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

冒泡	Yes
可取消	Yes
接口	`ClipboardEvent`
事件处理程序特性	`onpaste`

If the cursor is in an editable context (for example, in a <textarea> or an element with contenteditable 属性设置为 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 特性。

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.

HTML

<div class="source" contenteditable="true">Try copying text from this box...</div>
<div class="target" contenteditable="true">...and pasting it into this one</div>

CSS

div.source, div.target {
    border: 1px solid gray;
    margin: .5rem;
    padding: .5rem;
    height: 1rem;
    background-color: #e9eef1;
}

JS

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 false;
    selection.deleteFromDocument();
    selection.getRangeAt(0).insertNode(document.createTextNode(paste));
    event.preventDefault();
});
