What is the process for downloading an image in MobileSafari?

I'm currently working on an iOS website and I am facing a challenge in retrieving recently copied images using JavaScript.

When you press and hold your finger on an image within a website, a menu appears with options to either Save the image or Copy. By pasting the copied image into a text field later on, you can obtain the URL using:

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

Interestingly, when copying an image from the camera roll, Facebook app, or through selection and then attempting to paste it into the same text field or textarea, the option is not available. However, when trying to paste in the Mail application, the Paste option is available and successfully pastes the image. Does anyone have any insight on how to retrieve the URL or binary data for a copied photo on an iPad?

For more information, refer to the Apple Documentation at the following link:

http://developer.apple.com/library/safari/#documentation/appleapplications/Conceptual/SafariJSProgTopics/Tasks/CopyAndPaste.html

Answer №1

It is not feasible for a website to accomplish this task, as JavaScript does not have direct access to native elements.

However, if you are using a webview within a native application, such as PhoneGap ... then you might have the capability to achieve this by managing the paste function in native code and then making it accessible to the webview.
