getData Method

Retrieves the data in the specified format from the clipboard through the dataTransfer or clipboardData objects.

Syntax

sRetrieveData = object.getData(sDataFormat)

Parameters

sDataFormat Required. String that 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.

Example

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.

Sample Code
This example uses the getData method to drag text and drop it in a new location.
<HEAD>
<SCRIPT>

  oTarget.innerText = event.dataTransfer.getData("Text");
}
function OverDrag(){
  window.event.returnValue=false;
}
</SCRIPT>
</HEAD>
<BODY>

<B ID="oSource"
