## Examples

This example shows when and where each event fires during a drag-and-drop operation by listing each event and the name of the object firing it in a list box.

<HEAD>
<SCRIPT>
// 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;
  var 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"
    ondragstart="ShowResults()"
    ondrag="ShowResults()"
    ondragend="ShowResults()"
>
<P>Target events are bound to this text box.</P>
<INPUT ID=txtDragDestination VALUE="Drag Destination"
    ondragenter="ShowResults()"
    ondragover="ShowResults()"
    ondragleave="ShowResults()"
    ondrop="ShowResults()"
>
<SELECT ID=oResults SIZE=30>

Notes

Remarks

The dragover event fires on the target object after the dragenter event has fired. When scripting custom functionality, use the returnValue property to disable the default action. Calls the associated event handler. To invoke this event, do one of the following:

Drag the selection over a valid drop target within the client.
Drag the selection to a valid drop target within another window.
