Question

I have a function like this:

$.getJSON('<?php echo site_url('get_leads/main_contact'); ?>', 
        function(data) {
              ...
           });

It works fine. But sometimes there is no data coming back from the server? How do I detect if the JSON object is empty? I tried “if(data == ”)” and it didn’t work.

Answer 1

Use jQuery.isEmptyObject

if (!jQuery.isEmptyObject(data)) {
    // We have data
}

This will at least capture an empty array, an empty object, null and undefined.
