Class DOMException

DOM operations only raise exceptions in "exceptional" circumstances, i.e., when an operation is impossible to perform (either for logical reasons, because data is lost, or because the implementation has become unstable).

Attribute Description Property Type Readonly Description code Number true An integer indicating the type of error generated. message String true An exception message. Method Returns Description Event B C Interface Description Pseudo-class Description Constant Value Description 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 an XML name. 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 Level 3 Validation]. TYPE_MISMATCH_ERR 17 If the type of an object is incompatible with the expected type of the parameter associated to the object.
