Knockout observableArray in TypeScript

Question

What is the proper way to initialize a Knockout observableArray in a TypeScript class?

I am doing something like this:

   module ViewModel { 

        de         


        

Answer 1

I just did this in TypeScript 1.3 (though it should work in older versions too):

pendingAddAssociations: KnockoutObservableArray = ko.observableArray([]);

for your example, if you have an Agency class.

export class IndexPageViewModel {

        agencies: KnockoutObservableArray;

        constructor () {
            this.agencies = ko.observableArray([]);
        }
    }

I've also found that you can cast to any this.agencies = []; This is useful if you are using the Knockout ES5 plugin.
