Using the jsLint tools I provided in my previous post you can add simple checking of an active file within Visual Studio. It also allows you to double click on an issue and go to the corresponding line. Here's a step by step guide.
Choose External Tools from the Tools menu
Click Add and enter the values given in the example below just replacing the command path to point to where you downloaded the example files from the previous post. Ticking Use Output window will make the commandline output show in the Visual Studio output window.
The results will be sent to the Output window.
You can double click on any result and Visual Studio will send you to the offending line.
/*global juxtapo,window,console */
Hope this helps
