Install JavaScript plugin in Android Studio

I'm running Android Studio version 0.3.7 on OS X 10.9. When I opened a JavaScript file I received a prompt saying: Plugin supporting files with *.js are found with 2 options: install plugins and ignore plugins. When I click the install option, a new Choose plugins to install or Enable window pops up, but it's empty, and only "nothing to show" is written. Has anyone experienced this? Is there a way to manually search and install these JavaScript plugins?
