Debug JavaScript/VB Script programs (ASP)

In the Article debugging JavaScript/VB Script script Program ( wscript ) some netizens asked me how to debug Asp inside the foot In this program, I don't know if he is asking for debugging Asp VBScript ASP Code , or Asp. net JavaScript/VBScript client code in the webpage, so in this article, I will first debug Asp the Asp code in the webpage can be explained in this case.

estimation Asp there are very few people playing this game, but many old websites still use Asp for technical production and maintenance, you still need to debug and modify the Asp webpage code. Although Asp most of the webpage code is VBScript or JavaScript , many DHTML the code is also written in JavaScript/VBScript , which can easily mislead programmers, the two are both running on the browser, but they are not.

ASPWebpage code runs on the server, specificallyIISWhy?IISCan be executed simultaneouslyASPWebpage andASP. NETWebpage code, if I tell youIISYou can also executeJSPCode, do you believe it? Of course,IISHow to executeASP,ASP. NETAndJSPYou can open a series of articles to explain the code.

WhileDHTMLThe code is on the browser side (IEOrFirefox). Different execution methods of the two codes determine different debugging policies.

To sum up, the two are different things, but they complement each other and are inseparable ......

For debuggingASPWebpage code, you need to debugIISWorker Process (notIISADMINThat process), inIn IIS 6.0Medium,IISThe workflow name isW3wp.exe(World Wide Web process), InIn IIS 6.0It seems likeDllhost.exe. BecauseIn IIS 5.0There are not many users.-The main reason is that I don't need it anymore, so this article usesIn IIS 6.0As a platform.
