Telephony.dialEmergency()
This API is available on Firefox OS for internal applications only.
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:
JavaScript
Copy Code
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.
JavaScript
Copy Code
var myTelephonyCall = myTelephony.dialEmergency(number,serviceId);
Parameters
number
- A string indicating the emergency number to dial.
serviceId Optional
- The
id
of 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
JavaScript
Copy Code
// Telephony object var tel = navigator.mozTelephony; // Place a call tel.dialEmergency("911").then(function(call) { call.id; });
