ClipboardData object
Provides access to the clipboard.
Three methods
1. cleardata (sdataformat) deletes data in the specified format on the clipboard.
2. getdata (sdataformat) obtains data in the specified format from the clipboard.
3. setdata (sdataformat, sdata) assigns data in the specified format to the clipboard. True indicates that the operation is successful.

VaR text = "123 ";
If (! Window. clipboardData. setdata ('text', text) // assign data in text format
{
Alert ("copying failed! ");
}
TEXT = Window. clipboardData. getdata ('text'); // obtain text data
Alert (text );
Window. clipboardData. cleardata ('text'); // clear text data
TEXT = Window. clipboardData. getdata ('text ');
Alert (text );
