如何将（日期）对象传递给Ember车把帮手？

Question

How can I access a passed object in an Ember Handlebars helper?

Inside the helper 'date' is always undefined.

// date object
var date = new Date('2013-05-10T01:55:00+01:00');

// helper
Ember.Handlebars.makeBoundHelper('format', function(date) {
     return moment(date).format();
};

// template
{{format date}}

Answer 1

use registerBoundHelper not makeBoundHelper . makeBoundHelper doesn't take the helper name

// date object
var date = new Date('2013-05-10T01:55:00+01:00');

// helper
Ember.Handlebars.registerBoundHelper('format', function(date) {
     return moment(date).format()
};
