Set date input field's max date to today

I just have a simple line of code like this:

<input type='date' min='1899-01-01' max='2000-01-01'></input>

Is there a simple way to set the max date to "today" instead of 2000-01-01? Or do I have to use Javascript to do this?

JavaScript only simple solution

datePickerId.max = new Date().toISOString().split("T")[0];

<input type="date" id="datePickerId" />

// below trick also works! Thanks jymbob for the comment.
datePickerId.max = new Date().toLocaleDateString('en-ca')

You will need Javascript to do this:

HTML

<input id="datefield" type='date' min='1899-01-01' max='2000-13-13'></input>

JS

var today = new Date();
var dd = today.getDate();
var mm = today.getMonth() + 1; //January is 0!
var yyyy = today.getFullYear();

if (dd < 10) {
   dd = '0' + dd;
}

if (mm < 10) {
   mm = '0' + mm;
} 
    
today = yyyy + '-' + mm + '-' + dd;
document.getElementById("datefield").setAttribute("max", today);

JSFiddle demo

In lieu of Javascript, a shorter PHP-based solution could be:

 <input type="date" name="date1" max="<?= date('Y-m-d'); ?>">

Javascript will be required; for example:

$(function(){
    $('[type="date"]').prop('max', function(){
        return new Date().toJSON().split('T')[0];
    });
});

JSFiddle demo

toISOString() will give current UTC Date. So to get the current local time we have to get getTimezoneOffset() and subtract it from current time

document.getElementById('dt').max = new Date(new Date().getTime() - new Date().getTimezoneOffset() * 60000).toISOString().split("T")[0];

<input type="date" min='1899-01-01' id="dt" />

I am using Laravel 7.x with blade templating and I use:

<input ... max="{{ now()->toDateString('Y-m-d') }}">

Yes, and no. There are min and max attributes in HTML 5, but

> The max attribute will not work for dates and time in Internet Explorer 10+ or Firefox, since IE 10+ and Firefox does not support these input types.

EDIT: Firefox now does support it

So if you are confused by the documentation of that attributes, yet it doesn't work, that's why.
See the W3 page for the versions.

I find it easiest to use Javascript, s the other answers say, since you can just use a pre-made module. Also, many Javascript date picker libraries have a min/max setting and have that nice calendar look.

An alternative to .split("T")[0] without creating a string array in memory, using String.slice():

new Date().toISOString().slice(0, -14)

datePickerId.max = new Date().toISOString().slice(0, -14);

<input type="date" id="datePickerId" />

Is you don't want to use external scripts, but rather set the max limit right in the HTML input element, inline as so:

<input type="date" max="3000-01-01" onfocus="this.max=new Date().toISOString().split('T')[0]" />

I've intentionally added the max attribute with a date far into the future, because it seems Chrome browser change the width of the field once a max attribute is set, so to avoid that, I had it pre-set.

Examples with jQuery and JavaScript:

$('#arrival_date').attr('min', new Date().toISOString().split('T')[0])

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="date" name="arrival_date" id="arrival_date" class="form-control" aria-label="...">

document.getElementById('arrival_date').setAttribute('min', new Date().toISOString().split('T')[0])

<input type="date" name="arrival_date" id="arrival_date" class="form-control" aria-label="...">

it can be useful : If you want to do it with Symfony forms :

 $today = new DateTime('now');
 $formBuilder->add('startDate', DateType::class, array(
                   'widget' => 'single_text',
                   'data'   => new \DateTime(),
                   'attr'   => ['min' => $today->format('Y-m-d')]
                   ));

A short but may be less readable version of one of the previous answers.

   <script type="text/javascript">
    $(document).ready(DOM_Load);

    function DOM_Load (e) {
        $("#datefield").on("click", dateOfBirth_Click);
    }

    function dateOfBirth_Click(e) {
        let today = new Date();
        $("#datefield").prop("max", `${today.getUTCFullYear()}-${(today.getUTCMonth() + 1).toString().padStart(2, "0")}-${today.getUTCDate().toString().padStart(2, "0")}`);
    }
    
</script>

Template: ejs

Using Node.js, express.js and template System ejs:

<input id="picOfDayDate" type="date"  name="date-today"
    value="<%= new Date().toISOString().split("T")[0] %>" 
    min='1995-06-16' 
    max="<%= new Date().toISOString().split("T")[0] %>" 
    class="datepicker" 
>

Yes... you have to use Javascript. My solution below is just yet another option which you can pick up.

var today = new Date().toJSON().slice(0, 10);
var date = $('#date-picker');
date.attr('max', today);

I also had same issue .I build it trough this way.I used struts 2 framework.

  <script type="text/javascript">

  $(document).ready(function () {
  var year = (new Date).getFullYear();
  $( "#effectiveDateId" ).datepicker({dateFormat: "mm/dd/yy", maxDate: 
  0});

  });


  </script>

        <s:textfield name="effectiveDate" cssClass="input-large" 
   key="label.warrantRateMappingToPropertyTypeForm.effectiveDate" 
   id="effectiveDateId" required="true"/>

This worked for me.
