Debugging Active Script

The Active Script debugger enables you to detect and diagnose errors in code that contains Active Script (such as client-side JavaScript) or Active Script objects. With the debugger, you can control the execution of Active Script by setting line breakpoints, suspending launches, stepping through your code, and examining and changing the contents of variables.

With the Active Script debugger, you can debug the following file types:

• Script:
  JavaScript, or files with extension .js.
  • VisualBasic script, or files with extension .vbs.

• HTML files ( .htm or .html) with the following types of embedded script:
  • JavaScript
  • VisualBasic script

• JSP files ( .jsp) with the following types of embedded script:
  • JavaScript

  • VisualBasic script
