Is there any way to read a plist config file and access it like NSMutableDictionary?

cocos2d-x JavaScript

I’m new to cocos2d-x jsb. Is there any way to read a plist config file and access it like NSMutableDictionary?
I’m trying to use this method:
var config = cc.FileUtils.getInstance().createDictionaryWithContentsOfFile(“res/SlotMachine.plist”);

But it reports an error:Cocos2d: JS: /Users/selfcreator119/Library/Application Support/iPhone Simulator/7.0/Applications/59106587-C774-4A98-87B6-743DAB78E90B/test.app/src/myApp.js:88:TypeError: cc.FileUtils.getInstance(…).createDictionaryWithContentsOfFile is not a function
