Question

If I have data in json like this :

{"items":[{"id":"2049","channel_code":"HBD","channel_name":"HBO HD"}]}

And if you search my data to the server could not find results like this :

{"items":[]}

Of output as above, how do I read that my data does not exist or is empty?

I have written some code that I got but have not found the results I want.

This code :

var data = { Name: "John Doe", Age: 25, Address: null, CityState: "Denver, CO" };
for (member in data) {
if (data[member] != null)
    //Do something
}

or

if (myObject == '') {
   alert('this object is empty');
}

Maybe someone can help me find a way out of this example.
Please help

To check whether your array is empty, just use the respective length property:

if ( data['items'].length < 1 ) {
   // it's empty
}
