import Ember from 'ember';

export function someHelper(params/*, hash*/) {
  switch(params) {
    case 'a':
     return { a:21,b:22 }
     break;
    case 'b':

     break;
    default:
     return { a:2,b:211 } 
  }
}):

And this is a hbs template

<p>{{some-helper object.foo}} </p>

how to get the value from ember helper that return object to my hbs template??

Answer 1

You can use the get helper provided by Ember; see the api reference . I modified your helper and used get helper in the following twiddle to illustrate you the usage. By the way, params passed to helper is an array so I got the first item (0 index) from the array for the switch case you have provided. See application.hbs to see get helper in action. My best regards.
