IntelliJ: how to force editor to treat a file as javascript?

Question

I\'m creating a Grails app in IntelliJ 10 and have a javascript file that is created dynamically, as a Grails view.

For that reason the javascript file doesn\'t end

Answer 1

You can add additional extensions to the JavaScript in Settings (Preferences on Mac) | File Types.

See also Settings | Template Data Languages where you can configure certain files in the project as templates producing specified language to get proper code completion.

Answer 2

The above answer is slightly outdated. You can do the same in IntelliJ 14 by doing the following:

1. Go to Preferences (Mac OSX : Cmd + Comma)
2. Under Editor -> File Types
3. In the Recognized File Types Highlight JavaScript files (JavaScript)
4. Under Registered Patterns press the + button
5. Enter your regex pattern (for example: *.js.scala.html) and press OK

Cheers!
