Is there any option in any IOS browser to print from javascript code without opening dialog box.
For example is there option like kiosk-noprint in IOS browser?
There is no error but I cannot find any option to prevent the dialog popup

I have a page with a JavaScript based idle sign off script as well as a file upload feature. I noticed that if I opened the dialog then allowed the idle sign off to trigger a redirect to the login page the open file dialog remained open. I would have expected it to be closed when the originating page is unloaded.
Given an input with type of file:
<input type="file" name="file" />
If the user clicks and opens the native file picker dialog window but while it is open the page or frame is redirected via a script the dialog does not close. A script like this should duplicate the behavior:
$('input[type=file]').on('click', function(){
setTimeout(function(){
window.location.href = "some other page";
}, 2000);
});
You can see the behavior here: https://jsfiddle.net/we40rpfs/1/
I was able to reproduce this in on Windows10 in IE Edge, Chrome 86.0.4240.198 and Firefox 82.0.2.
Interestingly in IE and Chrome the file picker host also crashes sporadically when the user attempts to close or cancel the dialog. Firefox might also crash it as well but I was unable to see it happen.
Is there any way to detect that this dialog is open and programmatically close it before redirecting?
It's the expected behavior that the dialog is still open without any user interaction.
At least, you can't programmatically close the dialog with JavaScript. The file dialog is in OS level which can't be reached with JavaScript for security reasons. All interaction with the file dialog must come from the user actually pressing mouse on the system dialog.

window.print() method will open print preview dialogue box. How to close that box using javascript.
Can we use Custom Events to dispatch "esc key", but don't know where to dispatch(Element).
I am afraid that you can't do this. Just like alert dialog, the print dialog will block the browser until you click cancel button or save button. You can try to run some codes when the print dialog is hanging, then you will find you can just input the codes in console but there is no output and the codes are not running. So I think you can't do that using javascript.
I am using window.open(url,'_blank') to open a url inside an iframe. But site is not opening and its showed as popup blocked. Is there any way to enable popup via javascript?
You may have to manually enable the popup on the URL right side of chrome, there should not be any way of automatically unblocking the popup using javascript as it will just defeat the purpose of popup blocking and all popups from all webpages will just go do that and show.
You can show a popup which checks the popups are enable or not.
If browser popup disable then you can show an alert or prompt to inform the user. And on click of prompt ok button you can just white your java Script code.
Is there a way to disable the print preview in Chrome using javascript? I need to open a pop-up in a web application with some text to print; in this pop-up I have the following code when the page is loaded:
$(document).ready(function () {
window.print();
});
a simple JavaScript that opens the print preview page; now, what happens is that the print preview page behaves like a modal dialog: I cannot navigate anymore in the application that has opened the print page (even though the links are clickable). This behavior doesn't show up if the normal system dialog is available (and in fact, I don't have this problem in IE Explorer and in Firefox).
So, is there a way to tell Chrome to disable the print preview through a JavaScript?

No (through javascript). Google like every other company, likes to keep a consistent user experience. If programmers were able to change how chrome worked on different pages beyond html, that would be a poor user experience.

Instead, you could have a new window open with the same data and hava javascript do a print. The previous window would work normally (assuming the new window doesn't open in a new tab because of add-ons/configuration).
We have an issue where Chrome's "Print Preview" does not print our pages correctly. If you use the "Use System Print Dialog link" (Ctrl+Shift+P), it prints our page fine (almost identically to Firefox).
We have a button on our page that calls window.print() to open the print dialog. However, in Chrome it opens to the "Print Preview" dialog which ends up not printing our page correctly.
Is there away with JavaScript to print directly to the "system print dialog" in Chrome?
P.S.
I do know how the end user can disable the Print Preview in chrome://flags, but what I want to know is there anyway to prevent it from showing when I programmatically call window.print() (or similar) regardless of user settings.
Print dialogs are not scriptable using JavaScript. They're proprietary parts of browsers themselves.
Hi i am facing the same issue... I even tried firing keyboard event ctrl+shift+P from my script in order to show system print dialog.
You can fire a keyboard event and that issue is successfully dispatched, however the value of keyCode that the browser receives is always 0 (instead of ASCII value of ‘P’)
There is a bug logged https://bugs.webkit.org/show_bug.cgi?id=16735 against webkit for the same… and here are some posts http://code.google.com/p/chromium/issues/detail?id=27048, http://code.google.com/p/chromium/issues/detail?id=52408 mentioning the same issue in Safari and Chrome…
