Telephony.ready
This API is available on Firefox OS for internal applications only.
The ready
read-only property of the Telephony
interface provides an asynchronous notification that the object is initialized.
This is useful because when a Telephony
object is created it takes some time to sync the information with the underlying hardware layer and fully initialize. If the code tries to read a value such as Telephony.call
before Telephony.ready
is resolved, the value may not be correct.
Syntax
myTelephony.ready.then(function() { // do something now telephony is initialized });
Value
A Promise
that resolves with void when the telephony object is initialised.
Examples
// Telephony object var tel = navigator.mozTelephony; tel.ready.then(function() { // ok, now let's make some calls });
