hi Marco,
are you waiting for WebView to report load finished before calling
javascript?
e.g. see example snippet (loads Google api and calls it):
#import <UIKit/UIKit.h>
@class UIWebView;
@interface WebViewController : UIViewController<UIWebViewDelegate> {}
@property (nonatomic, readonly) UIWebView *webView;
@end
#import "WebViewController.h"
@implementation WebViewController
@dynamic webView;
-(UIWebView *)webView
{
return (UIWebView *)self.view;
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSMutableString *htmlCode = [NSMutableString
stringWithString:@"<html><head>"];
[htmlCode appendString:@"<script type=\"text/javascript\" src=\"http://www.google.com/jsapi
\"></script>"];
[htmlCode appendString:@"<script type=\"text/javascript\">"];
[htmlCode appendString:@"google.load(\"language\", \"1\");"];
[htmlCode appendString:@"</script></head><body></body></html>"];
[self.webView loadHTMLString:htmlCode baseURL:nil];
}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
NSString *scriptCode = @"google.language.isTranslatable(\"en\")";
NSString *translatable = [webView
stringByEvaluatingJavaScriptFromString:scriptCode];
NSLog(@"isTranslatable: %@", (translatable) ? translatable :
@"error");
}
@end
regards,
Peter Blazejewicz

Hi,
i'm trying to execute a javascript function on the iPhone and get
the return value.
The function is simple:
return "hello";
I'm using a UIWebView and the -
stringByEvaluatingJavaScriptFromString: method but, while it works
on os x, it doesn't on the iPhone.
