Rails3: open link in new window

I'm having trouble writing the required javascript to open a link in a
new browser window in Rails3.

Previously, in rails2.3.x I could just do:

    link_to "foo", foo_path(foo), :popup => true

But now in Rails3, this option has been deprecated and the only other
way I can imagine doing this would be to use link_to_function but that
has also been nuked so I can't figure this out.

Can anyone give me some pointers please?


PS: I'm specifically looking to open a new browser-window, as opposed
to a modal-box or a jquery dialogue as I need it to stay alive whilst
the user continues to browse the site...

Another option is to use the Rails 3 unobtrusive way of event delegating those links:

  • Add an attribute “data-popup” to your link_to if you want it to open in a new window

With the jquery adapter, add to application.js inside the document ready handler:

$(‘a[data-popup]’).live(‘click’, function(e) {




With the prototype adapter, use this code inside the document ready handler:

  document.on("click", "a[data-popup]", function(event, element) {

    if (event.stopped) return;




Rails 3 has been all about separating content from behavior and falling back to target _blank is like bragging about how economic your brand new car is on paper and then driving it with the rev all the way into the red zone all the time.

hey, never noticed this reply~ I ended up installing the
prototype_legacy helper plugin and good old link_to_function to fix
the problem but I really do prefer your suggestion so I will give that
a go - thanks a lot. steve

I had to add [0]

otherwise it didnt work.

Good luck Dave

$('a[data-popup]').live('click', function(e) {
