JavaScript 1.5; JScript 5.5; ECMAScript v3 Inherits from Error

Constructor

new RangeError(  )
new RangeError(message)

Arguments

message

An optional error message that provides details about the exception. If specified, this argument is used as the value for the message property of the RangeError object.

Returns

A newly constructed RangeError object. If the message argument is specified, the Error object will use it as the value of its message property; otherwise, it will use an implementation-defined default string as the value of that property. When the RangeError( ) constructor is called as a function, without the new operator, it behaves just as it does when called with the new operator.

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. See Error.message for details.

name

A string that specifies the type of the exception. All RangeError objects inherit the value "RangeError" for this property.

Description

An instance of the RangeError class is thrown when a numeric value is not in its legal range. For example, setting the length of an array is set to a negative number causes a RangeError to be thrown. See Error for details about throwing and catching exceptions.
