Sharath Daniel is on the right lines. A jQuery version: http://jsfiddle.net/2e97L3d0/1/

HTML

<form action="" method="post">
<div class="datetime">
    <input type="text" id="datetime1" placeholder="Enter the starting date"  >
</div>

Javascript

$(document).ready(function(){
$("#datetime1").focus( function() {
    $(this).attr({type: 'datetime-local'});
  });

});

I have tried this solution Here I tried to get YYYY-MM-DD HH:mm pattern placeholder y, u can make your own format Just change value format, data-date-format and add pattern in js too. HTML :

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.10.3/moment.min.js"></script>
<input type="datetime-local" data-date="" data-date-format="YYYY-MM-DD HH:mm" value="2000-01-01T00:00:00">

JS :

$("input").on("change", function() {
    this.setAttribute(
        "data-date",
        moment(this.value, "YYYY-MM-DD'T'HH:mm:ss")
        .format( this.getAttribute("data-date-format") )
    )
}).trigger("change")

CSS:

input {
    position: relative;
    width: 150px; height: 20px;
    color: white;
}

input:before {
    position: absolute;
    top: 3px; left: 3px;
    content: attr(data-date);
    display: inline-block;
    color: black;
}

input::-webkit-datetime-edit, input::-webkit-inner-spin-button, input::-webkit-clear-button {
    display: none;
}

input::-webkit-calendar-picker-indicator {
    position: absolute;
    top: 3px;
    right: 0;
    color: black;
    opacity: 1;
}

A bit tricky, but it works:

Html:

<form action="" method="post">
    <div class="datetime">
        <input id="pholderInput" class="placeholder"  type="datetime-local">
    </div>
</form>

Css:

.placeholder
{
  color: gray;
}

.focused
{
  color: black;
}

Javascript:

var inp = document.getElementById("pholderInput");

var placeholderText = "default text";

inp.value = placeholderText;

inp.onfocus = function(e) {
    if (inp.value == placeholderText)
    {
        inp.value = "";
        inp.className = "focused";
    }
};

inp.onblur = function(e) {
    if (inp.value === "")
    {
        inp.value = placeholderText;
        inp.className = "placeholder";
    }
};

This is kind of a wonky idea, change the input type to text, then it will convert to datetime-local on focus using the below javascript.

<input type="text" id="txtbox" placeholder="Heya">

<script>
  var dtt = document.getElementById('txtbox')
  dtt.onfocus = function (event) {
      this.type = 'datetime-local';
      this.focus();
  }
</script>

Answer 5

Try this code:

$(document).ready(function(){
    $("input[type='datetime-local']").attr('placeholder','date time');
});
