clearData method

Removes one or more data formats from the clipboard through the dataTransfer object. For the clipboardData object, this method clears all formats.

Syntax


 retVal = object.clearData(format);

Parameters

format [in, optional]

Type: BSTR

A BSTR that specifies one or more of the following data format values to clear from a dataTransfer object.

Text

Removes the text format.

URL

Removes the URL format.

File

Removes the file format.

HTML

Standards information

There are no standards that apply here.

Remarks

If no format parameter is passed, the data formats are cleared.

For drag-and-drop operations, the IHTMLDataTransfer::clearData method of the dataTransfer object is used generally in source events, such as HTMLFrameSiteEvents::ondragstart. When you override the default behavior of the target, use IHTMLDataTransfer::clearData in the HTMLFrameSiteEvents::ondrop event. It is particularly useful for selectively removing data formats when multiple formats are specified.
