object.description [= stringExpression]

Arguments

object

Required. Any instance of an Error object.

stringExpression

Optional. A string expression containing a description of the error.

Remarks

The description property contains the error message string associated with a specific error. Use the value contained in this property to alert a user to an error that you can't or don't want to handle.

The following example illustrates the use of the description property:

try
   x = y   // Cause an error.
catch(var e){   // Create local variable e.
   document.write(e)   // Prints "[object Error]".
   document.write((e.number & 0xFFFF))   // Prints 5009.
   document.write(e.description)   // Prints "'y' is undefined".
}
