|
|
* a paste bin element and move focus to that element.
|
|
* 2. Wait for the browser to fire a "paste" event and get the contents out of the paste bin.
|
|
* 3. Check if the paste was successful if true, process the HTML.
|
|
* (4). If the paste was unsuccessful use IE execCommand, Clipboard API, document.dataTransfer old WebKit API etc.
