JQuery Date Picker-禁用过去的日期

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..

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');
});
})

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 years0.

In order not to display previous dates other than today

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

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)
});
})

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

minDate:0 works for me.

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);
}
});

"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});
});

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

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

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
});

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

This is easy way to do this

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

also we can disable future days

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

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.

By setting startDate: new Date()

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

you can simply use

startDate: 'today'

it working fine for me.
