Methods Method Description
clearData Removes one or more data formats from the clipboard through the dataTransfer object or the clipboardData object.
getData Gets the data in the specified format from the clipboard through the dataTransfer object or the clipboardData object.
setData Assigns data in a specified format to the dataTransfer object or the clipboardData object.


Remarks

The clipboardData object is reserved for editing actions performed through the Edit menu, shortcut menus, and shortcut keys. It transfers information using the system clipboard, and retains it until data from the next editing operation replaces it. This form of data transfer is particularly suited to multiple pastes of the same data.

This object is available in script as of Microsoft Internet Explorer 5.

Example

This example uses the setData and getData methods with the clipboardData object to perform a cut-and-paste operation through the shortcut menu.
