DataTransfer.setData()
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2015年7月.
DataTransfer.setData() メソッドは、ドラッグ操作の drag data に指定したデータと型を設定します。与えられた型のデータが存在しない場合、このデータはドラッグデータストアの末尾に加えられ、このような types リストの最後の項目は新しい型になります。与えられた型のデータが存在する場合、既存のデータが同じ位置で置き換えられます。同じ型のデータが置き換えられる時、types リストの並び順は変更されません。
データ型は、例えば text/plain や text/uri-list です。
構文
js
setData(format, data);
引数
format-
文字列で、ドラッグオブジェクトに追加するドラッグデータの型を表します。
data-
文字列で、ドラッグオブジェクトに追加するデータを表します。
返値
なし (undefined)。
例
この例は、DataTransfer オブジェクトの getData() メソッドおよび setData() メソッド、clearData() メソッドの使い方を紹介します。
