Adds target attribute binding as 'linkToNewTab' helper

gistfile1.txt

// Extend Ember.LinkView to support target attribute binding
var NewTabLinkView = Ember.LinkView.extend({
  // Bind target attribute to view
  //attributeBindings: Ember.LinkView.prototype.attributeBindings.concat('target'),
  attributeBindings: ['href', 'title', 'target'],
  // Set target attribute to '_blank' by default
  target: '_blank',
  // Since we are navigating to a new browser instance (bypassing router), we can
  // just let browser do its default thing
  _invoke: function() {
    return true;
  }
});
