getData Method | Internet Development Index |
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.
Examples

<HEAD> <SCRIPT> function InitiateDrag(){ event.dataTransfer.setData(oSource.innerText); } function FinishDrag(){ window.event.returnValue=false; oTarget.innerText = event.dataTransfer.getData("Text"); } function OverDrag(){ window.event.returnValue=false; } </SCRIPT> </HEAD> <BODY> <B ID="oSource" ondragstart="InitiateDrag()"> drag this text</B> <SPAN ID="oTarget" ondragover="OverDrag()" ondragenter="FinishDrag()""> drop text here</SPAN> </BODY>This feature requires Microsoft® Internet Explorer 5 or later.
