It seems OK, I added NSLog to both methods:

2005-12-02 13:26:08.000 DTRoot[19607] setJSInWebView: <HTML><HEAD><TITLE> </TITLE><SCRIPT type="text/javascript"></ SCRIPT></HEAD><BODY style="border: 0; margin: 0; padding: 0">loaded from -awakeFromNib</BODY></HTML> 2005-12-02 13:26:08.010 DTRoot[19607] windowScriptObjectAvailable 2005-12-02 13:26:08.016 DTRoot[19607] didFinishLoadForFrame 2005-12-02 13:26:08.016 DTRoot[19607] didFinishLoadForFrame: <HTML><HEAD><TITLE> </TITLE><SCRIPT type="text/javascript"></ SCRIPT></HEAD><BODY style="border: 0; margin: 0; padding: 0">loaded from -awakeFromNib</BODY></HTML> 2005-12-02 13:26:08.016 DataTypeRoot[19607] (null) result

It would be interesting to NSLog the result of the outerHTML call to see exactly what HTML you end up reloading. I suspect the result does not include the script you've constructed, which may indicate a bug in WebKit.

Hi I'm trying to inject JS into the DOM dynamically, but I'm having trouble getting a result from the injected JS which *would* give me a result when I loaded the standard way from a file.
The html code in the webview is like this at first:
-awakeFromNib: [[webView mainFrame] loadHTMLString:@"<html><head><title> </ title></head><body style='border: 0; margin: 0; padding: 0'>loaded from -awakeFromNib</body></html>" baseURL:nil];

then, after didFinishLoadForFrame: is called, I try to dynamically reset the DOM:

-(IBAction)setJSInWebView:(id)sender { NSString * scriptPreamble = @""; NSString * scriptString = @""; DOMDocument *doc = [[webView mainFrame] DOMDocument]; DOMNodeList *list = [doc getElementsByTagName:@"HEAD"]; assert([list length] > 0); DOMNode *body = [list item:0]; DOMElement *el = [doc createElement:@"SCRIPT"]; [el setAttribute:@"type" :@"text/javascript"]; [body appendChild:el]; scriptString = [NSString stringWithFormat:@"%@%@%@", scriptString, scriptPreamble, scriptPostamble]; [el appendChild:[doc createTextNode:scriptString]];

[[webView mainFrame] loadHTMLString:[(DOMHTMLElement *)[[[webView mainFrame] DOMDocument] documentElement] outerHTML] baseURL:nil]; }
but once didFinishLoadForFrame: is called the result is null:
- (void)webView:(WebView *)webView didFinishLoadForFrame:(WebFrame *)frame { NSLog(@"didFinishLoadForFrame"); WebScriptObject * wso = [webView windowScriptObject]; id result; NSArray * args = [NSArray arrayWithObjects:scriptObject, nil]; result = [wso callWebScriptMethod:@"cocoacalling" withArguments:args]; NSLog(@"%@ result", result); }

I know my technique is in error in some way. Is there a way to dynamically inject JS like I'm trying to?
