Interaction with web javascript cocoa
Hey, I have built a Javascript WYSIWYG editor. I want to build a WebKit based cocoa app with buttons that can call a function from the editor loaded in webkit. For example I want to have a button within the Cocoa interface that calls the Javascript function 'makeBold()' to make the selected text within the editor bold. If this is possible I then want to save the editor generated html to string so that I can store it within Core Data. I checked out the Apple Webkit programming guide but it doesn't provide much. Any help would be greatly appreciated.

Re: Interaction with web javascript cocoa
what i did is created the outlet to my webview, made the webview load
an html file that contains all my JS functions and then call it like so.
NSString *command = [[NSString alloc]
initWithFormat:@addMarkerAtPoint(%f, %f, 13, \%...@\);, [location
latitude], [location longitude], [location name]];
[mapOutlet sendMapCommand:command];
Now that sendMapCommand is a method I put in my mapController, here it
is
-(void)sendMapCommand:(NSString *)cmd
{
id map = [mapView windowScriptObject];
[map evaluateWebScript:cmd];
}
The ONLY downfall to this is that you can only make 1 function call
per command sent. I tried to do seperate calls and it would not
work. Combining the calls into functions and making 1 function call
has worked for me.
Thanks,
Joseph Crawford
