Constructor
new SyntaxError( )new SyntaxError(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 SyntaxError object.
Returns
A newly constructed SyntaxError 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 SyntaxError( )
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 SyntaxError objects inherit the value “SyntaxError” for this property.
Description
An instance of the SyntaxError class is thrown to signal a syntax
error in JavaScript code. The eval( )
method, the
Function( )
constructor, and the RegExp( )
constructor may all throw exceptions of this type. See
Error for details about throwing and catching
exceptions.
