Clipboard.read()

The read() method of the Clipboard interface requests a copy of the clipboard's contents, delivering the data to the returned Promise when the promise is resolved. Unlike readText(), the read() method can return arbitrary data, such as images.

To read from the clipboard, you must first have the "clipboard-read" permission.

Syntax

var promise = navigator.clipboard.read();

Parameters

None.

Return value

A Promise that resolves with a DataTransfer object containing the clipboard's contents. The promise is rejected if permission to access the clipboard is not granted.

Example

After using navigator.permissions.query() to find out if we have (or if the user will be prompted to allow) "clipboard-read" access, this example fetches the data currently on the clipboard. If it's not plain text, an error message is presented. Otherwise, an element referred to using the variable textElem has its contents replaced with the clipboard's contents.

// First, ask the Permissions API if we have some kind of access to
// the "clipboard-read" feature.

navigator.permissions.query({name: "clipboard-read"}).then(result => {
  // If permission to read the clipboard is granted or if the user will
  // be prompted to allow it, we proceed.

  if (result.state == "granted" || result.state == "prompt") {
    navigator.clipboard.read().then(data => {
      for (let i=0; i<data.items.length; i++) {
        if (data.items[i].type != "text/plain") {
          alert("Clipboard contains non-text data. Unable to access it.");
        } else {
          textElem.innerText = data.items[i].getAs("text/plain");
        }
      }
    });
  }
});
