getData Method

Retrieves the data in the specified format from the clipboard through the datatransfer or clipboarddata objects.

dhtml语法

sretrievedata = object.getdata(sdataformat)

parameters

sDataFormat Required. Stringthat specifies one of the following data format values:
Text Retrieves data formatted as text.
URL Retrieves data formatted as a URL.

Return Value

String. Returns the data in the format retrieved from clipboard through the dataTransfer or clipboardData object. Depending on the information contained in setdata, this variable can retrieve a path to an image, text, or an anchor url.

remarks

the getdata method enforces cross-frame security and allows data transfers within the same domain only. to the user this means that dragging a selection between different security protocols, such as http and https, will fail. in addition, dragging a selection between two instances of the browser with different security levels, where the first instance is set to medium and the second is set to high, will fail. finally, dragging a selection into the browser from another drag-enabled application, such as microsoft® word, also will fail.
to use the getdata method to retrieve data from the clipboard within the oncopy or oncut event, specify window.event.returnvalue=false within the event handler script.

Examples

The following examples use the setData and getData methods of the dataTransfer object to drop text in a new location and create a desktop shortcut.
