Hi, Mike.

That's exactly what it does;

The exact WebView UI delegate is:

- (void)webView:(WebView *)webView addMessageToConsole:(NSDictionary *)dictionary;

So anytime there's a _javascript_ exception, your addMessageToConsole (in your WebView UI delegate) is invoked, complete with dictionary.

Cheers,

Kevin

That would be useful, but how can I make WebKit send me the NSDictionary containing the error? In your example, you've created the line number, message and source via an NSDictionary. It would be very useful if WebKit did that automatically.

Hi Mihkel.

Poking around in WebKit and WebCore, I found that the WebView UI delegate can implement the following undocumented method:

webView:addMessageToConsole:

The delegate method gets called like so:

NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:
(NSString *)message, @"message",
[NSNumber numberWithInt: lineNumber], @"lineNumber",
(NSString *)sourceURL, @"sourceURL",
NULL];
[_bridge addMessageToConsole:dictionary];

Since this is undocumented behavior, it's likely to change in the future. But it should be fine to use for debugging purposes.
