jQuery Date Picker - disable past dates

问题:

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.

回答1:

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..

回答3:

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

minDate:0 works for me.

回答4:

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);                             
     }
   });

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 today.

In order not to display previous dates other than today

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

回答9:

\"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});
});

回答10:

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
});

回答11:

This is easy way to do this

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

also we can disable future days

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

回答12:

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)
    });
})

回答13:

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

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

回答14:

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.
