The debug.write function sends strings to the script debugger.


Debug.write([str1 [, str2 [, ... [, strN]]]])


str1, str2, ... , strN Optional
Strings to send to the script debugger.


The Debug.write function sends strings to the Immediate window of a script debugger at run time. If the script is not being debugged, the Debug.write function has no effect.

The Debug.write function is almost identical to the Debug.writeln function. The only difference is that the Debug.writeln function sends a newline character after the strings are sent.


This example uses the Debug.write function to display the value of the variable in the Immediate window of the script debugger.

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

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

var counter = 42;  
Debug.write("The value of counter is " + counter);
