I've thought about your post some more and I think this might actually
be ok. Considering that right now the only callback that is fired is
the success callback we can safely assume that people who are using
this method don't actually care about the error state - thus if we
pass in the normal error callback the page will still break (albeit in
a different manner).
Thus if you wanted to make proper use of the $.get or $.post with the
dual-callback functionality you would have to do:
$.get("someurl", function(data){
if ( typeof data === "string" ) {
// got results
} else {
// got error
}
});
Another option could be a modified error callback and actually have it
work like this:
$.get("someurl", function(data, errorMessage){
if ( data ) {
// got results
} else {
// got error
alert( errorMessage );
}
});
Thoughts on this?
