This API is available on Firefox OS for internal applications only.
The onerror
event handler of the TelephonyCall
interface is a reference to a function to be called when the call does not succeed due to error. This is being obsoleted as it is very similar to TelephonyCall.ondisconnected
, but semantically more narrow and therefore not as useful.
The event handler is called with a CallEvent
as its only parameter.
Examples
// Telephony object var tel = navigator.mozTelephony; // Place a call tel.dial("123456789").then(function(call) { call.number; call.onerror = function(e) { console.log('Your call has failed with an error ' + e.call.error); } });
