How to read values from properties file in ExtJs

Question

I want to read values from config.properties and use these values in my ExtJs ComboBox . I do not want to read from JSON file.

Where should I place the config.properties file? Should I place it in the webcontent directly? I do not want to hard code the path/ or at least reduce it.

And how can I access property values through JavaScript.?

Thanks

Answer 1

This is not ExtJS specific but in general rather applicable to javascript as a whole.

Best bet would be to either include it in a global file that gets included in your app and is namespaced appropriately to your app so as to minimise chance of collisions with any other potential variables

 MyApp = { config:{ property1:'something', property2:'something2' } } // Then you can access this anywhere you like myProperty1 = MyApp.config.property1; // assigns the string "something" to variable myProperty1

You can load the properties file into a data store, this way you can have the key-value pairs in the your properties file mapped to a simple model with fields key and value. And to enable your proxy to load data from the properties file and be converted into the corresponding model you'll have to create a reader that'll read the data from the properties file and convert to the desired record.

This custom package for i18n will give you some idea how to do that.
