Question

I’m doing a rowcount with JSON and get an output like this in my php file json_data2.php:

{"limit": [{"rows":"127"}]}

Now I’m calling this file using a Javascript/Jquery function and try to get the rows back (127). I pretend to do it like this:

function limit(keyword){
        $.getJSON("json_data2.php?l="+keyword,function(data)
        {
            $.each(data.limit,function(data){
                var rows = data.rows;
                return rows;
            });
        });
    }

But every time I call the function in the Script I get “undefined”. Any pointers?

You need to fix your each statement. Added this to refer to data in question.

http://jsfiddle.net/twGQh/

limit(keyword, function(rows) {
    // your rows have loaded
});

  function limit(keyword, cb){
            $.getJSON("json_data2.php?l="+keyword,function(data)
            {

                $.each(data.limit,function(){
                    var rows = this.rows;
                    console.log(rows);
                    cb(rows);
                });
            });
        }
