When you have saved username and password for some site Chrome will autofill that username and password, but if you try to get the value for the password input field it is empty String even though there is value there ******.
If you click somewhere on the page no mater where the value of the input type="password" will be filled.
This is Fiddle user/pass of the structure of the html and the console.log command. It cannot be seen here but it can be reproduced on every page that has login form and the username and password are autofilled on the load of the page. If you inspect the value of the field before clicking anywhere else on the site it will be empty String.
This is not the case in Firefox or Internet Explorer it will fill the value of the input element with the password.
I am using Windows 7 Ultimate 64-bit OS and Google Chrome version is 48.0.2564.97 m
Is this normal behavior, bug or?
UPDATE:
If you click on F5 to reload the page and inspect the password field the value for password will be there. If you click the reload button in Chrome in top left corner the value for the password field will be empty string.
This seems to be a bug in Chrome. When Chrome auto-fills a password on an initial page load (but not a refresh), the value appears in the form field on-screen, but querying passwordField.value in Javascript returns an empty string. If you depend on seeing that value in Javascript, this prevents you from doing so. Once the user does any other action on the page, such as clicking anywhere on the page, the value suddenly becomes visible to Javascript.
I'm not actually 100% sure if this is a bug, or if there is a security reason for doing this such as preventing a hidden frame from stealing your password by tricking the browser into filling it in.
A workaround that we have used is to detect the background color change that Chrome makes to fields that it has auto-filled. Chrome colors the background of auto-filled fields yellow, and this change is always visible to Javascript even when the value is not. Detecting this in Javascript lets us know that the field was auto-filled with a value, even though we see the value as blank in Javascript. In our case, we have a login form where the submit button is not enabled until you fill in something in the password field, and detecting either a value or the auto-fill background-color is good enough to determine that something is in the field. We can then enable the submit button, and clicking the button (or pressing enter) instantly makes the password field value visible to Javascript because interacting with the page fixes the problem, so we can proceed normally from there.
Working Answer as of July 8, 2016
Adam correctly stated this is a bug (or intended behavior). However, none of the previous answers actually say how to fix this, so here is a method to force Chrome to treat the autocompleted value as a real value.
Several things need to happen in order, and this needs to only run in Chrome and not Firefox, hence the if.
First we focus on the element. We then create a new TextEvent, and run initTextEvent, which adds in a custom string that we specify (I used "#####") to the beginning of the value. This triggers Chrome to actually start acting like the value is real. We can then remove the custom string that we added, and then we unfocus.
Code:
input.focus();
var event = document.createEvent('TextEvent');
if ( event.initTextEvent ) {
event.initTextEvent('textInput', true, true, window, '#####');
input.dispatchEvent(event);
input.value = input.value.replace('#####','');
}
input.blur();
Edit August 10, 2016
This only works right now in Chrome on Windows and Android. Doesn't work on OSX. Additionally, it will stop working at all in Sept 2016, according to:
https://www.chromestatus.com/features/5718803933560832
Also, I've opened a Chromium ticket.
https://bugs.chromium.org/p/chromium/issues/detail?id=636425
As of August 12, a member of the Chrome team said on the above ticket that the behavior won't be changing because they don't consider it a bug.
Long-term Work-Around Suggestion:
That said, the current behavior has been tweaked from when it was first implemented. The user no longer has to interact with the password input for the value to be reported. The user now just needs to interact (send a mouse or keyboard event) with any part of the page. That means that while running validation on pageload still won't work, clicking on a submit button WILL cause Chrome to correctly report the password value. The work-around then, is to revalidate all inputs that might be autocompleted, if that is what you are trying to do, on submit.
Edit December 13, 2016:
A new Chromium ticket has been opened and is being received better. If interested in changing this behavior of Chrome's, please star this new ticket:
https://bugs.chromium.org/p/chromium/issues/detail?id=669724
Continuing from what Kelderic said, here's my work around. Like a lot of people, I don't need the actual password value. I really just need to know that the password box has been autofilled, so that I can display the proper validation messages.
Personally, I would not use suggested solution to detect the background color change cause by Chrome's autofill. That approach seems brittle. It depends on that yellow color never changing. But that could be changed by an extension and be different in another Blink based browser (ie. Opera). Plus, there's no promise Google wont use a different color in the future. My method works regardless of style.
First, in CSS I set the content of the INPUT when the -webkit-autofil pseudo-class is applied to it:
input:-webkit-autofill {
content: "\feff"
}
Then, I created a routine to check for the content to be set:
const autofillContent = `"${String.fromCharCode(0xFEFF)}"`;
function checkAutofill(input) {
if (!input.value) {
const style = window.getComputedStyle(input);
if (style.content !== autofillContent)
return false;
}
//the autofill was detected
input.classList.add('valid'); //replace this. do want you want to the input
return true;
}
Lastly, I polled the input to allow the autofill time to complete:
const input = document.querySelector("input[type=password]");
if (!checkAutofill(input)) {
let interval = 0;
const intervalId = setInterval(() => {
if (checkAutofill(input) || interval++ >= 20)
clearInterval(intervalId);
}, 100);
}
It is amazing that in 2021 this has not been solved in Chrome yet, I have had issue with autocomplete since 2014 and still nothing.
Chrome functionality autocomplete is misleading for the user, I do not know what are they trying to achieve but does not look good.
As it is now, form appears showing auto-completed text (user/email/pass) to the user, but in the background html - values are not inside of the elements.
As values are not in fields custom validation will disable submit button.
Script that checks fields values will say value is null, which is even more confusing for the user as s/he can see text is there, and can assume it is valid, leading to confusing delete-one insert one character. (Embarrassingly, I have to admit I did not know that you need to click in the body of the HTML, so I wonder how many users don not know the same)
In my case I wanted to have empty field always and then fount out it is just needlessly spent time to make it work.
If we try autocomplete=off we will discover that it is not working. And to validate fields and let say enable button we need to do some trickery.
(Have in mind that I have tried autocomplete=password new-password) and other type of Hocus-Pocus trickery from official resource.
At the end I have done this.
<script>
$('#user').value = ' '; //one space
$('#pass').value = ' '; // one space - if this is empty/null it will autopopulate regardless of on load event
window.addEventListener('load', () => {
$('#user').value = ''; // empty string
$('#pass').value = ''; // empty string
});
</script>
So, it will blink for a split second in some cases in password field with * not ideal but :/ ...
Here's my solution to this issue:
$(document).ready(function(){
if ( $("input:-webkit-autofill").length ){
$(".error").text("Chrome autofill detected. Please click anywhere.");
}
});
$(document).click(function(){
$(".error").text("");
});
Basically, clicking makes the input visible to the user, so I ask the user to click and when they do, I hide the message.
Not the most elegant solution but probably the quickest.
$(document).ready
does not wait for autofill of browser, it should be replaced by
$(window).on("load", checkforAutoFill())
Another option as of Dec. 16 / Chrome 54
I can't get the value of the password field, but, after "a short while", I can get the length of the password by selecting it, which is sufficient for me to enable the submit button.
setTimeout(function() {
// get the password field
var pwd = document.getElementById('pwd');
pwd.focus();
pwd.select();
var noChars = pwd.selectionEnd;
// move focus to username field for first-time visitors
document.getElementById('username').focus()
if (noChars > 0) {
document.getElementById('loginBtn').disabled = false;
}
}, 100);
The workaround specified by Adam:
... detect the background color change that Chrome makes to fields that it has auto-filled. Chrome colors the background of auto-filled fields yellow, and this change is always visible to Javascript even when the value is not. Detecting this in Javascript lets us know that the field was auto-filled with a value, even though we see the value as blank in Javascript
I did like this:-
getComputedStyle(element).backgroundColor === "rgb(250, 255, 189)"
where rgb(250, 255, 189) is the yellow color Chrome applies to auto filled inputs.
I have found a solution to this issue that works for my purposes at least.
I have a login form that I just want to hit enter on as soon as it loads but I was running into the password blank issue in Chrome.
The following seems to work, allowing the initial enter key to fail and retrying again once Chrome wakes up and provides the password value.
$(function(){
// bind form submit loginOnSubmit
$('#loginForm').submit(loginOnSubmit);
// submit form when enter pressed on username or password inputs
$('#username,#password').keydown(function(e) {
if (e.keyCode == 13) {
$('#loginForm').submit(e);
return false;
}
});
});
function loginOnSubmit(e, passwordRetry) {
// on submit check if password is blank, if so run this again in 100 milliseconds
// passwordRetry flag prevents an infinite loop
if(password.value == "" && passwordRetry != true)
{
setTimeout(function(){loginOnSubmit(e,true);},100);
return false;
}
// login logic here
}
Just wrote an angular directive related to this. Ended up with the following code:
if ('password' == $attrs.type) {
const _interval = $interval(() => { //interval required, chrome takes some time to autofill
if ($element.is(':-webkit-autofill')) { //jQuery.is()
//your code
$interval.cancel(_interval);
}
}, 500, 10); //0.5s, 10 times
}
ps: it wont detect 100% of the times, chrome might take longer than 5 seconds to fill the input.
Chrome's intended behavior is that an auto-filled password has an empty value in the DOM until the user interacts with the frame in some way, at which point chrome actually populates the value. Until this point any client side validation or attempt to ajax submit the form will see the password as empty.
This 'populate password value on frame interaction' behavior is inconsistent. I've found when the form is hosted in a same-origin iframe it only operates on the first load, and never on subsequent loads.
This is most evident on ajax forms where the autocomplete password populates on first load, however if that password is invalid and the ajax submission re-renders the form DOM, the autocompleted password re-appears visually but the value is never populated, irrespective of interaction.
None of the workarounds mentioned such as triggering blur or input events worked in this scenario. The only workaround I've found is to reset the password field value after the ajax process re-renders the form, e.g.:
$('input[type="password"]').val("");
After the above, Chrome actually autocompletes the password again but with the value actually populated.
In my current use case I'm using ASP.NET's Ajax.BeginForm and use the above workaround in the AjaxOptions.OnSuccess callback.
$element.is("*:-webkit-autofill")
works for me
With Angular, the new behaviour in Chrome (only allowing autofilled values to be read after the user has interaction with the page) manifests itself as an issue when you're using Angular's validation functionality in certain scenarios (for e.g using standard method/action attributes on the form). As the submit handler is executed immediately, it does not allow the form validators to capture the autofilled values from Chrome.
A solution I found for this to explicitly call the form controllers $commitViewValue function in the submit handler to trigger a revalidation before checking form.$valid or form.invalid etc.
Example:
function submit ($event) {
// Allow model to be updated by Chrome autofill
// #see http://stackoverflow.com/questions/35049555/chrome-autofill-autocomplete-no-value-for-password
$scope.loginModule.$commitViewValue();
if ($scope.loginModule.$invalid) {
// Disallow login
$scope.loginModule.$submitted = true;
$event.preventDefault();
} else {
// Allow login
}
}
Although this is working for us so far, I would be very interested if someone has found another, more elegant work around for the issue.
var txtInput = $(sTxt);
txtInput.focus();
txtInput.select();
This solution worked in my case.
Using jQuery 3.1.1.
If you want make input to be seen as fulfilled, try to trigger blur on it:
$('input[type="password"]').blur();
The autocomplete feature has successfully disabled.
It Works!
[HTML]
<div id="login_screen" style="min-height: 45px;">
<input id="password_1" type="text" name="password">
</div>
[JQuery]
$("#login_screen").on('keyup keydown mousedown', '#password_1', function (e) {
let elem = $(this);
if (elem.val().length > 0 && elem.attr("type") === "text") {
elem.attr("type", "password");
} else {
setTimeout(function () {
if (elem.val().length === 0) {
elem.attr("type", "text");
elem.hide();
setTimeout(function () {
elem.show().focus();
}, 1);
}
}, 1);
}
if (elem.val() === "" && e.type === "mousedown") {
elem.hide();
setTimeout(function () {
elem.show().focus();
}, 1);
}
});
To me none of this solutions seemed to work.
I think this is worth mentioning that if you want to use it for CSS styling you sould use -webkit-autofill property like this:
input:-webkit-autofill~.label,
input:-webkit-autofill:hover~.label,
input:-webkit-autofill:focus~.label
input:focus~.label,
input:not(.empty)~.label {
top: -12px;
font-size: 12px;
color: rgba(0, 0, 0, .4);
font-weight: 600
}
My solution comparing my css to the chrome autocomplete color...
$('input, select, textarea').each(function(){
var inputValue = $(this).val();
if ( inputValue != "" || $(this).css("background-color") != "rgba(255, 255, 255, 0)") {
$(this).parents('.form-group').addClass('focused');
}
});
I tried all the solutions and wasn't working for me so i came up with this.
My problem is i have an input that move the placeholder top when it is filled, off course this is not working when Chrome autofill it.
Only tested in Chrome :
setTimeout(function () {
var autofilled = document.querySelectorAll('input:-webkit-autofill');
for (var i = 0; i < autofilled.length; i++) {
Do something with your input autofilled
}
}, 200);
My version is 95.0.4638.69
I'm facing a similar issue and I solved it by changing my form's name from "login-form" to another name which does not mean anything and solve it. Reason why I didn't remove name attribute is because if I remove name attribute Chrome will look up to id attribute and do the same thing.
Option using onanimationstart event (ReactJs) - Mar 22
I could avoid the needing of verifying periodically if the input was autofilled, as described above using setInterval, by taking advantage of the onanimationstart event. I don't know if it will work in every case, but definitely did the trick for me.
I'll provide a code sample in ReactJs, it may be explanatory enough to be transposed to another context.
First of all, is necessary to add in your input the onAnimationStart property, in such a way that the event is passed as parameter to your function, as following below.
<input
className={componentClass}
placeholder={placeholder}
onChange={handleChange}
onFocus={onFocus}
onMouseEnter={onHover}
onMouseLeave={onHover}
onBlur={onBlur}
disabled={disabled}
name={name}
value={value}
onAnimationStart={e => this.onAnimationStart(e)}
/>
Then let's proceed to the onAnimationStart function body.
onAnimationStart(event) {
// on autofill animation
if (event.animationName === 'onAutoFillStart') {
event.target?.labels[0].classList.add('grm-form__isAutofilled');
}
}
First I verified if the animation name was actually the auto-fill animation, and then I added a class to the first label of my input, this is my use case but can be adapted to solve different problems.
Just set the autocomplete attribute to username for the username field and new-password for the password field;
<input type="text" id="username" autocomplete="username">
<input type="password" id="password" autocomplete="new-password" >
You mentioned:
If you click somewhere on the page no matter where the value of the input type="password" will be filled.
Which is why I simply use $('body').click(); to simulate this first click, after which the value is available in JavaScript.
Also, I set autocomplete="new-password" on my signup form password field, so that the field is not autofilled and users have to fill in a new password.
See this Google Developers page for more information.
It's not a bug. It's a security issue. Imagine if one could just use javascript to retrieve autofilled passwords without the users' acknowledgment.
I am getting a problem to reflect the value in the view, I don't want to load the complete page because its very costly to load the page,
I have two controllers(controller1 and controller2), one service(service1) and two views(modalwindow.html and product.html).
The scenario is:
1.User is on product.html(contains multiple accordions) and user explicitly close all the accordions.
2.User clicked on icon which opened modal window, since it's opened the modal window it's not going to change the URL on the address bar.
3.Modal window(Modalwindow.html ) has the link of show product, since the product page is the active page(show product is the accordion which closed by user explicitly) on the browser.
on the click of link, appropriate accordion should be open on the product.html
I am communicating between modal window controller (controller2.js) and product page(controller1.js) through service (service.js), I am calling controller2
how to fix this issue without loading a complete page
Assuming the modal closes when a product is selected, it can return the value to the calling controller. Then it opens the specified accordion.
I fiddled around in your fiddle. You are mixing two ways of showing your categories in the fiddle: an accordion value, and two boolean values (categoryAccordion, productAccordion). I moved to using one way and it seems to work with the eventCallback. Also, you checked wrongly for your 'args' in the eventCallback. You're passing it back as an array, so get the value out of the array first.
Also, you checked wrongly for your 'args' in the eventCallback.`
if (args[0] == 'Product') {
$scope.productAccordion = true;
$scope.categoryAccordion = false;
} else {
$scope.productAccordion = false;
$scope.categoryAccordion = true;
}
See fiddle.
Should it not be working in your real code, it might have something to do with the following SO question.
I read several threads that talk about how the Address Bar in IE is basically the first one to get focus when using TAB (MSDN's own docs talk about this).
Yet, I have seen situations where this doesn't always have to be the case....
I have a master page and inside my content area is a formView.
It defaults to INSERT view and can never leave it (they can only insert not edit and reading is handled elsewhere)
So on my page load for the page I have:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If fvwLogEntry.CurrentMode = FormViewMode.Insert = True Then
'Set the default field to position the cursor there...hopefully
Dim FCtxtHrEmployeeId As TextBox
FCtxtHrEmployeeId = CType(fvwLogEntry.FindControl("txtHrEmployeeId"), TextBox)
Page.SetFocus(FCtxtHrEmployeeId.ClientID.ToString)
End If
Now that works, when the page loads it sets the cursor to the employeeID text box inside the formview's INSERT template.
HOWEVER, when I hit TAB it takes me to the address bar and THEN if I hit tab again it takes me through the rest of the items on the page.
I set the tab index of the first item to 11 and then incrimented from there (I had read that IE's toolbars have tab indexes too so I thought perhaps using a higher number would bypass those, but again that doesn't REALLY make sense since it would still start at the lowest number, but I gave it a shot thinking it would move forward from where the focus was set.) If I click on the textbox and then hit TAB it DOES move through the page like I would expect.
It is just when the page loads and gets the focus set to the employeeID textbox that hitting tab moves it to the address bar.
I also tried setting the other controls to -1 (those I didn't want it to tab to), still no luck there.
So... what can I do to get around this?
There MUST be a simple way to set the focus to the employeeID textbox and ensure that pressing TAB after that moves to the next control in the formview's insert template and does NOT jump up to the address bar?
The following jquery code seems to be working fine for me..
$(window).load(function () {
$('.myClass :visible:input:enabled:first').focus();
});
$('body').on('keydown', '.myClass :visible:input:enabled:first', function (e) {
if ((e.which == 9) || (e.keyCode == 9)) {
$('.myClass :visible:input:enabled:first').focus();
}
});
I found another better option which is fastest as of what I tried.
Here's the code for that
function handleTabOrder() {
$('.myClass :visible:input:enabled').each(function (index) {
$(this).attr('tabindex', index + 10);
});
$('.myClass :visible:input:enabled:first').keydown(function (e) {
if (e.keyCode == 9 || e.which == 9) {
$("[tabindex=10]").focus();
}
});
}
What I have done here is to assign Tab order to all the visible controls on the page, then I have handled the key down event of only first control(that shifts the control to address bar) and now it shifts the control to next visible input item on the screen..
Its just a work around but works faster than any of the other things mentioned in the thread.
Just write the above function and all it in on-load event of page.
I was having this issue as well. For me, it was being caused by the use of the .select() method in order to bring focus automatically on a text field as soon as the page loaded. I changed my code to instead use JQuery's .focus() method and that resolved the issue.
I faced similar problem in IE. After some analysis I found that, this problem occurs if there is any HTML content outside form.
for example:
<html>
<div id="1">
</div>
<form>
//other code
</form>
</html>
It worked for me, after I moved all HTML inside form tag.
<html>
<form>
<div id="1">
</div>
//other code
</form>
</html>
Have a look at: http://www.w3schools.com/tags/att_global_tabindex.asp
Your txtHrEmployeeId element should have tabindex 1 and all other elements should have higher values.
-1 is not valid
Also verify that the tabindex are correct in the html that gets rendered (right-click in page and "view source").
I realize this is an old post, but an even simpler method is to add a "tab-stop" attribute to the form element with the last tabindex. Then bind a keydown listener and force focus to the first tabindex when the tab-stop is encountered.
Here's a simple example:
<input type="text" tab-stop />
$document.bind("keydown", function(event) {
var attrs = event.currentTarget.activeElement.attributes;
if (attrs['tab-stop']) {
angular.element.find('select')[0].focus();
event.preventDefault();
}
});
};
The answer mentioned in my other post works fine but it made the page take a huge performance hit because with every key press on the page the whole DOM was being searched for the elements.
So I found a new more optimized solution
var myNameSpace = function(){
this.selector = '.myClass :visible:input:enabled:first';
this.myElement = $(selector);
this._body = $('body');
var _self= this;
this._body.on('keydown',_self.selector,function(e){
if ((e.which == 9) || (e.keyCode == 9)) {
_self.myElement.focus();
}
});
};
The general idea being to 'cache' the node to be accessed. No need to traverse the DOM again and again for just selecting.
I had this same problem. It turns out mine was related to the ajax modal popup extenders. a modal popup was being shown, even though technically i could not see it because it was wrapped inside a parent div that was hidden. if you are using modal popup extenders, this could be causing an issue like this.
If you are using JSF or Primefaces, you can make use of:
<p:focus for"formname"></p:focus>
