Element: paste event

The paste event is fired when the user has initiated a "paste" action through the browser's user interface.

If the cursor is in an editable context (for example, in a <textarea> or an element with contenteditable attribute set to true) then the default action is to insert the contents of the clipboard into the document at the cursor position.

A handler for this event can access the clipboard contents by calling getData() on the event's clipboardData property.

To override the default behavior (for example to insert some different data or a transformation of the clipboard contents) an event handler must cancel the default action using event.preventDefault(), and then insert its desired data manually.

It's possible to construct and dispatch a synthetic paste event, but this will not affect the document's contents.


Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener('paste', (event) => { });

onpaste = (event) => { };

Live example


<div class="source" contenteditable="true">Copy text from this box.</div>
<div class="target" contenteditable="true">And paste it into this one.</div>


const target = document.querySelector('div.target');

target.addEventListener('paste', (event) => {

    let paste = (event.clipboardData || window.clipboardData).getData('text');
    paste = paste.toUpperCase();
    const selection = window.getSelection();
    if (!selection.rangeCount) return;
