ember.js Currency formatting template helper Creating a new helper
Example
Use Ember CLI to generate a new helper in your app:
ember generate helper format-currency
Then edit helpers/format-currency.js to contain the following:
import Ember from 'ember';
export function formatCurrency([value, ...rest]) {
const dollars = Math.floor(value / 100);
const cents = value % 100;
const sign = '$';
if (cents.toString().length === 1) { cents = '0' + cents; }
return `${sign}${dollars}.${cents}`;
}
export default Ember.Helper.helper(formatCurrency);
Now you can use {{format-currency model.someNumericValue}} in templates.
A unit test for the new helper is automatically created in tests/unit/helpers/
