I'm experimenting with the Speech Synthesis API. I have the following code:
var message = new SpeechSynthesisUtterance("Hello");
window.speechSynthesis.speak(message);
The code works perfectly fine, however it only works when the user has clicked or interacted with the current page on the browser. I get the following warning on the Chrome console when attempting to run the code without interacting with the page first:
speechSynthesis.speak() without user activation is no longer allowed since M71, around December 2018. See https://www.chromestatus.com/feature/5687444770914304 for more details
I want the code to run as soon as a user loads the page without them having to interact with the page first.
I looked into simulating a page click with javascript/jquery like this:
$('#randomElementOnPage').trigger('click');
And then running the speech code, but it doesn't seem to trick the browser.
Any solutions/advice is appreciated.
Thanks.
EDIT: Since there doesn't seem to be any solutions, are there any browser/audio settings in Chrome, etc I can change for myself to allow this to work for myself only. Someone suggested going to chrome://settings/content/sound and adding the site to the list of allowed sites for audio. However, this does not seem to work either.
If, as it's said in your EDIT, you want to use your code on your own computer (computers in some way controlled by you), you may instead use some automation tool (and it will press buttons/interact with the page on your behalf).
I don't know what is trending now. Puppeteer or Intern or something like that, probably, will be an overkill (and puppeteer is headless, as far as I know). A long time ago, I personally, used AutoIt.

Background / use case
I would like to automate some page interactions by pasting a script into my browser console (normally Chrome/Chromium or in my case IE11 because.. don't ask.)
Typical steps in one iteration:
(initial) Visit a page, wait until it is fully loaded.
Fill in form values automatically, trigger some buttons, submit.
Wait for new page after form submission.
Go to 'next page', wait until it is fully loaded, start over with a new set of form values.
The "Visit a page" or "Go to 'next page'" could either happen by clicking a button, or by setting document.location.href explicitly.
The "wait for ..." can take up to 30 seconds in both cases. Not for any good reason, just because.
I am aware (to my current understanding) that the js (event listeners etc) included in a page does not survive a new page load. I am specifically asking about js called form the browser's developer console.
Question
How can I register an event listener from the console for "page load complete" after setting document.location.href, or doing something equivalent?
As mentioned, in my use case I would need to do this with Internet Explorer 11. But I assume people are more familiar with the developer tools in Chromium or Firefox. Any answer that works in one of these browsers is welcome, just mention which browser you tried this with.
Limitations
I do not control the web application where I want to do this, I only control my browser. It also does not look like the developers of said application would be likely to respond to feature requests or wishes.
Perhaps someone will suggest to do this with an iframe. I am not sure this will work. If it does, this would be a different question.
Perhaps someone will suggest some kind of browser simulator tool to use instead of the console. Unfortunately I need/want to make this work on Internet Explorer in a corporate Windows environment with limited privileges. Alternative tools can be mentioned, but there is a reason why I focus on browser console.
How can we detect through PHP or maybe in node.js or other languages if a web page crashed (without the browser EXITing) so that when a user press the "reload" button on the "Aw Snap" page in chrome certain specific content inside the page can be shown in this particular case (crash case).
In a crash without EXIT, a browser shows per example in Google Chrome the famous "Aw, Snap!" page.
I don't want to know how to capture if the user refreshed the page or the page reloaded which can be known quite easily with different methods [one example see this PHP this code which can detect if users refreshed the page on major desktop/mobile browsers except IE unfortunately this code does not capture a crash event and the fact that user might request again the same page after a crash.
I tried using "register_shutdown_function", and some other maneuvers using connection PHP functions like "connection_aborted" etc... but with no success. I figure out a sloppy way through the use of session variables but probably there are better clever manoeuvres.
Any help or suggestion would be greatly appreciated. Any solution in nodejs will be also welcomed.
web brower crash because too many process from your browser to PC of Client.
this crash can't detected by php because PHP server scripting. and you have question.., why not use JS for detect crash of browser?, because JS created just for controller website,. if you force to checked that use ajax, node, etc you can't do that, why? because the problem comes suddenly
and detected crash browser from php is impossible.
I spent a lot of time to search for solution but without result.
I check this topics :
Website Bookmark/ Shortcut Icon for Android Help. Cant get passed standard ribbon icon
Whick is very nice ,but here user must click on bookmark.That`s not what i need. May be button,or automatic script that prompt user for this and created automaticaly.For example something like this :
http://socialmedia.biz/2012/02/21/encourage-visitors-to-save-your-site-as-a-mobile-shortcut/
But it`s work only on Apple devices .. What im looking for is a similar solution for android.
Is this possible at all?
May be the only solution is to create simple app that act like a shortcut to my web page?
The page that is talking about has a mobile version ..
Have you looked here [for Chrome]? https://developers.google.com/chrome/mobile/docs/installtohomescreen

If this is "allowed" and doesn't go against too many guidelines, this might be your only option. Basically you'd want to create a one Activity application and all it does is call the default Intent for your web page. This should push the user into the default Browser.
You could put the app in the Google Play store and link to it from the site or a script. I'd call the app something like "SITE_NAME Web Shortcut" and make it clear in the description that the only purpose is to launch the browser -- as previously mentioned this doesnt "feel" like something that should be in an app store, and if users think they're getting something extra you'll definitely get bad reviews.
(I'd also make the Activity with #style/Theme.Transparent)
Please be aware that Chrome has changed the way that installs web apps.
Here are the details: https://developers.google.com/web/updates/2018/06/a2hs-updates
There is an install criteria now:
The web app is not already installed
Meets a user engagement heuristic
Be served over HTTPS
Includes a Web App Manifest that includes:
short_name or name
icons - must include a 192px and a 512px icon
start_url
display - must be one of fullscreen, standalone, or minimal-ui
prefer_related_applications must not be present, or be false
-Registers a service worker with a fetch handler
I have set my Cocoa app to be an URL handler for com_example_myapp: protocol (using this great tutorial). So, the link in Safari <a href="com_example_myapp://link"> now opens my app. Cool.
But before I give the user the link in the web browser, how can I determine whether the client's OS is capable to handle it? How to check this via JS (PHP, ...)?
I have found a lot of solutions (mostly for Mobile Safari) but cannot find anything cross-browser compatible.
From what I know, Chrome doesn't support this. You can try using a try/catch but it won't return anything. You can use your other references and put a specific call in their for Safari.
Lastly, I haven't tested it, but you can bind something to the window to see if it blurs.
$(window).blur(function() {
//code to see if it blurred on a setTimeout
}
Then record the date of creating it and see if it's within 1 second so when they come back you can destroy the timer if it's still there.
Just ideas though...
There is something seriously wrong here. I am about a 100% sure the confirm method is causing serious issues with sessions on Safari. The confirm prompt basically asks the user to make sure he/she wants to go through with an action before pulling off a Jquery POST. This works fine on every other browser, but on Safari the users session data gets deleted and they get logged out upon refreshing the page. I removed the method and everything is back to normal. Has anyone experienced this before? Very strange... shakes fist at apple
Edit: I tried using Jqueries Dialog widget and I am experiencing the same issues. What do you think is going on?
Edit2: For those who are curious, the alert doesn't wipe out the session data, it just brings the control back to the client end therefore the browser isn't really in touch with its server side. This comment explains it best:
You have to be mindful of where your code is running when you are
using ASP.NET. In your example, since you are using the Session
object, you are running on the server. Your web server has no way of
popping up an alert dialog on the user's machine. Instead, it has to
write JavaScript code to the client, which can then execute this code
and give the user an alert. So, you need to change your approach. If
you need the alert, you will need to feed the information to the
client, and have the entire check take place there, in which case you
lose access to your session variable (stored on the server), so the
only comparison you will be able to do is based on something on that
form or else something that you write out to the client machine.

It's ridiculous to see that Safari does not automatically handle this situation like it's counterparts.
Edit3: More proof! A quick google search revealed lots of people on Safari have complaints about getting signed out of facebook randomly. Facebook also has pop up balloon warnings that notify you about important instances such as walking away from a half written message. I get logged out every time that balloon warns me! It's like a tough bouncer for Safari. What is going on here?
Okay, here's the solution, if you are running Safari 5.0.5 UPDATE NOW! 5.0.5 is junk. Call this a coincidence but for me this has reenforced the age long cliche about Apples inability to develop good software.
