自分のサイトへのバック リンクをメールで送信する関数を作成しました。codeigniter フレームワークを使用しています。
ユーザーがメールでその特定のリンク (戻るリンク) をクリックすると、ユーザーは iframe を持つ私のページにリダイレクトされます。
その iframe を使用して、ページを更新せずに、ファイル入力を含むフォームを送信しました。
ユーザーが IE9 ブラウザーで gmail を使用してそのリンクを通過すると、form.submit()機能が失敗し、他のブラウザーでは正しく機能し、他の電子メール (gmail を除く) も機能します。
解決策を見つけるのを手伝ってください
ありがとうございました。

実際、私は ajaxupload jquery ライブラリを使用していますが、form.submit();上記のシナリオの行で 失敗します
