如何在MobileSafari中接收复制的图像？

Question

I'm building an iOS website, and I'm trying to get the recently copied image using JavaScript.

When you hold your finger on a photo in a website a menu will pop-out with the option to Save the image or Copy . When you press copy and paste it later in a text-field, you can get the URL with:

pasteEvent.clipboardData.getData('text/uri-list');

When you copy an image in the camera roll, facebook application, or by selecting and you go to the same text-field (or textarea) the paste option is not available, however when going to the Mail.application the Paste option is available and pasts the image. So does anyone have a clue how to get the URL or binary data for a copied photo on an iPad?

Answer 1

This won't be possible for a website to do, as the javascript won't have direct access to any native elements.

if however, you are hosting a webview in a native application, a-la phonegap ... then you may be able to do something here by handling the paste in native code, and then making it available to the webview.
