
	});
});

Can some one tell me how to disable dates previous the to the present date.

You must create a new date object and set it as minDate when you initialize the datepickers

<label for="from">From</label> <input type="text" id="from" name="from"/> <label for="to">to</label> <input type="text" id="to" name="to"/>

var dateToday = new Date();
var dates = $("#from, #to").datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 3,
    minDate: dateToday,
    onSelect: function(selectedDate) {
        var option = this.id == "from" ? "minDate" : "maxDate",
            instance = $(this).data("datepicker"),
            date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings);
        dates.not(this).datepicker("option", option, date);
    }
});

Edit - from your comment now it works as expected http://jsfiddle.net/nicolapeluchetti/dAyzq/1/

Declare dateToday variable and use Date() function to set it.. then use that variable to assign to minDate which is parameter of datepicker.

var dateToday = new Date();	
$(function() {
	$( "#datepicker" ).datepicker({
		numberOfMonths: 3,
		showButtonPanel: true,
		minDate: dateToday
	});
});

That's it... Above answer was really helpful... keep it up guys..

$('#datepicker-dep').datepicker({
    minDate: 0
});

minDate:0 works for me.

Use the "minDate" option to restrict the earliest allowed date. The value "0" means today (0 days from today):

    $(document).ready(function () {
        $("#txtdate").datepicker({
            minDate: 0,
            // ...
        });
    });

Docs here: http://api.jqueryui.com/datepicker/#option-minDate

Just to add to this:

If you also need to prevent the user to manually type a date in the past, this is a possible solution. This is what we ended up doing (based on @Nicola Peluchetti's answer)

var dateToday = new Date();

$("#myDatePickerInput").change(function () {
    var updatedDate = $(this).val();
    var instance = $(this).data("datepicker");
    var date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, updatedDate, instance.settings);

    if (date < dateToday) {
        $(this).datepicker("setDate", dateToday);
    }
});

What this does is to change the value to today's date if the user manually types a date in the past.

Live Demo ,try this,

    $('#from').datepicker(
     { 
        minDate: 0,
        beforeShow: function() {
        $(this).datepicker('option', 'maxDate', $('#to').val());
      }
   });
  $('#to').datepicker(
     {
        defaultDate: "+1w",
        beforeShow: function() {
        $(this).datepicker('option', 'minDate', $('#from').val());
        if ($('#from').val() === '') $(this).datepicker('option', 'minDate', 0);                             
     }
   });

This is easy way to do this

$('#datepicker').datepicker('setStartDate', new Date());

also we can disable future days

$('#datepicker').datepicker('setEndDate', new Date());

set startDate attribute of datepicker, it works, below is the working code

$(function(){
$('#datepicker').datepicker({
    startDate: '-0m'
    //endDate: '+2d'
}).on('changeDate', function(ev){
    $('#sDate1').text($('#datepicker').data('date'));
    $('#datepicker').datepicker('hide');
});
})

By setting startDate: new Date()

$('.date-picker').datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 1,
    ...
    startDate: new Date(),
});

just replace your code:

old code:

$("#dateSelect").datepicker({
	showOtherMonths: true,
	selectOtherMonths: true,
	changeMonth: true,
	changeYear: true,
	showButtonPanel: true,
	dateFormat: 'yy-mm-dd'
	
});

new code:

$("#dateSelect").datepicker({
	showOtherMonths: true,
	selectOtherMonths: true,
	changeMonth: true,
	changeYear: true,
	showButtonPanel: true,
	dateFormat: 'yy-mm-dd',
	minDate: 0
});

jQuery API documentation - datepicker

The minimum selectable date. When set to null, there is no minimum.

Multiple types supported:

Date: A date object containing the minimum date.
Number: A number of days from today. For example 2 represents two days from today and -1 represents yesterday.
String: A string in the format defined by the dateFormat option, or a relative date.
Relative dates must contain value and period pairs; valid periods are y for years, m for months, w for weeks, and d for days. For example, +1m +7d represents one month and seven days from today.

In order not to display previous dates other than today

$('#datepicker').datepicker({minDate: 0});

"mindate" attribute should be used to disable passed dates in jquery datepicker.

> minDate: new Date() Or minDate: '0' is the key for this.

Ex:

$(function() {
    $( "#datepicker" ).datepicker({minDate: new Date()});
});

OR

$(function() {
  $( "#datepicker" ).datepicker({minDate: 0});
});

you can simply use

startDate: 'today'

it working fine for me.

I have created function to disable previous date, disable flexible weekend days (Like Saturday, Sunday)

We are using beforeShowDay method of jQuery UI datepicker plugin.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
var NotBeforeToday = function(date) {
		var now = new Date(); //this gets the current date and time
		if (date.getFullYear() == now.getFullYear() && date.getMonth() == now.getMonth() && date.getDate() >= now.getDate() && (date.getDay() > 0 && date.getDay() < 6) )
			return [true,""];
		if (date.getFullYear() >= now.getFullYear() && date.getMonth() > now.getMonth() && (date.getDay() > 0 && date.getDay() < 6))
			return [true,""];
		if (date.getFullYear() > now.getFullYear() && (date.getDay() > 0 && date.getDay() < 6))
			return [true,""];
		return [false,""];
	}


jQuery("#datepicker").datepicker({
		beforeShowDay: NotBeforeToday
    });

Here today's date is 15th Sept. I have disabled Saturday and Sunday.

you have to declare current date into variables like this

 $(function() {
	var date = new Date();
	var currentMonth = date.getMonth();
	var currentDate = date.getDate();
	var currentYear = date.getFullYear();
	$('#datepicker').datepicker({
	minDate: new Date(currentYear, currentMonth, currentDate)
	});
})

$( "#date" ).datetimepicker({startDate:new Date()}).datetimepicker('update', new Date());

new Date() : function get the todays date previous date are locked. 100% working
