IE8 javascript debugger

Is it possible using IE8 javascript debugger from ie8 dev tools to debug javascript on a page that runs locally from within VS2008 or you would have to run the page 开发者_运维知识库on a server against iis? Currently I am getting an error "Unable to attach to process" if I try to debug javascript on a local page.

The problem you are experiencing is due to the fact you most likely already have a debugger attach to the process running the web application. You will have to stop the other debugger, most likely VS, and then you will be able to attach the client JavaScript debugger.

I suggist IE Developer tool bar for IE

it will help you debugging JavaScript just from your IE browser

also for FireFox you can use firebug

and for your question i think you must be in your server to debug your staff from vs2008

There are couple of things you should do in order to debug from Visual studio.

General the below tip is the thing I always used to forget.

First enable debugging in IE: go to Tools > Internet Options > Advanced, and make sure “Disable Script Debugging (Internet Explorer)” is unchecked and “Display a notification about every script error” is checked.
