The dialEmergency() method of the Telephony interface dials an emergency phone number and returns a new TelephonyCall object representing the new call.
Syntax
The new syntax is promise-based, and resolves with the TelephonyCall object for the new call:
myTelephony.dialEmergency(number,serviceId).then(function(myTelephonyCall) {
// do something with the new call
});
The original syntax (Firefox 1.3 and below) was just a regular non-promise method.
var myTelephonyCall = myTelephony.dialEmergency(number,serviceId);
Parameters
number- A string indicating the emergency number to dial.
serviceId Optional- The
idof the mobile service you want to use to make the call. If not specified, the default value for the device is used.
Returns
A promise that resolves with a TelephonyCall object.
Examples
// Telephony object
var tel = navigator.mozTelephony;
// Place a call
tel.dialEmergency("911").then(function(call) {
call.id;
});
