 8. Subscribe to the status (online/offline) changes of the distributed data object. A callback will be invoked to report the status change when the target distributed data object goes online or offline.
    The sample code is as follows:
    ```js
-    statusCallback : function (sessionId, networkid, status) {
+    statusCallback : function (sessionId, networkId, status) {
       this.response += "status changed " + sessionId + " " + status + " " + networkId;
     }
    
-    local_object.on("status", this.changeCallback);
+    local_object.on("status", this.statusCallback);
    ```
 9. Unsubscribe from the status changes of the distributed data object. You can specify the callback to unsubscribe from. If you do not specify the callback, all status change callbacks will be unsubscribe from.

 8. 监听分布式对象的上下线。可以监听对端分布式数据对象的上下线。
    以下为访问对象的代码示例：
    ```js
-    function statusCallback(sessionId, networkid, status) {
+    function statusCallback(sessionId, networkId, status) {
       this.response += "status changed " + sessionId + " " + status + " " + networkId;

 9. 删除监听分布式对象的上下线。可以指定删除监听的上下线回调；也可以不指定，这将会删除该分布式数据对象的所有上下线回调。
