You need to keep those values in a global file which gets included in the app. Make sure to name it correctly to avoid conflict.
Something like-

JavaScript

MyApp = {
    config:{
            property1:'value1',
            property2:'value2'
          }
}

Then you can access these values like-

JavaScript

myProperty1 = MyApp.config.property1;

Hope, it helps :)
