Support for JavaScript and JScript Objects in Opera

OperaはECMAScript第二版と第三版を完全にサポートしており、DOMレベル2も完全にサポートする予定です(独立したDOMに関する文書も将来出す予定です)。

現在、試験的にOperaは一部の例外を除き、JScriptのサブセットはもちろんJavaScript 1.4もサポートしています。OperaはUser AgentをMicrosoft Internet Explorerと設定した場合のみJScriptのプロパティをサポートします。これはFile > Preferences > Connections > Browser identificationから"Identify as MSIE 5.0"とすることによって設定できます。
