剪贴板事件：clipboardData 属性

The clipboardData 属性 of the ClipboardEvent interface holds a DataTransfer object, which can be used to

• specify what data should be put into the clipboard from the cut and copy event handlers, typically with a setData(format, data) call;
• obtain the data to be pasted from the paste event handler, typically with a getData(format) call.

See the cut, copy, and paste events documentation for more information.
