Widget degli Ultimi Commenti con avatar del commentatore.

Come installare e personalizzare su piattaforma Blogger il widget dei commenti recenti con l'avatar del commentatore

Mostrare gli Ultimi Commenti nel layout del nostro sito su Blogger può essere un buon modo per invogliare i lettori a leggerli e quindi a aumentare la permanenza media e il numero di pagine viste. Ricordo di aver presentato diverse versioni dei Commenti Recenti. C'è quella più utilizzata che è anche la più semplice, che non ha particolari controindicazioni, e l'altra che mostra gli Ultimi Commenti in un elenco verticale e quella dei commenti visualizzati accanto all'avatar del commentatore.

Il gadget con l'immagine del suo autore ha la particolarità di appoggiarsi a javascript caricato su Google Sites e di mostrare quadrate le miniature con Internet Explorer che invece con gli altri browser sono circolari. I siti con dominio personalizzato dovranno quindi caricare il javascript su un proprio hosting tipo DropBox per poter installare il widget. Il blog vietnamita Duy Pham ha realizzato un gadget che mostra i commenti recenti con avatar senza bisogno di un javascript aggiuntivo. Permangono i problemi di una corretta visualizzazione con Internet Explorer.

Vado a presentarvi questo nuovo gadget che ho modificato traducendo le espressioni in italiano e inserendo un CSS che impedisse di visualizzare gli antiestetici puntini degli elenchi presenti in alcuni modelli. Quando si passa con il mouse sopra al titolo di un post che è stato commentato si visualizzerà un tooltip con il contenuto del commento mentre se si passa con il mouse sul nome del commentatore il tooltip ci avvertirà che cliccandoci sopra potremo aprire la pagina del suo Profilo

Per la installazione del widget non occorre modificare il modello né inserire l'URL del nostro sito. Basta andare su Layout > Aggiungi un gadget > HTML/Javascript e incollare questo codice in Sezioni del sito
