Jquery DatePicker Set default date

问题

I Have two date fields where I use DatePicker to pick the dates.

For the first date field, I want today's date as the default date.
For the second date field, I need today + 15 days as my default date

jQuery

$("[name=trainingStartFromDate]").datepicker({ dateFormat: 'dd-mm-yy', changeYear: true});
$("[name=trainingStartToDate]").datepicker({ dateFormat: 'dd-mm-yy', changeYear: true}); 

How do I set the default dates?

I have tried setDate: new Date() for first date but it's not working.

回答1:

Today date:

$( ".selector" ).datepicker( "setDate", new Date());
// Or on the init
$( ".selector" ).datepicker({ defaultDate: new Date() });

15 days from today:

$( ".selector" ).datepicker( "setDate", 15);
// Or on the init
$( ".selector" ).datepicker({ defaultDate: 15 });

回答2:

To create the datepicker and set the date.

$('.next_date').datepicker({ dateFormat: 'dd-mm-yy'}).datepicker("setDate", new Date());

回答3:

use defaultDate()

Set the date to highlight on first opening if the field is blank. Specify either an actual date via a Date object or as a string in the current [[UI/Datepicker#option-dateFormat|dateFormat]], or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.

try this

$("[name=trainingStartFromDate]").datepicker({ dateFormat: 'dd-mm-yy', changeYear: true,defaultDate: new Date()});
$("[name=trainingStartToDate]").datepicker({ dateFormat: 'dd-mm-yy', changeYear: true,defaultDate: +15});

For today's Date

$(document).ready(function() {
$('#textboxname').datepicker();
$('#textboxname').datepicker('setDate', 'today');});

回答5:

First you need to get the current date

var currentDate = new Date();

Then you need to place it in the arguments of datepicker like given below

$("#datepicker").datepicker("setDate", currentDate);

Check the following jsfiddle.

<script  type="text/javascript">
    $(document).ready(function () {
        $("#txtDate").datepicker({ dateFormat: 'yy/mm/dd' }).datepicker("setDate", "0");
        $("#txtDate2").datepicker({ dateFormat: 'yy/mm/dd',  }).datepicker("setDate", new Date().getDay+15); });                       </script>

Code to display current date in element input or datepicker with ID="mydate"

Don't forget add reference to jquery-ui-*.js

    $(document).ready(function () {
        var dateNewFormat, onlyDate, today = new Date();

        dateNewFormat = today.getFullYear() + '-' + (today.getMonth() + 1);

        onlyDate = today.getDate();

        if (onlyDate.toString().length == 2) {
            dateNewFormat += '-' + onlyDate;
        }
        else {
            dateNewFormat += '-0' + onlyDate;
        }
        $('#mydate').val(dateNewFormat);
    });
