application.controller.js

import Ember from 'ember';

export default Ember.Controller.extend({
	showHref: false
});

application.template.hbs

<p>The link has no href attr which is correct.</p>
<p>Now try toggling the href attr.</p>


<p>
	 → <a href={{if showHref "" null}}>Link</a> ←
</p>

<p>
	<label>
  	{{input type="checkbox" checked=showHref}}
    toggle href attr
  </label>
</p>
