Javascript Check Json Output Is Empty

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

Solution 1:

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

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

Solution 2:

You want to check if data.items.length > 0. Assuming

var data = {"items":[]};

Solution 3:

for (member in data) {
if (data[member] != null)
    //Do something
}

code inside for will not run because length of data is 0

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

myObject wont be null because the object actually is there and its an empty array

you should check for myObject.length because its an empty array
