Drupal7を使用しています。私のテーマはオメガです。そして、私のサイトにファイルフィールドがあります。すべてのPDFファイルとすべてが機能していることをアップロードしました。
しかし、FirefoxでPDFファイルをクリックすると、PDFファイルのダウンロードが開始されます。Chromeをクリックすると、同じページでPDFが開きます。
Firebugによってチェックされ、pdfファイルのhtmlコードはここにあります：
<span class="file"><img src="/modules/file/icons/application-pdf.png" title="application/pdf" alt="" class="file-icon"> <a title="myfile.pdf" type="application/pdf; length=1620377" href="http://mysite.net/sites/default/files/myfile.pdf">Click to Download</a></span>
PDFファイルをクリックして新しいタブを開きたいので、属性を作成します。Drupalファイルモジュールは（file.js）です：
/**
* @file
* Provides JavaScript additions to the managed file field type.
*
* This file provides progress bar support (if available), popup windows for
* file previews, and disabling of other file fields during Ajax uploads (which
* prevents separate file fields from accidentally uploading files).

page.tplファイルがないので、このjQueryまたは別の方法が必要です。これどうやってするの？
