You can use document.height or document.width from javascript


document.height


document.width


// in init
_WebView.delegate = YourClass; // probably self

- (void) webViewDidFinishLoad:(UIWebView *)webview

int w = [[_WebView stringByEvaluatingJavaScriptFromString:@"document.width"] floatValue];
_WebView.userInteractionEnabled = w > 200;

document.width returns always width of iphone screen (320), document.height works fine.

No, document.width return the width of your page. If your page use meta tags for iphone, size is 320px.

There's water in the way. – Roddy of the Frozen Peas Dec 12 '16 at 7:42 I presume the route is somehow Malaysia-East Timor-Darwin Australia and on. But even these fine fellas abikejourney.com have flown from Singapore to Australia. With the increasing difficulty in freighter tourism, this will be at least very challenging. – chx Dec 12 '16 at 10:01 add a comment  |  10 Is it possible to ride from Malaysia to Papua New Guinea by motorcycle.
