Loop to reload data from each store in ExtJS Sencha

Question

I have 3 or more stores (A,B,C) which I want to reload with passed parameters. Can I use a loop to reload all of them?

 onClickRefreshButton: function() {       
    Ext.getStore('A').reload({
        params: {
            FirstParameter: 123,
            SecondParameter:456,
            ThirdParameter: 789,
        }
  });

Answer 1

Of course. Why not?

myArrayStores.forEach(st => { st.reload(); });

Answer 2

Here you have a fiddle that does what you need:

In my previous solution, I forgot to specify the scope:

 myArrayStores.forEach(st => { st.reload(); }, this);
