I was wondering if somebody could tell me if the chromecast allows to display a webpage through chrome tab mirroring with the computer shutdown.
I would like just to tell the chromecast to display a specific webpage and then shutdown my devices and let the screen display that page and refreshing it every X min.
Do you know if it's possible ?
Thank you.
If it is mirroring, no, you won't be able to do that since when you shutdown your computer, everything is gone, and there is nothing to mirror (remember, you are not telling it to show the content of a page, you are telling it to "mirror" your screen and chromecast doesn't have any clue what that content is). You should write a sender and receive app to accomplish that. Also think about user experience: how does user stop that process?

On the iPhone's Instagram app browser(in app) if you open a website that includes html inputs of any type, something strange happens.
In the beginning everything is working, but once you tap an input and type something ( and the keyboard is opened), after you close the keyboard you can't click on anything anymore because all buttons/inputs/elements are clickable in a different location than where they showed ( button is showed in the original 100px location but click events are now on 50px).
It looks like after the keyboard opens the whole location calculation is shifted up(because the keyboard pushes the whole body up)
How to even begin to debug such thing ?
Honestly, I've been there. There is no way to debug the in-app browser (you can try on an iphone device mirroring with Chrome in MAC, but you will eventually fail), but I've tried without success.
It turned out that after digging around with similar issues, there was a caching issue and some disabled features with WP ENGINE from my client. They were able to fix it by allowing some parameters on nginx settings and then the In App browser wasn't stucked anymore.
I know every issue is different, but at this time, I haven't found a way to debug the In - App browser.
I can't speak to iOS specifically, but there definitely are ways to remote debug things.
My go-to for stuff like this (speaking from experience of browsers on gaming consoles) is Weinre: https://people.apache.org/~pmuellr/weinre/docs/latest/Home.html You get something similar to Chrome Developer Tools, but it works over a Socket.IO connection.
Another tool I like to use is Fiddler. While it won't help you with your DOM issues, if you ever need to debug network stuff on oddball devices, it's perfect. It serves as a proxy server and can intercept all your connections, including HTTPS. https://www.telerik.com/fiddler
Turns out, that it's a fixed position and it's not supported, which means when keyboard is closed, the system will push back the whole view but click events stay up (because it's being pushed up when you open a keyboard).
So instead of make it an absolute modal, which has it's own problem, we keep it fixed, BUT, we do the pushing up/down by our own.
We could just push the screen back down on input unfocused, but if user click the next field you get unwanted behavior, so we create a delay based machine like so :
var isfocused=0;
var focusTimer=0;
$("input").blur(function() {
isfocused=0;
focusTimer = setTimeout(focusDone, 150);
});
$("input").focus(function(){
isfocused=1;
});
function focusDone(){
if(isfocused===0)
$(window).scrollTop(0,0);
clearTimeout(focusTimer);
}
This works great on social browsers, with fixed positioned modals that has inputs inside them.
I need to cast an entire webpage (which includes images, videos, iframes and carousels) to a chromecast enabled TV.
Once loaded, the webpage is auto scroll enabled and hence keeps showing few images, videos and iframes (think of it like a looped slideshow).
I know there's an option in the chrome browser itself to cast a tab/entire desktop, but it would require my laptop/computer screen to be open all the time.
I also came across chromecast for web app docs: https://developers.google.com/cast/docs/chrome_sender/integrate , but as far as I can figure out, it will help only to cast videos but not iframes/carousels embedded in my website.
Any suggestions how to achieve this? The requirement is to show an advertisement kind of data to the TV in every 3 hours. All this cannot be automated fully I guess?
Yes, you can do this. You just need to create a custom receiver app, which is basically just an HTML page that implements the cast receiver framework javascript. https://developers.google.com/cast/docs/caf_receiver/basic
I am trying to implement a hard limit on a how long a web page can load via a Chrome extension. I have seen a number of implementations that suggest using a content script to call window.stop(), but in some cases the browser is never going to execute that JavaScript because it's still attempting to load a page that is going to time out. An example of such a site is http://blackhole.webpagetest.org.
At a very basic level, I need the extension to be able to hit the "Stop" button in the browser after a specified amount of time.
Any suggestions on how to accomplish this in Chrome?
I would like to create one website. This website will have behave differently if I am viewing it at a specific event via a kiosk. The kiosk, will just be an iPad. I believe I can figure out how to lock down the iPad to act like a kiosk and just show my website based on this http://www.webascender.com/Blog/ID/447/How-to-Setup-Kiosk-Mode-Lock-Your-iPad-to-Just-One-App#.U9Fx3oBdVX4
But what I am asking is, in code, is there a way to detect that I am in 'kiosk' mode and show different pages? For example, if you are at home(or anywhere that is NOT the event) you should be able to hit my website to find out all about my company and to view your existing profile. You should be able to see these same pages on the 'kiosk'(the iPad while at an event) but you will now see additional pages such as pages dealing with the specific event and payment pages. Vice-versa you might be able to see additional pages on the website while at home that you will not see while in 'kiosk' mode.
I do not know if the solution is tools/language dependent as we have not settled yet on all tools/languages/frameworks we will be using to build the site and so I am open to all but we will definitely have some javascript/css/html.
I believe you will need to write a native app in order to detect whether you are in 'guided access' aka 'kiosk' mode.
Taken from Detect or react to Guided Access?
NSLog(#"Accessabilitiy enabled: %#", UIAccessibilityIsGuidedAccessEnabled() ? #"YES" : #"NO");
if (!UIAccessibilityIsGuidedAccessEnabled()) {
// show something since I'm not in guided access
}
If you want to know when it changes...
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(guidedAccessChanged) name:UIAccessibilityGuidedAccessStatusDidChangeNotification object:nil];
- (void)guidedAccessChanged
{
// do something when guided access changes
}
If you must work with a website then what you can do is write a native app that embeds a UIWebView. This class allows you to show websites within a native app. So, what you could do with this method is pass along the guided access setting to your website so that it can adjust itself accordingly.
If you know the IP address you can direct views using PHP (and probably a host of other programs). Or you can lock the iPad to only open a specific URL (http://mysubdomain.mydomain.com) and only have pages that you want viewed by the kiosk. I'm sure there are a mess of other ways too.
I need to capture webcam images from inside browser. I am planning to use Flash but since am not experienced in it, before jumping into it, I want to ask you experts :
Will Flash ask for Webcam permission every time user refreshes the page ? Isn't there some global security setting to allow a website.
Is it essential to display the webcam feed on the browser to be able to capture it / take snapshot and upload to server. I totally don't want to show live feed on the webpage, all I want is to take snapshots and upload it in the background.
The purpose of above requirement is that we are trying to add proctoring to our online assessment platform, and hence we don't want to reload / ask for permission again every time candidate views a new test page. One alternative can be making the whole site a single page webapp, but definitely that will add quite some overhead.
