I'm running in the following problem. I use a webview as a built-in
webbrowser within my app. Given the fact that it is an iTunes like
applications I don't allow the opening of new windows. Instead when a
new window request comes in I just cancel it and open the requested
URL in the same window.
There's one situation however where this doesn't seem to work.
Take this webpage in Safari: http://ucelinks.cdlib.org:8888/sfx_local?sid=Entrez:PubMed&id=pmid:16636135
If you click on the first "Go" image/button labelled with "Highwire
press free" you'll notice a new window is created and a webpage is
loaded in there.
However I can't get the contents to load in the same window that the
original request came from.
The problem is in the way the links are created, they are in a form
that is triggered by a javascript when you click the link (don't ask
why!?!):
<form METHOD=POST ACTION="http://ucelinks.cdlib.org:8888/sfx_local/cgi/core/sfxresolver.cgi
" NAME="basic1" TARGET="newwin">
<A
HREF="javascript:openWin(this);window.document.basic1.submit();"><IMG
SRC="/sfx_local/img/sfxmenu/go.gif" BORDER="0" HSPACE="16" ALT="GO"></A>
In my delegate methods I have the following:
- (void)webView:(WebView *)sender decidePolicyForNewWindowAction:
(NSDictionary *)actionInformation request:(NSURLRequest *)request
newFrameName:(NSString *)frameName decisionListener:
(id<WebPolicyDecisionListener>)listener{
NSLog(@"New window request: %@, actioninfo: %@", request,
actionInformation);
//DO NOT ALLOW
[listener ignore];
//INSTEAD Open new window in this window
[[webView mainFrame] loadRequest:request];
}
What I get is that first method is called but with a NULL request. And
since the request is NULL I can't figure out when this is whole thing
is actually happening if the user also browses other types of pages.
The second method is not even called.
Now I can see kind of why, first the javascript will just create an
empty window, and then the second javascript should submit and
probably open the real link in that new window, I guess by referring
to it's frame name (or am I wrong?).
So the question is how to catch that call and how to redirect it to my
existing webview frame?
Many thanks for your help!
