You can handle the ondragenter event on the source or on the target object. Of the target events, it is the first to fire during a drag operation. Target events use the getData method to stipulate which data and data formats to retrieve. The list of drag-and-drop target events includes:

onbeforepaste

onpaste

ondragenter

ondragover

ondragleave

ondrop

When scripting custom functionality, use the returnValue property to disable the default action.

Sample Code

<HEAD>
<SCRIPT>
var oNewOption;            

// Code for dynamically adding options to a select.

function ShowResults()
{                // Information about the events 
                 // and what object fired them.
  arg = event.type + "  fired by  " + event.srcElement.id;  
  oNewOption = new Option(); 
  oNewOption.text = arg;
  oResults.add(oNewOption,0);
}
</SCRIPT>
</HEAD>
<BODY>
<P>Source events are wired up to this text box.</P>
<INPUT ID=txtDragOrigin VALUE="Text to Drag"
