Step 1:
Open an existing
asp.net application in Visual Studio 2003/05 if there is any, which uses
JavaScript or create a new demo application from scratch.
Step 2:
When we create a web project in Microsoft’s Visual Studio a
file in the name of web.config is created by default in the web project.
We need to check the following setting:
<compilation debug="false" strict="false" explicit="true" />
Then change the debug setting to “true” as in the following.
<compilation debug="true" strict="false" explicit="true" />
Step 3:
Open Internet Information Service (IIS). Here is how to open
IIS.
Start à Settings à Control Panel à Administrative Tools à
Internet Information Services
à Expand Web
Sites à Default Web Site à right click on your web project you want
to debug and click properties à
click Directory Tab à click
configuration à in the new opened
window click Tab Debugging and if two check boxes labeled “Enable Server Side
Script Debugging” and “Enable Client Side Script Debugging” are unchecked then
check those two check boxes. (Pl refer to Screen Shot 1)
Figure 1
Step 4:
Open the Internet Explorer browser, click on menu Tools à Internet Options à Advanced Tab à
if Disable Script Debugging (Internet Explorer) and Disable Script Debugging
(Other) check boxes are checked then uncheck those two check boxes and click button
OK. (Refer Screen Shot 2)
Figure 2
Step 5:
Now, open your web project in Visual Studio IDE. Select menu
Tools.
If you open the project in VS 2003 then under Tools menu
select attach a process and select aspnet process and attach the process to the
application.
If you open the project in VS 2005 then it does not require you
to explicitly attach the aspnet process. In the JavaScript add a break point
where you want to debug and also add a break point in the .vb or .cs code file
where the JavaScript function is called.
Step 6:
Run the project by clicking on icon Start. The application
will start and wait at the break point where you placed the break point.
