The iPhone 3.0 software added copy/paste, and native application can programmatically copy content to the clipboard. Is it possible to do the same, i.e. copy text to the clipboard, from JavaScript code running inside Safari on the iPhone?
回答1:
On the desktop, copy/paste in websites typically seems to use an embedded Flash gizmo; obviously on the iPhone that's neither possible nor desirable. You might try one of the webView:shouldStartLoadWithRequest:navigationType: techniques discussed in Nick Dalton's presentation here to pull information out of your web view, then call an appropriate UIPasteboard method.
edit: My apologies—didn't read the post correctly. If it's in the main Safari app as opposed to one whose UIWebView you control, I don't think there is a way to force a copy. Glyphboard (site only works from within non-desktop Safari) is an example of a site that would probably be making use of this functionality if it existed.
