Si je comprend bien, la ligne suivante est dépendante de la structure HTML de la page Web du résolveur de lien ?

var openurl = jQuery("#RefinerLink0 a").attr('href’); 

Mais à quoi correspond ce lien concrètement ? c'est un lien vers une des cibles que le résolveur de lien à réussi à trouver, donc potentiellement cliquable par l'utilisateur ? ou alors autre chose, mais quoi ?

C’est la requête open URL qui a été passée au résolveur
