- Thread-topic: Call getElementById in Cocoa
Does this code convey what you are saying/how to do this?
IBOutlet id webView;
NSString *urlOfObject = [NSString stringWithFormat:
@"http://www.somesite.com/hiddenFieldPage.php";];
[[webView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL
URLWithString:urlOfObject]]];
DomDocument *domObject = [webView mainFrameDocument];
NSString *hiddenField = [domObject getElementById:@"hiddenField"];
Also, how would the link that you gave come into play in this case?
Sincerely,
Pierce F
