Regarding chrome fullscreen message disable - javascript

I need to disable fullscreen message ("you've gone fullscreen") coming on the top when chrome fullscreen mode is activated .
i need to do it through javascript . but it's one of the default functionality of chrome.
can any one help me out ?

It's not possible. As you pointed you it's one of the default functionality of chrome.
and I agree with the comment by mic You can't it's there for security

That message is, if you it can be disabled at all, likely a user preference. I have had my fair share of changing that kind of things for a custom "layer" over windows with an integrated browser and I can tell you it's impossible with javascript without some listener app. We created a C# listener app for that kind of thing that keeps checking a certain text file. We made javascript edit the text file and then let C# work it's hacking magic in some of the user's settings.
You could take a look at Chromium, the stripped down version of Chrome, if that would be of any help ;)
ps: To all the people going mental over changing user settings like that, our customers were old people that were unable to use a computer, and our application's purpose was to do as much as possible for them.

You cannot possibly do that as suggested by these links.

On the other note, why exactly would you want to do that?

React trigger event through mouse click on span [duplicate]

I know there are lots of javascript plugins and libraries to allow users to pick emojis for text inputs, but windows and mac already have native emoji pickers (⊞ Win. or CTRL⌘Space), Is there a way for me to open these native emoji pickers when a user clicks in a text field instead of installing plugins in my website?
I already tried emulate button key press, but it didn't work at all.
Short answer is no.
In order to access any OS feature from javascript, you need a corresponding browser API to support.
AFAIK, there isn't an API for that. There's a discussion here which suggests adding <input emoji /> to standard but seems no traction gained.
Edit: Below is my original answer, revised. Comments pointed out I was focusing on the wrong aspect of the question, I totally agree.
However, the OP obviously has some wrong idea about what you can do in javascript to leverage browser ability. So I think it's still worth clarification.
You can't send arbitrary emulated keyboard event from js and hoping the OS will respond. Were it possible, it'd be a severe security issue on browser's part. Imagine open a website and it fires a series of keyboard event to your OS and wipes out your desktop (totally feasible through shortcuts).
You need to understand the runtime env inside the browser is basically isolated from the one of native OS. Whatever OS feature that's accessible to your javascript is totally up for browser vendors to decide. For security reason, they are super careful in making these decisions.
Also, make a distinction on "what browser can do", and "what browser allows you to do in js". Seeing Chrome has an "Emoji & Symbols" context menu item, doesn't necessarily mean it decides to grant you the same ability in js.
To further clarify why the emulated keyboard event is fundamentally different from the native one, I include a graph here. The blue arrow is how emulated keyboard event flows. The farthest place it can reach is the browser's internal event bus. It never got a chance to reach the OS event bus, so no way to notify native emoji picker.

Why is the javascript psuedo-protocol not working?

So, I'm trying to run on random websites, to play with the javascript psuedo-protocol.
javascript:alert("testtesttest");
And it never works. I've tried 6 websites, and I have no clue what I'm doing wrong. I've tried googling with little success. I'm using the latest version of firefox, and I have javascript enabled.
Firefox disabled it for security reasons, because people were pasting things they were told to in the address bar.
but it still works, if you trigger it from your javascript code.
And in chrome code, I found many cases, a window is initialized with this kind of protocol.
For example if you visit http://www.w3schools.com/jsref/met_win_settimeout.asp
There will be some inside windows to be opened with
javascript:"<html><body%20style='background:transparent'></body></html>"
then later on, the location.href changed to
http://www.w3schools.com/jsref/met_win_settimeout.asp
Any one knows why this kind of change happens, and why it is allowed?
Does it suggest for layer window, the location of the window can be changed to the main page?

Chrome browser and Javascript alert box

My web application uses alert and confirm boxes to display information when a link is clicked.
All browsers display these boxes properly except for Chrome. When I click on a link in Chrome, all I get is the box displayed with one word "Javascript" inside.
It has to work correctly in all browsers, even if the box displayed is constructed a little different in each. It barely works in IE but it does work and if you are going to use that crippled excuse for a browser, you deserve it! ;)
I didn't think this simple problem required a demo in jsfiddle and every one knows what an alert or confirm box looks like, nevertheless if someone needs more clarification please don't just not answer at all, but let me know.
Thanks,
Paul
well alert box is a browser component, therefore all browser vendor uses their own implementation. Since you want same result on all browser, the best you can do is use your own code to produce the result like using modalpopup which will be static around all browser
If you want to ensure cross platform and cross browser compatibility i would use something like:
jQuery Dialogs
Would be alot handier and ensure it looks/works the same everywhere.
Please note jQuery is just an example and any other alert/confirm like JavaScript/CSS would do the job just don't rely on the browser!
Please also note that browsers can change there implementation at any time leaving you stuck if you dont use your own!

Set default home page in JavaScript

How do I create a link to set the user's home page to my URL?
As some people have already answered, it used to be possible in internet explorer (prior to IE 7 I believe, could be wrong though) using something similar to
document.setHomePage('www.example.com');
I don't think any browser supports it anymore though. However, I would definitely try to convince you to do otherwise. Most people won't like having their settings automatically changed, even if it's triggered by a mouse click or other action. It's also quite likely that overzealous 'protection' programs will jump all over it and stamp it as a malicious attack.
As far as I know it's just possible in Internet Explorer
Make my Page your
<a href="javascript:history.go(0)" onClick="this.style.behavior='url(#default#homepage)';
this.setHomePage('http://www.test.de');">Startpage</a>.
I assume you mean put a link in your page to make it the browser homepage? In IE you can do something like:
this.setHomePage('http://www.mysite.com');
I don't think that works in Firefox though.

IE click sound and jQuery

Using jQuery, is there a way to disable the click sound in IE that happens when you post?
The IE click sound is a feature of the browser that you can't control from JavaScript. The only way to disable it is in System Sounds in the Control Panel.
It may very well be possible using this solution: http://www.julienlecomte.net/blog/2007/11/30/
But in short, John is right about it being a browser sound not controlled by javascrípt or anyting else than a registry change, wich a website will not manage to do.
I know the above "trick" has worked before, so if nothing has changed it will still work.
