Solution 1

Yes, use IE "Developer Tool" to debug and when working with FireFox download and activate FireBug plugin which is also great for debugging, DOM model inspection and CSS rule inspection.
Of course you can also debug JS code with VS debugger when testing your web application.

Solution 2

No need to write alert everytime.

Just put debugger; before the line you want to start debug.

And Set debugging in IE enabled.

before the line you want to start debugging, when compilation will hit that line it will take you to the source to debug it line by line as you're doing in Visual studio.
