I have a question about getting the target frame specified in a HTML
link or similar action.
Background:
-----------
Given a web page consisting of several frame and iframe elements I
have a link in frame A which has the attribute target="B" set.
(Something like <a href="#" target="B">foo</a>.) I handle the link
myself by intercepting -
webView:decidePolicyForNavigationAction:request:frame:decisionListener:
in my delegate. I would like to get the frame (WebFrame*) specified
in the target attribue (the frame/iframe named "B") of the link so
that I can call loadRequest: on that frame to only reload that part
of the web page.
Problem:
--------
When I look at the actionInformation dict received in -
webView:decidePolicyForNavigationAction:request:frame:decisionListener:
I see that it contains a WebActionElementKey dict which contains
WebElementFrame and WebElementTargetFrame. According to common sense
and the somwhat sparse documentation I could find, the
WebElementTargetFrame should IMHO correspond to the frame designated
by the target attribute of the link. But it doesn't! It and
WebElementFrame as well as the frame parmeter of the method always
seem to point to the frame the link is in, not the one specified in
the target attribute.
Questions:
----------
Is this a bug in WebKit or am I doing something wrong or are my
expectations wrong? If it is not a bug why are there WebElementFrame
and WebElementTargetFrame entries in the dictionary and what is the
difference?
I have a couple of ideas how I can work around this problem in my
project but it would be much more elegant if I could get the targeted
frame directly from WebKit.
Ideas anyone?
Thanks!
Mike
