モジュール

モジュールスクリプト (JavaScript)

[53] JavaScriptモジュールスクリプトは、 スクリプトコンポーネントの単位の一つです。

仕様書

呼称

[32] JavaScriptモジュールHTMLモジュールスクリプトと呼んでいます。

[40] HTML は明確化のために仕様書の用語としてそう呼んでいるだけで、 API では module という語で表しています。

文脈

[41] script 要素により指定できます。

[45]

<script type=module src=path/to/module.js></script>

[42] ワーカーの作成時にも指定できます。

[46]

var worker = new Worker ("path/to/module.js", {type: "module"});

[44] 要素ワーカーからの指定では、ワーカースクリプトURL を使って指定します。従来の古典スクリプトと区別するため、 typemodule と明記する必要があります。

[43] JavaScript 内からも指定できます。モジュール指定子を使います。

状態

[20] モジュールスクリプトの持つ状態については、 スクリプトを参照。

[22] モジュールスクリプトモジュール記録 (module record) は、 構文解析され、評価できる状態のモジュールを表す Source Text Module Record (またはエラー時の null) >>21 です。

[30] WorkerGlobalScopeの値 module >>29WorkerType の値 module >>31 は、モジュールスクリプトを表します。

作成

[26] モジュールスクリプトの作成を参照。

実行

[27] モジュールスクリプトの実行を参照。

古典スクリプトとの違い

[33] スクリプトを参照。
