ok, thx, my mistake was the url wasn't good:
i do this from the backoffice :
$.ajax({ url:window.location.host +'index.php?option=com_cck&view=list&search=articles&task=search&Itemid=110' })
.done(function( html ) {
$( "#rendu" ).html( html );
});
but he understood this :
www.monsite/administrator/../index.php?option=com_cck&view=list&search=articles&task=search&Itemid=110
and the pagination was not loaded... but if i specifie the protocol, it's working :)
so i do
$.ajax({
url: window.location.protocol+'//'+window.location.host +'/'+'index.php?option=com_cck&view=list&search=articles&task=search&Itemid=110' })
Voila, thx :)
