// All navigation that is relative should be passed through the navigate | |

// attribute, bypass the delegation completely. | |
$(document).on("click", "a[href]:not([data-bypass])", function(evt) { | |
// Get the absolute anchor href. | |
var href = { prop: $(this).prop("href"), attr: $(this).attr("href") }; | |
// Get the absolute root. | |
var root = location.protocol + "//" + location.host + Application.root; | |
// Ensure the root is part of the anchor href, meaning it's relative. | |
if (href.prop.slice(0, root.length) === root) { | |
// Stop the default event to ensure the link will not cause a page | |
// refresh. | |
evt.preventDefault(); | |
// Note by using Backbone.history.navigate, router events will not be | |
// triggered. If this is a problem, change this to navigate on your | |
// router. | |
Backbone.history.navigate(href, true); | |

If href
is http://google.com
(not relative url), the previous will return google.com
while the later return http://

GitHub never notified me of any of these comments >_> I just updated the Gist to latest version I've been using.
Shouldn't it be href.attr
in the navigate function?
@XemsDoom yes it should
You also should probably add a check whether or not someone called preventDefault on the event.
