Code for Call Button from WebViewer

[PAE]

I managed to make calls from the webviewer with the setWebViewString block but I wonder if the html code is correct or can be improved.

Here is the html:

       <p><button type="button" name="911" onclick="callFunction(this)">Call 911</button></p>
       <p><button type="button" name="999888777" onclick="callFunction(this)">Call TEST</button></p>

<script>
        function callFunction(boton) {
        window.AppInventor.setWebViewString('tel:' + boton.name);  
        }
</script>

And the blocks from AppInventor:

Thank you very much .

why don't you use the PhoneCall component instead?

Thanks Taifun for your answer. I have learned a lot of things from your tutorials. 

I do not use the component PhoneCall because my project requires that the application does not ask for permission to make phonecalls. And secondly my project uses .gifs images and text with format, so I decided to use html and js from the webviewer. I wonder if this is the proper way to use buttons from html and call functions in app inventor blocks or if there is other way to achieve it.

my project requires that the application does not ask for permission to make phonecalls.

if it works, it's fine, but I think you will have to add the phone call permission manually in the manifest using e.g. AppToMarket... did you already built the app and try to run the apk file?

Ok, thank you Taifun. Yes, it works. Should I set the permission although the button in the html only opens the android call application with the phone number? The user can decide whether or not to call because it does not make the phone call directly. 

[Taifun]

if you do not need the permission, I would not set it

Taifun

btw. the phone call component can start a phone call directly
