Summary
The onicccardlockerror property specifies an event listener to receive icccardlockerror events. These events occur whenever the unlockCardLock or setCardLock method fails.
Note: MozMobileConnection inherits from the EventTarget interface, so it's also possible to listen for events by using the addEventListener() method.
Syntax
navigator.mozMobileConnection.onicccardlockerror = funcRef;
Where funcRef is a function to be called when the icccardlockerror event occurs.
Specification
Not part of any specification.
