Is there a way to configure RubyMine 3.1 to only use two spaces to indent JavaScript?

If you need to adjust indentation settings, in the Settings/Preferences dialog ( Ctrl+Alt+S ), go to Editor | Code Style. On the appropriate language page, on the Tabs and Indents tab, specify the appropriate indents options and click OK.
Spacing and indentation should be consistent throughout your code. Many developers choose to use 4-space or 2-space indentation. In JavaScript, each nested statement (e.g., a statement following a "{" brace) should be indented exactly once more than the previous line's indentation.
In IntelliJ IDEA, to convert existing tabs to spaces or vice versa, use File → Edit → Convert Indents → To Spaces (or To Tabs). The Reformat code shortcut Ctrl + Alt + L will also do this, while applying other changes.
Press Ctrl+Alt+S to open the IDE settings and select Editor | Code Style. Select the Detect and use existing file indents for editing checkbox. Apply the changes and close the dialog.
Which version of RubyMine are you using?
The JetBrains site of reference for v3.1 reads as follows:
Settings dialog -> Project settings -> Code style -> General -> Indent
Indent:
In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted for each indent level.
As for altering this specifically for Javascript, I don't see a possible solution - or at least not an easy one. You might be able to configure these general settings per file type, however. But I'm no expert in this field.
