message Property (JScript) 

Returns an error message string.



Required. Instance of Error object.

The message property is a string containing an error message 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 description and message properties refer to the same message; the description property provides backwards compatibility, while the message property complies with the ECMA standard.

The following example causes an exception to be thrown, and displays the message of the error.

function getAge(age) {
   if(age < 0)
      throw new Error("An age cannot be negative.")
   print("Age is "+age+".");

// Pass the getAge an invalid argument.
try {
} catch(e) {

The output of this code is:

An age cannot be negative.
