ErrorSeverity

An integer indicating the severity of a DOMError.

Values

Value	Meaning
warning	The severity of the error described by the `DOMError` is warning. A `WARNING` will not cause the processing to stop, unless the call of the `DOMErrorHandler` returns `false`.
error	The severity of the error described by the `DOMError` is error. A `ERROR` may not cause the processing to stop if the error can be recovered, unless the call of the `DOMErrorHandler` returns `false`.
fatalError	The severity of the error described by the `DOMError` is fatal error. A `FATAL_ERROR` will cause the normal processing to stop. The return value of calling the `DOMErrorHandler` is ignored unless the implementation chooses to continue, in which case the behavior becomes undefined.
