I'm trying to get the URL and document title from the topmost Safari document/tab. I have an AppleScript and an objective-c version using Apple's Scripting Bridge framework.
Both versions work fine for most web pages, however when I open a Youtube video in full-screen mode, the Scripting Bridge based version fails. The Apple Script works fine for "normal" and full-screen Safari windows.
Can anyone see what is wrong with the Scripting Bridge code below to cause it to fail for full-screen Safari windows?
Here the code (I omitted error checking for brevity):
AppleScript:
tell application "Safari"
# Give us some time to open video in full-screen mode
delay 10
do JavaScript "document.title" in document 0
end tell
Scripting Bridge:
SafariApplication* safari = [SBApplication applicationWithBundleIdentifier:@"com.apple.Safari"];
SBElementArray* windows = [safari windows];
SafariTab* currentTab = [[windows objectAtIndex: 0] currentTab];
// This fails when in full-screen mode:
id result = [safari doJavaScript: @"document.title" in: currentTab];
NSLog(@"title: %@", result);
Scripting Bridge error (with added line breaks):
Apple event returned an error. Event = 'sfri'\'dojs'{
'----':'utxt'("document.title"),
'dcnm':'obj '{ 'want':'prop',
'from':'obj '{ 'want':'cwin',
'from':'null'(),
'form':'indx',
'seld':1 },
'form':'prop',
'seld':'cTab' }
}
Error info = {
ErrorNumber = -1728;
ErrorOffendingObject = <SBObject @0x175c2de0:
currentTab of SafariWindow 0 of application "Safari" (238)>;
}
I could not find details about the given error code. It complains about 'currentTab' which shows that the JavaScript event at least made it all the way to Safari. I assume that the current tab receives the event, but refuses to run the JS code, because it is in full-screen mode. However, why does this work for an AppleScript? Don't they use the same code path eventually?
Any suggestions are greatly appreciated. Thanks!
