Is it possible to check if a phone number hyperlink is supported by a browser? EG: Check if
<a href="tel:555555555">Call us on 555555555</a>
will work.
I'm trying to avoid the "Cannot open page. Safari cannot open the page because the address is invalid." type messages on things like iPod/iPad etc.
Thanks.
On desktop Skype uses the "callto:" spec instead of "tel:"
I think you could use css for this.
Just add some @media rules:
.telClass { display: none; }
.callToClass { display: block; }
@media only screen and (max-device-width: 480px) {
.tel-class { display: block; }
.call-to-class { display: none; }
}
Then you could define two elements in html:
<a href="tel:555555555" class="tel-class">Call us on 555555555</a>
<a href="callto:555555555" class="call-to-class">Call us on 555555555</a>
For a more complex code you could add some javascript code to check if the device is a handheld one:
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
var callToArray = document.getElementsByClassName('call-to-class');
callToArray.forEach(function(c) {
c.parentElement.removeChild(c);
});
}
Also there is a nice answer here by ghepting on how to to detect if skype is installed or not.
