Ändern REGEX JavaScript-Code, um PDF-Dateien zu akzeptieren

Question

Ich habe reine PHP-Upload verwendet, um eine Upload-Seite zu erstellen. Es können jedoch nur die folgenden Bild-Erweiterungen hochgeladen werden. gif | jpg | png | bmp | jpeg

sah ich in der Bibliothek Script und fand diesen Code in der JavaScript-Datei

re=new RegExp(".(gif|jpg|png|bmp|jpeg)$","i");

Ich bin sicher, dies ist der Code muss ich ändern pdf zu ermöglichen Dateien, die hochgeladen werden sollen. Für JavaScript-Experten ist der gesamte Code wie folgt. Bitte helfen

geschätzt werden pdf Dateien Damit Sie nur pdf in regex Änderung hinzufügen müssen.

Regex:re=new RegExp("\.(gif|jpg|png|bmp|jpeg|pdf)$","i");
