Confluence: How to force links to open in a new window

A free plugin is available that reproduces some of this functionality.

Purpose

By default, links are opened in the same window. To force them to be opened in a new window, follow these steps:

Workaround

This customisation will only work for Confluence 3.0.1 and above

1. Visit Administration >> Custom HTML
2. Click Edit
3. In the At end of the HEAD field, insert this code:
   • For external links only, like [http://www.google.com]:<script> jQuery(document).ready(function() { jQuery(".external-link").attr("target", "_blank"); }); </script>
   • For all type of links (internal and external):<script> jQuery(document).ready(function() { jQuery(".wiki-content a").attr("target", "_blank"); }); </script>
4. Hit Save

If you’d like to use this functionality on a single page rather than the whole instance, enable the HTML Macro and embed this script in your page.
