@interface UIWebView (JavaScriptAlert) 

- (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame;

@end

@implementation UIWebView (JavaScriptAlert)

- (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame {
    UIAlertView* dialogue = [[UIAlertView alloc] initWithTitle:nil message:message delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil];
    [dialogue show];
    [dialogue autorelease];
}

@end
