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