object

Required. Any instance of an Error object.

stringExpression

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

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:

	Copy Code
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". }
