I want to delete NCMB objects.

We are developing with Monaca and nifty cloud.
I'd like to delete the object stored on the datastore in destroy, but should I get the objectId and delete it?
sample.get("objectId"; but the objectId is returned undefined.
Also, if not, please let me know the specific method.

var Notice=NCMB.Object.extend("notice");
var noticeQuery=new NCMB.Query("notice");

var notice = new Notice();
var array = new Array();

noticeQuery.find({
            // Successful
    success:function(objects){
        for (vari=0;i<objects.length;i++){
            array[i] = objects[i].get("objectId");
            notice.set("objectId", array[0]);
            notice.destroy();
            notice.save();
        }
    },

    // In case of failure
    error: function(error) {
        // Error indication
        alert('Failed to get object, with error code:'+error.description);
   }
});
