What is the best way to declare variables which are available through out controller

[webfriend13]

Hi all,

I want to declare some variables which should be accessible through-out the controller. Right now I am using 'statics' section to declare such variable. Please let me know if there is a better or easier way to declare such variables?

Ext.define('MyController',
{
    extend: 'Ext.app.Controller',
   
   
    statics: {
        variableOne: '',
        variableTwo: ''
      
    },
    init: function () {
        this.control({
            'myView #my-grid': {
                select: this.onSelect
                    },
           ''myView #myRadio': {
                change: this.onRadioChange
            }
        });
    },
 
    onSelect: function (grid, record, index, eOpts) {
        this.self.variableOne = 10;
    },
   onRadioChange: function (rdBtn, newValue, oldValue, eOpts) {
       //Accessing go
        var val = this.self.variableOne;
  }
});
