Question

I’ve got this model with a static enumeration set

Ext.define('MyApp.model.RefreshableComponent', {
   statics: {
      RefreshIntervals: {
         ONEMIN: 1,
         FIVEMINS: 2,
         TENMINS: 3,
         FIFTEENMINS: 4,
         DEFAULT: 5
      }
   }
});

and I’m accessing it in another class like so

updateDefaultTask: function () {
   this.updateTask(MyApp.model.RefreshableComponent.RefreshIntervals.DEFAULT);
},
updateTask: function (refreshInterval) {
      var components = this.getVisibleComponentsByRefreshInterval(refreshInterval);
      if (this.debugMode) {
         console.log("REFRESHMANAGER: Triggered the update task " + refreshInterval);
      }    
   },

I would like to display the name of the refreshInterval in the log, not the int value. How can I go about this?

I’m open to defining this enumeration in a different way, as long as I can still pass in the name as a parameter, rather than the int, for readability reasons.

Ext has the Ext.Object.getKey() method:

Returns the first matching key corresponding to the given value. If no
matching value is found, null is returned.

var person = {
    name: 'Jacky',
    loves: 'food'
};

alert(Ext.Object.getKey(person, 'food')); // alerts 'loves'
