    Summary

    The RangeError object indicates an error when a value is not in the set or range of allowed values.

    Syntax

    new RangeError([message[, fileName[, lineNumber]]])

    Parameters

    message
    Optional. Human-readable description of the error
    fileName
    Optional. The name of the file containing the code that caused the exception
    lineNumber
    Optional. The line number of the code that caused the exception

    Description

    A RangeError is thrown when trying to pass a number as an argument to a function that does not allow a range that includes that number. This can be encountered when attempting to create an array of an illegal length with the Array constructor, or when passing bad values to the numeric methods Number.toExponential(), Number.toFixed() or Number.toPrecision().

    Properties

    RangeError.prototype
    Allows the addition of properties to an RangeError object.

    Methods

    The global RangeError contains no methods of its own, however, it does inherit some methods through the prototype chain.

    RangeError instances

    Properties

    RangeError.prototype.constructor
    Specifies the function that created an instance's prototype.
    RangeError.prototype.message
    Error message. Although ECMA-262 specifies that RangeError should provide its own message property, in SpiderMonkey, it inherits Error.prototype.message.
    RangeError.prototype.name
    Error name. Inherited from Error.
    RangeError.prototype.fileName
    Path to file that raised this error. Inherited from Error.
    RangeError.prototype.lineNumber
    Line number in file that raised this error. Inherited from Error.
    RangeError.prototype.columnNumber
    Column number in line that raised this error. Inherited from Error.
    RangeError.prototype.stack
    Stack trace. Inherited from Error.

    Methods

    Although the RangeError prototype object does not contain any methods of its own, RangeError instances do inherit some methods through the prototype chain.

    Examples

    Example: Using RangeError

    var check = function(num) {
      if (num < MIN || num > MAX) {
        throw new RangeError('Parameter must be between ' + MIN + ' and ' + MAX);
      }
    };
    
    try {
      check(500);
    }
    catch (e) {
      if (e instanceof RangeError) {
        // Handle range error
      }
    }
