How do I simulate placeholder functionality on inp

Question

It's impossible to use placeholder on date fields but I really need it.

I want two date inputs with texts "From" and "To" on each one as placeholders.

Answer 1

The HTML5 date input field actually does not support the attribute for placeholder. It will always be ignored by the browser, at least as per the current spec.

As noted here

Answer 2

The input[type="date"] DOMElement only takes the following value: YYYY-MM-DD, any other format or text with be skipped.

Live Demo

HTML

<input type="text" placeholder="bingo" />
<input type="date" placeholder="2013-01-25" />

Pure JavaScript

window.onload = function () {
    /* Grab all elements with a placeholder attribute */
    var element = document.querySelectorAll('[placeholder]');

    /* Loop through each found elements */
    for (var i in element) {
        /* If the element is a DOMElement and has the nodeName "INPUT" */
        if (element[i].nodeType == 1 && element[i].nodeName == "INPUT") {

            /* We change the value of the element to its placeholder attr value */
            element[i].value = element[i].getAttribute('placeholder');
            /* We change its color to a light gray */
            element[i].style.color = "#777";

            /* When the input is selected/clicked on */
            element[i].onfocus = function (event) {
                /* If the value within it is the placeholder, we clear it */
                if (this.value == this.getAttribute('placeholder')) {
                    this.value = "";
                    /* Setting default text color */
                    this.style.color = "#000";
                };
            };

            /* We the input is left */
            element[i].onblur = function (event) {
                /* If the field is empty, we set its value to the placeholder */
                if (this.value == "") {
                    this.value = this.getAttribute('placeholder');
                    this.style.color = "#777";
                }
            };
        }
    }
}

Performance review

In this exact case, with 2 input elements, Pure JavaScript is ~40% ± 10% faster.

With 32 input elements, the difference remains the same (~43% ± 10% faster for Pure JS).

Answer 3

use this input attribute events

onfocus="(this.type='date')" onblur="(this.type='text')"

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<div class="container mt-3">
  <label for="date">Date : </label>
  <input placeholder="Your Date" class="form-control" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date">
</div>

Answer 4

I'm using this css method in order to simulate placeholder on the input date.

The only thing that need js is to setAttribute of the value, if using React, it works out of the box.

input[type="date"] {
  position: relative;
}

input[type="date"]:before {
  content: attr(placeholder);
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background: #fff;
  color: rgba(0, 0, 0, 0.65);
  pointer-events: none;
  line-height: 1.5;
  padding: 0 0.5rem;
}

input[type="date"]:focus:before,
input[type="date"]:not([value=""]):before
{
  display: none;
}

<input type="date" placeholder="Choose date" value="" onChange="this.setAttribute('value', this.value)" />

Answer 5

I'm using the following CSS only trick:

  input[type="date"]:before {
    content: attr(placeholder) !important;
    color: #aaa;
    margin-right: 0.5em;
  }
  input[type="date"]:focus:before,
  input[type="date"]:valid:before {
    content: "";
  }

<input type="date" placeholder="Choose a Date" />

Answer 6

Ok, so this is what I have done:

$(document).on('change','#birthday',function(){
    if($('#birthday').val()!==''){
        $('#birthday').addClass('hasValue');
    }else{
        $('#birthday').removeClass('hasValue');
    }
})

This is to remove the placeholder when a value is given.

input[type="date"]:before {
  content: attr(placeholder) !important;
  color: #5C5C5C;
  margin-right: 0.5em;
}
input[type="date"]:focus:before,
input[type="date"].hasValue:before {
  content: "" !important;
  margin-right: 0;
}

On focus or if .hasValue, remove the placeholder and its margin.
