DragEvent: dataTransfer property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2020.
The DragEvent.dataTransfer read-only property holds the drag
operation's data (as a DataTransfer object).
Value
A DataTransfer object which contains the drag event's data.
The property can be null when the event is created using the constructor. It is never null when dispatched by the browser.
Examples
This example illustrates accessing the drag and drop data within the
dragend event handler.
js
function processData(d) {
// Process the data …
}
dragTarget.addEventListener("dragend", (ev) => {
// Call the drag and drop data processor
if (ev.dataTransfer !== null) processData(ev.dataTransfer);
});
