このリモートスクリプトによりIE6がハングするのはなぜですか？

StackOverflow https://stackoverflow.com/questions/185149

質問

下記のhtmlを見て、リモートスクリプト（ ' http://code.katzenbach.com/Default.aspx '）。スクリプトはJSONPを返し、ヘッダーにリストされている「callbackFunction」を実行します。正常に実行されると、1〜500の数字を示すポップアップアラートが表示されます。これはFF3およびIE7で正常に機能します。 Internet Explorer 6で失敗する理由がわかりません。プロセッサが固定され、すべてがハングします。

自分で実行し、同じ問題が発生した場合はお知らせください。私は一日中この問題を見つめてきた。ご協力ありがとうございます。

役に立ちましたか？

解決

スクリプトに直接アクセスする場合（ http：// code .katzenbach.com / Default.aspx？callback = callbackFunction＆amp; test = true＆amp; c = 500 ）、ファイル（不明なMIMEタイプ）が処理されていないことがわかります。これは、サーバーのセットアップに問題がある可能性があります。 .aspxを処理し、代わりにファイルをストリーム配信しようとする方法を知らないようです。

他のヒント

FiddlerとIE6を調べたところ、通常とは異なるものを見ることができませんでした（ブラウザがフリーズするという事実を除く）。

http://code.katzenbach.com/Default.aspx?callback=callbackFunction&test=true&c=500 へのリクエストは行われ、2909バイトを返します。

次の3つを提案します。

  1. Content-Typeからセミコロンの1つを削除します： application / json ;; charset = utf-8 またはセミコロンと charset = utf-8 の両方を完全に削除する（テストのみ）
  2. callbackFunction
    3. の最後の）の送信が完了したら、改行文字を送信します
  3. これを Content-Type：text / javascript に変更します。これは、実際にブラウザにJavascriptを返しているためです。他のコンテンツタイプはIE6を混乱させる可能性があります（ほとんどありませんが）。 >

私は1を考えています。 IE6には、2つのセミコロンが検出されると無限ループに入る解析バグがある可能性があります。そうでなければ、あなたがやっていることが機能しないはずの理由がまったくないからです。

テストとして別のMIMEタイプを試すことも価値があります。

外部スクリプトの戻り値は次のとおりです：

なぜこれを警告するのですか？
