- hrefMsg
- the message to be dispatched with the result of the request. The message data contains three keys. "url" returns the anchor's href attribute. "title" returns the anchor's text. "src" returns the image's src attribute.
Requests the anchor or image element URL at the last tapped point. If hrefMsg is null, this method returns immediately and does not dispatch hrefMsg to its target. If the tapped point hits an image, an anchor, or an image in an anchor, the message associates strings in named keys in its data. The value paired with the key may be an empty string.
