## Examples
This example uses event bubbling to handle the ondragstart event at the body level.
<body ondragstart="console.log(event.srcElement.tagName)">
<input type="text" value="Select and drag this text">
Select and drag this text
<textarea>Select and drag this text</textarea>
</body>
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>
function ShowResults()
{
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>
<OPTION>List of Events Fired
</SELECT>
</BODY>
The ondragstart event is the first to fire when the user starts to drag the mouse. It is essential to every drag operation, yet is just one of several source events in the data transfer object model. Source events use the setData method of the dataTransfer object to provide information about data being transferred. Source events include dragstart, drag, and dragend. When dragging anything other than an img object, some text to be dragged must be selected. Calls the associated event handler. To invoke this event, do one of the following:
