First open Visual studio   select your project in solution explorer  Right click and choose option  quot browse with quot  then set IE as default browser   Now open IE   go to Tools  gt  gt  Internet option  gt  gt  Advance gt  gt  uncheck the checkbox having  quot Disable Script Debugging  Internet Explorer   and then click Apply and OK and you are done    Now you can set breakpoints in your JS file and then hit the debug button in VS    EDIT - For asp net web application right click on the page which is your startup page say default aspx  and perform the same steps

The debugger should automatically attach to the browser with Visual Studio 2012   You can use the debugger keyword to halt at a certain point in the application or use the breakpoints directly inside VS     You can also detatch the default debugger in Visual Studio and use the Developer Tools which come pre loaded with Internet Explorer or FireBug etc   To do this goto Visual Studio -  Debug -  Detatch All and then click Start debugging in Internet Explorer   You can then set breakpoints at this level

For debugging JavaScript code in VS2015  there is no need for    Enabling script debugging in IE Options -  Advanced tab Writing debugger statement in JavaScript code   Attaching IE didn t work  but here is a workaround   Select IE    and press F5  This will attach both worker process and IE as shown here-   If you are not interested in debugging server code  detach it from Processes window    You will still face the slowness when you press F5 and all your server code compiles and loads up in VS  Note that you can detach and attach again the IE instance launched from VS  JavaScript breakpoints are hit the same way they are in server side code
