Question

I’m in my applications controller and I have a url string. How do I tell the app to open the url in the browser in a new window. Is there a way to set the target to blank?

For example

def link
  @url = 'www.google.com'
  ****??? Open @url ?? *** with target blank?
end

Answer 1

This is not possible to do directly from the controller. Using redirect_to @url has the effect of opening an URL in the same “window”, as it simply sends a HTTP redirect instruction back to the browser. redirect_to is not capable of opening new windows. The controller resides on the server side, and opening a new window belongs to the client side.

Some options:

a) render a link with <%= link_to 'Google', 'google.com', :target => '_blank' %> or <a href="google.com" target="_blank">Google</a> which the user can click on in a new view

b) use JavaScript to open the link automatically, but beware that browsers may treat this as a popup and block it

By combining these options you can open links in new window for browsers/users who allow it, and fall back to a regular URL in case that didn’t work.
