IE View -> External Script debugger -> Open
Then you are prompted with dialog box with all the installed above applications select one of them and start debugging just like your normal code behind(C#) code or pressing keys f9/f10/f11 keys.
Alternatively you can set the below statements inline your code to debug.
The debugger statement can also be placed anywhere in your code to suspend execution this is similar to setting a breakpoint. The Stop statement is the VBScript version of JScript’s debugger statement
