Hi MorningZ:
I think your first approach is better for me.
Finally I do:
beforedelete: function(NODE)// before delete - should return true |
false
{
$.ajax({
type: "POST",
url: "/goicms/admin/removenode",
async: false,
data: "node=" + NODE,
success: function(data)
{
if (data == 1)
isOK = true;
else
isOK = false;
});
return isOK;
}
Thank you very much for your help.
