i will set today date in datepicker input type date in chrome.

$(document).ready( function() {
    var now = new Date();
    var today = now.getDate()  + '/' + (now.getMonth() + 1) + '/' + now.getFullYear();
    alert(today);
    $('#datePicker').val(today);
});?

but it's not working

Edit This jsFiddle - Please try in chrome.

Your code would have worked if it had been in this format: YYYY-MM-DD, this is the computer standard for date formats http://en.wikipedia.org/wiki/ISO_8601

Datetimepicker always needs input format YYYY-MM-DD, it doesn't care about display format of your model, or about you local system datetime. But the output format of datetime picker is the your wanted (your local system). There is simple example in my post.

document.getElementById("datePicker").valueAsDate = new Date()

should work.

var today = new Date().toISOString().split('T')[0];
$("#datePicker").val(today);

Above code will work.

Jquery version

var currentdate = new Date();

$('#DatePickerInputID').val($.datepicker.formatDate('dd-M-y', currentdate));

    1 console.log(new Date())
    2. document.getElementById("date").valueAsDate = new Date();

1st log showing correct in console =Wed Oct 07 2020 00:40:54 GMT+0530 (India Standard Time)

2nd 06-10-2020 which is incorrect and today date is 07 and here showing 06.

For me the shortest way to get locale date and in correct format for input type="date" is this :

var d = new Date(); 
var today = d.getFullYear()+"-"+("0"+(d.getMonth()+1)).slice(-2)+"-"+("0"+d.getDate()).slice(-2);

Or this :

var d = new Date().toLocaleDateString().split('/');
var today = d[2]+"-"+("0"+d[0]).slice(-2)+"-"+("0"+d[1]).slice(-2);

Then just set the date input value :

$('#datePicker').val(today);

to me the shortest way to solve this problem is to use moment.js and solve this problem in just 2 lines.

var today = moment().format('YYYY-MM-DD');
$('#datePicker').val(today);

You can only use date in input type="date" as in format YYYY-MM-DD

I have implemented helper as formatDate in NODE.js express-handlebars, don't need to be worry ... just use format as described in first line.

e.g:

< input type="date" id="date" name="date" class="form-control" value="{{formatDate invoice.date 'YYYY-MM-DD'}}" />

Update: I'm doing this with date.toISOString().substr(0, 10). Gives the same result as the accepted answer and has good support.

I usually create these two helper functions when using date inputs:

// date is expected to be a date object (e.g., new Date())
const dateToInput = date =>
  `${date.getFullYear()
  }-${('0' + (date.getMonth() + 1)).slice(-2)
  }-${('0' + date.getDate()).slice(-2)
  }`;

// str is expected in yyyy-mm-dd format (e.g., "2017-03-14")
const inputToDate = str => new Date(str.split('-'));

You can then set the date input value as:

$('#datePicker').val(dateToInput(new Date()));

And retrieve the selected value like so

const dateVal = inputToDate($('#datePicker').val())
