Debug Object


An intrinsic global object that can send output to a script debugger, such as the Microsoft Script Debugger.


The Debug object cannot be created directly, but it is always available for use.

The Write and WriteLine methods of the Debug object display strings in the Immediate window of the Microsoft Script Debugger at run time. If the script is not being debugged, the methods have no effect.

This example uses the Write method to display the value of the variable in the Immediate window of the Microsoft Script Debugger.


To run this example, you must have a script debugger installed and the script must run in debug mode.

Internet Explorer 8 includes the Microsoft JScript debugger. If you are using an earlier version of Internet Explorer, see How to: Enable and Start Script Debugging from Internet Explorer.
