Cursor appears before field loads on Mobile Safari - javascript

My web app includes a login button which dynamically adds a form to the DOM tree (with a username and password field) and sets the focus to the username field. It all works fine, however the cursor appears fractionally before the field has appeared on screen which I don't like. This being mobile Safari I can't put a setTimeOut on the focus command (the focus command must be in the function called by the users click, calling it from another function causes Safari to ignore it). I can't use a nasty delay as that also delays the loading of the form and the cursor still pops up before the field loads.
Anyone got any (preferably simple) ideas?

mobile keyboard popping when slidetoggle is used

I am working on a mobile webpage. I have one element, that has a text field, that I call jQuery slideToggle on, so it can be hidden from view when the user wishes to dismiss it.
It works fine on browser, even on simulating a device, and in an actual device. The problem is that when the button to dismiss it is clicked on an iPhone, the keyboard pops up.
I already checked if the is the text field is being focused, but seems not to be the case.
What might be the reason for this behavior?

Can't focus elements on load in Chrome - very weird bug (in Chrome?)

I have a very, very weird issue that only seems to be an issue in Chrome.
When a user comes on the website, the user cannot focus any element (via mouse click, if they focus it via tabbing, the elements don't get the 'focused' state either) and that's only an issue in Chrome. That is, until the user resizes the window, minimizes the window, opens a new tab, opens developer tools, etc. Reloading the page does nothing. However, as soon as focus is "enabled", the user can navigate/refresh with purging cache, etc., close the browser and open it again, and everything works normally - the elements get the 'focused' state normally.
This behaviour can only be reproduced in Chrome and not on localhost.
The difference between localhost and beta environment is:
beta env requires authentication (basic http auth)
files in development env are concated in a single JS and single CSS file and both are minimized
beta env includes hotjar, while there's no hotjar on localhost
There are no custom event listeners that would listen for the 'resize' event. There are no errors in console and all javascript that doesn't depend on focused element state gets executed correctly. Hover events and all CSS styling that depends on hovered state all work correctly.
The main issue is, that a form which has to be filled out and includes a datepicker, cannot be filled out and thus the users can't really interact with the page. Datepicker doesn't open and, as the input elements don't get the focused state, they don't visually change (CSS :focused selector isn't working either) and thus give the impression to the user that they cannot type in the normal text inputs (which works, after clicking on the input, it is possible to type in the input).
I have tried removing hotjar and the problem persisted. The only thing that made the problem go away was removing the basic auth, however, that is not an option in this stage (it's a closed beta test, so we need to limit the access only to the users with password).
I also find it extremely odd that basic auth would interfere with the focused state of elements, especially as the error persists after you refresh and only goes away as soon as you interact with browser itself (minimize, open new tab, do anything that resizes your browser window or document), after that it works correctly and there are no errors whatsoever.
The problem only started to appear recently, but I do not believe it's an issue with the app itself, as I tried rolling back to a couple months old build and the problem persists. All of that makes me believe it's a bug in Chrome, but what can be done to fix it?
EDIT: I also tried to add autofocus property to an input element and, in beta environment, it doesn't get focused.
So it seems it indeed is a Chrome bug that's present both on mobile (Android and iOS) Chrome browsers, as well as desktop Chrome browser (tested both on a Windows and a Mac). I submitted an official bug report. In the bug report, a fellow user made a website that's accessible only through basic auth and only has 2 basic inputs, the input should get a red border on focus. As expected, after opening the webpage in Chrome (for ease of use - incognito mode), the input doesn't get focus and the border doesn't change.
For those who are also affected by this bug in Chrome, you can track the bug progress here: https://bugs.chromium.org/p/chromium/issues/detail?id=740652
Meanwhile, here's a hacky solution for those interested:
$(document).on("ready", function() {
var $inputs = $("input");
$inputs.off("click.trick");
if (!sessionStorage.fixedChromeFocus) {
sessionStorage.fixedChromeFocus = "true";
$inputs.on("click.trick", function() {
var win = window.open("/", "_blank");
setTimeout(function() {win.close()}, 1);
$inputs.off("click.trick");
});
}
});
The goal is to, somehow, interact with the browser outside of the current page, to make it somehow lose focus. You cannot use JS to minimize browser, cannot resize it, cannot open dev tools. What you can do, though, is open a new window. Of course, if you open a new window immediately, a pop-up blocker (as most people have it) will block it and the window itself (or rather your current tab) won't lose focus. Opening a new window can only be done as a reaction to a user event (without triggering potential pop-up blocker).
I also use some browser detection so the code will only be executed for Chrome and, using server-side conditioning, only for builds that include basic auth.
What the code does, quite self evidently, is that as soon as a user clicks on an input, it opens a new tab and quickly closes it, 1ms later. To prevent this from happening all the time, on every page load, sessionStorage, which gets cleared automatically after tabs from that domain are closed, is used (and we've already established that once focus starts working correctly, it will work as long as you keep your browser open).
The effect of this code is that the user will see a quick white flash the first time he clicks on the input, but everything will work correctly

Javascript - Input/text can't get focus (Chrome)

I'm doing a registry form, one of the validations is to check the database for existing username. To do that I open a php page in a separate hidden frame that checks the database and then calls a javascript funcion on the main frame to show an icon indicating if the user exists or not.
everything works fine, except in chrome that when the php page is open, the input/text loses focus and there's no way to get it back. I've tried calling focus on the element, using timeout as i've seen this solves similar issues in chrome, but nothing works so far...
any ideas?
Thanks.

iOS jumps and targets new field when using the autofocus

I have a login page that contains the usual email and password fields, as well as a log in button. For usability, the autofocus HTML5 attribute has been used on the email field.
When loading the page on iOS, you can tell by the green border that the field has the focus, but because of iOS limitations, the focus is not fully applied to the field, as you can see here with the keyboard not being displayed:
The first thing the user does is touches the email field, but as far as iOS is concerned, you're clicking on a different part of the page. The focus is actually given to the password field instead, because the page shifts upwards to make way for the keyboard that did not display previously:
In a similar behaviour, if the user touches on the password after page load, the log in button is clicked instead and validation errors appear.
Is there any way to solve this?
Why not disable the autofocus when you show the page on iOS?
It would be very annoying when user enter a website and the keyboard pops up without any actions on the page.
I even can't think of any website popping up the keyboard on the load.

jquery dialog's input fields freezes in firefox

I have some jquery dialogs added in my application where in one scenario I open up a 1st dialog and upon entries into some field I am prompted with a message containing some server side messages and that prompt is again a 2nd jquery dialog. that means i have 2 dialogs opened over each other. so when i click on the top most(2nd) dialog then both the dialogs' $('#div1').dialog('close') and $('#div2').dialog('close') are called I am redirected to another page. Now here is what the issue arises, I am on new page with both dialogs closed, now if I open up the 1st dialog again it opens up but with everything frozen. I mean it literally takes no input but a cursor keeps blinking in first field. This happens only in Firefox, in Chrome it works like a charm.
