@Andres: This sounds like a Firefox issue and not an iPhone Development issue.

Hi, I came across this blog article while searching for help with JavaScript. I’ve recently switched browsers from Opera to Mozilla Firefox 3.1. Just recently I seem to have a problem with loading JavaScript. Everytime I browse page that requires Javascript, the page does not load and I get a “runtime error javascript.JSException: Unknown name”. I cannot seem to find out how to fix it. Any aid is greatly appreciated! Thanks

@Walker: Unfortunately the JavaScript API for the YouTube player does not work in a UIWebView. We spent a week trying to figure out how to use JavaScript to play a video, to no avail.

@Nick:Hi, Nick! Do you know how to use javascript to control YouTube player? I want to play a video from YouTube in my iPhone app, but I don’t want the embed preview page. I wonder if I can control the player. Do you know how? Please help me, and thank you in advance!

Hi, this is my question. How can I change this to only show one image or id or tag? Any help would be great.

you can also call a JS file from a bundle (get around that readability snag and have as many fnctions as you need)….

NSString *filePath = [[NSBundle mainBundle] pathForResource:@”loco” ofType:@”js” inDirectory:@”"];

NSData *fileData = [NSData dataWithContentsOfFile:filePath];

NSString *jsString = [[NSMutableString alloc] initWithData:fileData encoding:NSUTF8StringEncoding];

[webby stringByEvaluatingJavaScriptFromString:jsString];
