Chrome ignores autocomplete="off"

Question

I've created a web application which uses a tagbox drop down. This works great in all browsers except Chrome browser (Version 21.0.1180.89).

Despite both the input fields AND the form field having the autocomplete="off" attribute, Chrome insists on showing a drop down history of previous entries for the field, which is obliterating the tagbox list.

Answer 1

Prevent autocomplete of username (or email) and password:

<input type="email" name="email"><!-- Can be type="text" -->
<input type="password" name="password" autocomplete="new-password">

---

Prevent autocomplete a field (might not work):

<input type="text" name="field" autocomplete="nope">

Explanation:

autocomplete still works on an <input>despite having autocomplete="off", but you can change off to a random string, like nope.

Others "solutions" for disabling the autocomplete of a field (it's not the right way to do it, but it works):

1.

HTML:

<input type="password" id="some_id" autocomplete="new-password">

JS (onload):

(function() {
    var some_id = document.getElementById('some_id');
    some_id.type = 'text';
    some_id.removeAttribute('autocomplete');
})();

or using jQuery:

$(document).ready(function() {
    var some_id = $('#some_id');
    some_id.prop('type', 'text');
    some_id.removeAttr('autocomplete');
});

---

2.

HTML:

<form id="form"></form>

JS (onload):

(function() {
    var input = document.createElement('INPUT');
    input.type = 'text';
    document.getElementById('form').appendChild(input);
})();

or using jQuery:

$(document).ready(function() {
    $('<input>', {
        type: 'text'
    }).appendTo($('#form'));
});

---

To add more than one field using jQuery:

function addField(label) {
  var div = $('<div>');
  var input = $('<input>', {
    type: 'text'
  });
  
  if(label) {
    var label = $('<label>', {
      text: label
    });
    
    label.append(input);
    div.append(label);    
  } else {
    div.append(input);    
  }  
  
  div.appendTo($('#form'));
}

$(document).ready(function() {
  addField();
  addField('Field 1: ');  
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="form"></form>

---

Works in:

• Chrome: 49+

• Firefox: 44+

Answer 2

UPDATE

It seems now Chrome ignores the style="display: none;" or style="visibility: hidden; attributes.

You can change it to something like:

<input style="opacity: 0;position: absolute;">
<input type="password" style="opacity: 0;position: absolute;">

In my experience, Chrome only autocompletes the first <input type="password"> and the previous <input>. So I've added:

<input style="display:none">
<input type="password" style="display:none">

To the top of the <form> and the case was resolved.

Answer 3

It appears that Chrome now ignores autocomplete="off" unless it is on the <form autocomplete="off"> tag.
