    Telephony.oncallschanged

    Non-standard
    This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

    This API is available on Firefox OS for internal applications only.

    The oncallschanged property of the Telephony interface specifies an event listener to receive callschanged events. These events occur when the list of ongoing calls, as indicated by Telephony.calls, changes.

    Syntax

    myTelephony.oncallschanged = function() { ... };
    

    These events are of type CallEvent.

    Examples

    // Telephony object
    var tel = navigator.mozTelephony;
    
    tel.oncallschanged = function() {
      // When call list changes, do something
    };
