How to tell if JSON object is empty in jQuery

rated 0 times [ 136] [ 6] / answers: 1 / hits: 31712 / 11 Years ago, fri, november 1, 2013, 12:00:00

I have the following JSON:

{

    meta: {

        limit: 20,

        next: null,

        offset: 0,

        previous: null,

        total_count: 0

    },

    objects: []

}

I'm interested in objects: I want to know if objects is empty and show an alert:

something like this:

success: function (data) {

    $.each(data.objects, function () {

        if data.objects == None alert(0)

        else :alert(1)

    });

Use Array's length property:

// note: you don't even need '== 0'



if (data.objects.length == 0) {

  alert(Empty);

}

else {

  alert(Not empty);

}
