InputEvent: dataTransfer property

The dataTransfer read-only property of the InputEvent interface returns a DataTransfer object containing information about richtext or plaintext data being added to or removed from editable content.

Value

A DataTransfer object or null. The spec has an overview of its value in various cases.

Examples

In the following simple example we've set up an event listener on the input event so that when any content is pasted into the contenteditable <p> element, its HTML source is retrieved via the InputEvent.dataTransfer.getData() method and reported in the paragraph below the input.

Try copying and pasting some of the content provided to see the effects.

html

<p><span style="font-weight: bold; color: blue">Whoa, bold blue text!</span></p>
<p>
  <span style="font-style: italic; color: red">Exciting: italic red text!</span>
</p>
<p>Boring normal text ;-(</p>

<hr />

<p contenteditable="true">
  Go on, try pasting some content into this editable paragraph and see what
  happens!
</p>

<p class="result"></p>

const editable = document.querySelector("p[contenteditable]");
const result = document.querySelector(".result");

editable.addEventListener("input", (e) => {
  result.textContent = e.dataTransfer.getData("text/html");
});
