I am trying to allow user call in mobile phones as in
1-408-555-5555
such that when user press the link, then it not only opens the number for calling but actually makes the call too at the same time (aka saves user one step to press button).
Also I need to add an extra code number (lets say 2525 ) dialled when call is connected. Is that possible? This is HTML5 website.
The function of clicking the link will depend on the platform, so this cannot be changed in your code. Most platforms such as iOS do not connect to the number without confirmation as a security measure.
To add the extra code number once the call has been connected, try using the p.
<a href='tel:14085555555p2525'>1-408-555-5555</a>
However I haven't tried this so I'm not sure whether this will work.
You have to access the dialler functionality of the phone which is not possible and as per mobile OS are considered they wont allow it due to security measures.

I want to create a web app(for practicing my skills) that will help in conducting online exams. So I want to ask that is there any way to find out the following things---
Is there another page opened in the chrome (if yes then which)
Is there is another application running in the background (if yes then which)
Is user switching between tabs/applications/desktops etc.
Basically, I just want to create an app that just keeps track of users' activity when the user is giving an exam.
And if you have any of the solutions to the above problems then please tell.
Since most things you want to access are considered private data, it is not directly possible in a Web App, except the page visibility. But you can write a browser extension, which is at least allowed to access data within the browser. For information beyond the browser you should consider a native application or some embedded solution like React Native, Xamarin, or Electron, to name a few.
To get the info if the user is currently using the tab your Web App is running in, use the Page Visibility API:
https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API
For accessing information about other tabs and browser internal stuff, write an extension:
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API
I have the following case in a web application of mine. The usual browser that the user uses is Chrome.
I use digital certificates that users have cryptographic cards that they insert into a card reader.
To log in to the application, basically users access the https link that makes the certificate data read.
So far everything works fine.
If the user to end his session of the application closes the browser, there is no problem. Everything is over.
But if the user wants to leave his application session, without closing all browser windows, here are my problems.
There is a button that closes the session of the application, the user leaves and redirects to the initial login screen. It seems that everything has been reset, because the user has left. But when the new user wants to log in and press the link to read the certificate data, instead of doing a new reading of the new card, use the data from the previous card without just asking for the pin to access it.
The problem goes further, for example, if the user has forgotten the card, the card and tries to logarize, the failure to read the certificate. But now, although inserted correctly, the card will not be read again until the browser is restarted, which maintains a cache that does not have a certificate.
At the moment only the solution was found by closing all Chrome windows, but that depends on whether the user does or not.
A partial solution would be sure to close the browser with javascript () but for some time, it can not be closed with javascript (window.close ()), a window that can not be opened from the site itself, with what is available I think it's ruled out
Can someone contribute to me? Thank you
Chrome and the rest of browsers maintain a cache of the SSL authentications performed and decide when to prompt user for selecting a certificate. There is no "logout" function neither the connection can be closed from server side due to TLS resumption protocol ( client can resume the session)
This a common and known issue when defining an authentication system using client certificates. I only have found a workaround: use different domains to force browser to choose a certificate:
login.domain.com
-->login1.domain.com
-->login2.domain.com
-->loginN.domain.com
You have a virtual authentication URL login.domain.com which redirects user's browser to a random loginN.domain.com every time you need an authentication. Chrome will detect that it is a different domain and will prompt user for selecting a certificate
You could also think about using different ports instead of different DNS, but then you could have problems with the user's firewall because you are not using a standard port, and in this case Firefox does not show the window either.
I'm working on an AIR app that logs a user in to a remote website. At certain points during the session the user may need to open a page in their browser. When they do that they are not logged in according to the browser so the user must login again. I'm trying to login them in through the browser when they login in the application.
I've read that AIR can manage cookies. I think it's doing that but I'm not sure. Is there a way to share cookies with the browser? Is that what manage cookies setting does?
If none of that is happening could I create a mx:HTML instance or stage web view and double login with that? A stage webview should be using the system browser correct? The same browser that will launch when navigateToURL() is called.
UPDATE:
It looks like cookies are shared across browsers except in a few cases such as Firefox and Linux. Update again, cookies are shared less often than initially thought. It looks like I might be able to login a user by creating a StageWebView instance. I will have to double check to make sure it's a default browser and not the internal webkit.
UGH. It looks like StageWebView on the desktop uses the internal webkit. There is a useNative property though. But even if I can use a native system browser I'm not sure how to log someone in with it because I don't think I can post to it? I think I can only set the URL which would be a get...
...It looks like I can create a post request and then use navigateToURL() to load that request. It would be hacky but it might work.
ARG. It looks like AIR doesn't support post through navigateToURL().
I don't know why you want to complicate things by thinking just to use POST ?! You can use GET by sending some temporary identifier ( token, hash, ... ), like some websites do with their user's newsletter when they give you the possibility to log in just by clicking a simple link in that newsletter, which will be generated by your server side script after that your user has been successfully identified, then when the user opens that link in the browser you can verify that information and then create your cookies ...
Hope that can help.
In Windows Phone, the reminder is usually used for scheduled notifications. The reminder when popped up, requires user to click the reminder pop up in order to navigate to specific page and do certain action.
Can we simulate or suppress this reminder programatically when occured and instead perform the action it was supposed to execute when actually clicked. This would be of great use to user.
Any help, suggestions or ideas on the same?.
Thanks In Advance.
It isn't possible. A Windows Phone application has very limited interaction with the system when it isn't running in the foreground.
If you're trying to bypass the reminder to display something (for instance, a page of your application) without user interaction, then you have no way of doing that.
If it's just about updating some data or calling a webservice without displaying anything, you should use a background agent instead of a reminder.
Windows Phone was built around the idea of letting the user in control at all time. That's why there is no way of forcing the user to navigate to a page of your application if it wasn't running in first place.
I try to get a google spreadsheet to open my phone numbers in cell F as callto:// links, so that my voip-software can instantly call this number.
Unfortunately writing callto://number into the cells makes the spreadsheet guess that, the link is http:/callto://number.
So I tried to implement a UI, that reads the number from the cell and issue a window.open, but that is not possible.
Then I tried to put this callto://-link into an anchor element, but that doesn't work either. I also tried to use setHTML but, that doesn't work.
Any ideas how I can get this problem solved?
I customised an existing workflow to work for this purpose and it works really well. It is using the Mac application Alfred (requires the paid-for Powerpack) to use. The workflow consists of a few parts:
Highlight/select the number inside Google Sheets (or any other app)
Fire the keyboard shortcut assigned to the Alfred workflow.
The workflow copies the number into the clipboard.
It escapes any extraneous characters to make it a usable phone number.
It prepends the text snippet tel:// to the number. The workflow can easily be adjusted to use callto://
It executes the "link" that has been built.
FaceTime launches automatically to call using your nearby connected iPhone using Mac's handoff feature. If you use call to links, it may open Skype or other VOIP apps assigned to handle the links natively.
If you like the idea, you may download my workflow and give it a go.
