jQuery: how to handle empty return from getJSON
- by Gee
Alright so I have a php script which gets results from a DB, and to get those results I'm using a jQuery script to pull the results via getJSON. It works perfectly but now I want to do something if the php script returns no results (empty).
I tried:
$.getJSON('path/to/script'), {parameter:parameter}, function(data){
if (data) {
alert('Result');
} else {
alert('Empty);
}
});
But it's no good. I've tried different things like if (data.length) but still nothing. I've noticed that if there is no returned data the callback will never fire at all. So if that's the case, how do I handle a empty return?
