Hi all,
I have a question, perhaps a bit newbie-ish, but I think it's important
nonetheless. What is the proper way to handle errors reported by
back-end processes via Ajax? For instance, let's take a very simple
Ajax.Request call like this :
new Ajax.Request('delete_item.php',
{
method: 'post',
parameters: {action: 'delete', id: myId},
onSuccess: function() {
alert('success');
},
onFailure: function() {
alert('failure');
}
});
Ok, simple enough. Obviously the HTTP error codes are handled here,
albeit a bit generically. What about a non-HTTP error? What if, for
instance, myId was invalid? What is the proper way to pass that
information back to the ajax application? Is it ok to use a custom 4xx
error? Or should I be using JSON or XML to handle this?
Thanks!
