I still don't understand how pushState plays into this. And the example doesn't use pushstate so it doesn't help with answering that question. Note that pushState also should update the page's baseURI. But yes, <base> can easily mess up all your #foo links. / Jonas >> >> >> / Jonas >> >> > On Wed, Jul 10, 2013 at 7:11 AM, Igor Minar <iminar@google.com> wrote: >> > >> >> The current url resolution as >> >> described< >> >> http://www.whatwg.org/specs/web-apps/current-work/#resolving-urls>in >> >> the spec results in some unhelpful behavior when the following >> >> combination of web technologies are used in a client-side web app: >> >> >> >> - a combination of path-relative urls (<a >> >> href="relative/url/to/somewhere">link</a>) and fragment/anchor urls (<a >> >> href="#anchorUrl">link</a>) >> >> - history.pushState - used for deep-linking >> >> - base[href] - used to properly resolve the relative urls to the root >> >> of >> >> the application in various deployment environments >> >> >> >> >> >> Once history.pushState is used to change location.href, the >> >> path-relative >> >> urls resolve correctly as expected against the base[href], but anchor >> >> urls >> >> that are only useful if resolved against the current document.baseURI >> >> also >> >> unsurprisingly resolve against the base[href].
