ExceptionCode enumeration
An integer indicating the type of error generated.
* 
Other numeric codes are reserved for W3C for possible future use.
The ExceptionCode enumeration has the following constants of type unsigned short.
INDEX_SIZE_ERR = 1
If index or size is negative, or greater than the allowed value
DOMSTRING_SIZE_ERR = 2
If the specified range of text does not fit into a DOMString
HIERARCHY_REQUEST_ERR = 3
If any node is inserted somewhere it doesn't belong
WRONG_DOCUMENT_ERR = 4
If a node is used in a different document than the one that created it (that doesn't support it)
INVALID_CHARACTER_ERR = 5
If an invalid or illegal character is specified, such as in a name. See production 2 in the XML specification for the definition of a legal character, and production 5 for the definition of a legal name character.
NO_DATA_ALLOWED_ERR = 6
If data is specified for a node which does not support data
NO_MODIFICATION_ALLOWED_ERR = 7
If an attempt is made to modify an object where modifications are not allowed
NOT_FOUND_ERR = 8
If an attempt is made to reference a node in a context where it does not exist
NOT_SUPPORTED_ERR = 9
If the implementation does not support the requested type of object or operation.
INUSE_ATTRIBUTE_ERR = 10
If an attempt is made to add an attribute that is already in use elsewhere
INVALID_STATE_ERR = 11
If an attempt is made to use an object that is not, or is no longer, usable.
SYNTAX_ERR = 12
If an invalid or illegal string is specified.
INVALID_MODIFICATION_ERR = 13
If an attempt is made to modify the type of the underlying object.
NAMESPACE_ERR = 14
If an attempt is made to create or change an object in a way which is incorrect with regard to namespaces.
INVALID_ACCESS_ERR = 15
If a parameter or an operation is not supported by the underlying object.
VALIDATION_ERR = 16
If a call to a method such as insertBefore or removeChild would make the Node invalid with respect to "partial validity", this exception would be raised and the operation would not be done. This code is used in DOM Validation Specification. Refer to this specification for further information.
TYPE_MISMATCH_ERR = 17
If the type of an object is incompatible with the expected type of the parameter associated to the object.
