[19] 近年の多くの [[Webブラウザー]]には、[[Webページ]]の開発者向けのツールが標準で組み込まれています。
[18] [[HTML Standard]] は[DFN[[RUBYB[開発者コンソール]@en[development console]]]]や[DFN[[RUBYB[開発コンソール]@en[development console]]]]という呼称で[[エラーの報告]]などで言及していますが、
その詳細を規定しているわけではありません。
[36] [CITE[Service Workers]] は単に「console」と呼んでいます。
* 報告
[21] 次の場面で、[[開発者コンソール]]へ[[エラー]]などを報告することができると[[仕様書]]により明示されています。
[FIG(middle list)[
- [[例外の報告]]
- [[イベントハンドラーの現在値を取得]]
- [CODE(HTMLa)@en[[[pattern]]]] [[属性値]]の[[コンパイル]]失敗
- [[受動的]]な[[イベントリスナー]]からの [CODE(DOMm)@en[[[preventDefault]]]]
- [CODE(DOMm)@en[postMessage]] の誤った利用
- [[handle fetch]]
]FIG]
[23] 他に次の場面で報告する実装があります。
[FIG(middle list)[
- [[同期モード]]の [[XHR]]
- [[fetch]] 失敗、例えば:
-- [[混合内容]]制約違反
-- [[同一起源ポリシー]]違反
-- [[CORS]] エラー
-- [[HTTP]] エラー
-- [[TLS]] エラー
-- その他[[ネットワークエラー]]
- [[WebSocket]] のエラー
- [[構文解析誤り]]
]FIG]
[31] 次のものも報告できます。
[FIG(middle list)[
- [[URL構文解析器]]の[[構文違反]]
]FIG]
[34] [[制約群を対話的に検証]]した結果、「スクリプト誤りを報告」
する場合があります。 ([[誤りを報告]]にはリンクされておらず、
詳細な規定もないのですが、[[開発者コンソール]]への報告が意図されていると思われます。)
