Clipboard.readText() - Web APIs 编辑

The Clipboard interface's readText() method returns a Promise which resolves with a copy of the textual contents of the system clipboard.. The "clipboard-read" permission of the Permissions API must be granted before you can read data from the clipboard.

Syntax

var promise = navigator.clipboard.readText()

Parameters

None.

Return value

A Promise that resolves with a DOMString containing the textual contents of the clipboard. Returns an empty string if the clipboard is empty, does not contain text, or does not include a textual representation among the DataTransfer objects representing the clipboard's contents.

To read non-text contents from the clipboard, use the read() method instead. You can write text to the clipboard using writeText().

Example

This example retrieves the textual contents of the clipboard and inserts the returned text into an element's contents.

navigator.clipboard.readText().then(
  clipText => document.getElementById("outbox").innerText = clipText);
