On Mac OS you can use the DOM APIs. On iOS I think you have to run JavaScript on the page — I don’t remember the exact method name, but there’s a method you pass a string containing JavaScript and it evaluates it. —Jens___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: selected image in webview
Thanks, It is for Mac OS (coredata app), but all the documentation seems to refer to Javascript? I've got a webView *manWeb, and I use this to set the initial page to display; NSString *manWebString = [[Manufacturers selection] valueForKey:@manufacturerNewWeb]; [[manWeb mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:manWebString]]]; Then I navigate through the pages by clicking on the links on the pages etc. This isn't meant to be a full browser experience, I just want to access my suppliers sites for quick reference. I'm still struggling to find a way to select an image within the page. I'd like to simply click on an image within the webview, then a button in my UI to process it. I'll basically be downloading it, and saving the details to my app. Then I have more relationships to set etc, but I just can't work out how to know what image has been selected? I'd appreciate any help, Many Thanks Amy On 5 Jul 2011, at 5:07PM, Jens Alfke wrote: On Jul 4, 2011, at 10:55 PM, Amy Heavey wrote: Is there a way to get the selected item in a webview?

It’s a cross-language API, but there are Objective-C bindings in WebKit. Read the section Using the Document Object Model from Objective-C” in the WebKit Programming Guide. The method to start with is -[WebFrame DOMDocument] which will return the document object. From there you can walk the node tree, get the selection, etc. I'm still struggling to find a way to select an image within the page. I'd like to simply click on an image within the webview, then a button in my UI to process it. I’m not sure what the best way of doing this would be. In either case you have to intercept and modify the normal event handling in the view. You might have better luck asking on one of the webkit mailing lists on this server. —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
