Try{

$.ajax ({

Async:false,

Url:sivrs_hascard_url,

DataType:' Jsonp ',

JSONP: "Callback",

Success:function(result) {

var results=eval (Result)

var result=results.result;

if (Result = = 1) {

Alert ("the shareholder card number already exists");

Returnfalse;

}

},

Error:function(XHR, Textstatus, Errorthrown) {

//alert (' ERROR: ' + errorthrown);//not Login

},

timeout:5000

});

} catch(ex) {

Alert ("Erorr");

}

@RequestMapping(value="/hascard.do")

Public void Hascard (httpservletrequest request,
