I have configured a classNameBindings as follows:
classNameBindings: ["App.controller.value:class1:class2"]
However, I noticed that it is not functioning as expected. No classes are being added. Interestingly, when I eliminate the false value (i.e., :class2), class1 gets added only if App.controller.value evaluates to true. Is this a common problem with Ember or am I making an error in my implementation?
Can you be certain that there is something stored in App.controller.value?
Your attempted solution should work without any issues. However, keep in mind that by exposing an application global to your view, you run the risk of adding unnecessary complexity. You can refer to this JSFiddle example for clarification.
Below is the JavaScript snippet from the JSFiddle:
App = Ember.Application.create();
App.someGlobal = Ember.Object.create({
isEverythingOk: true
});
App.OkView = Ember.View.extend({
classNameBindings: ['App.someGlobal.isEverythingOk:class1:class2']
, templateName: 'ok'
});
