Description Jonathan Hurshman 2009-03-13 10:43:50 PDT
Changing the location hash on a frameset causes the frameset to reload. This occurs whether the hash is changed manually or programmatically by setting window.location.hash.

Firefox and IE do not exhibit this behavior; neither non-frameset pages nor frameset pages reload when the hash is changed.

This is troublesome for trying to maintain state by setting the hash.

Reduction is available at http://pilgrimwebdesign.com/changehash.html. This is a frameset containing only one frame. That frame displays new Date().getSeconds(). It also kicks off a timeout for 5 seconds to set the top's hash value. The result in WebKit is that the whole page reloads every 5 seconds, and one can observe the value displayed in the frame changing. In Firefox and IE, no reload happens.

I have reproduced this in the current nightly, in Safari 3.1.2, and in Chrome.

Same problem here. Frameset based page, using hash to navigate. Safari and chrome doesn't work properly. Though sometimes there is a workaround but overall it increases the development and maintenance time.

Best Regards

Display the reload event when the location.hash is changed.

Same bug here.
Is it possible to assign this light bug to somebody ?

The current behaviour is caused by FrameLoader::shouldScrollToAnchor
in WebCore/loader/FrameLoader.cpp.

Scrolling to an anchor is explicitly excluded for a frameset, the reason is given in the comments: "we don't want to just scroll if a link from within a frameset is trying to reload the frameset into _top."

In Firefox a link from within the frameset can reload the frameset, but only as long as the link contains no hash.

ie   <a href="index.html" target="_top">Reload!</a>
will reload the frameset

but  <a href="index.html#" target="_top">Reload!</a>
will not.
