var ajax = KAIDEN.Ajax(); //call ajax library
var criteria = {};        //value to be sent to the server

//ajax execution (POST communication)
ajax.postAuto("/*URL*/"
   , criteria
   , function(returnData) {
       //process at normal time
     }
   , function(returnData) {
       //process at error time
     }
   , function(returnData) {
       //process at warning time
     }
);

When ajax communication ends,

1. Message is automatically displayed accordint to the LogicResultDto.status contents. *only when message is set

• In case of “success”, it displays success message by using imuiShowSuccessMessage()
• In case of “fail”, it displays error message by using imuiShowErrorMessage()
• In case of “warn”, it displays warning message by using imuiShowWarningMessage()

2. Each method is called according to the LogicResultDto.status contents.

   At this point, the value which was set in  LogicResultDto.data is passed to the argument.

Following methods are used when you do synchronous communication.

• postSyncAuto();
• getSyncAuto();

Following methods are effective when you control message display or other behaviours in detail.

• post();
• get();

Both methods return $.ajax(), so the programmer can control in detailed.
