Error
Core JavaScript 1.5; JScript 5.5; ECMA v3
Predefined exception types
Inherits From: Object
Constructor
new Error( message ) new EvalError( message ) new RangeError( message ) new ReferenceError( message ) new SyntaxError( message ) new TypeError( message ) new URIError( message )
These constructors create an instance of the Error class or of one of its subclasses. The message argument is optional.
Properties
Error and all of its subclasses define the same two properties:
message
An error message that provides details about the exception. This property holds the string passed to the constructor, or an implementation-defined default string.
name
A string that specifies the type of the exception. This property is always the name of the constructor used to create the exception object.
Methods
toString( )
Returns a string representation of the Error (or subclass) object.
