External div in new tab

Hi is there any way to open external divs in new Link.

The current code is :-

Discourse.ExternalNavItem = Discourse.NavItem.extend({
        href : function() {
            return this.get('href');
        }.property('href')
    });
 
Discourse.ExternalNavItem.create({href: wordlisturl, name: 'mywordlist'});

But i want to open the link in new tab. How can we add target="_blank".

Any help will be appreciated. Thanks in advance.
