调用ajax的事件顺序如下：

1.beforeRequest

2.loadBeforeSend

3.serializeGridData

4.loadError (if a error from the request occur - the event from steps 5 till 7 do not execute. If there is no error the event 4. does not execute and we continue to with the step 5.)

5.beforeProcessing

6.gridComplete

7.loadComplete
