Extjs使用Ext.ajax时报错：too much recursion

首先看代码：  
var record = viewModel.get(‘current.record’);  
Ext.Ajax.request(\{  
url: ‘ims/ckcp/audit/approve’,  
method: ‘POST’,  
headers: \{ ‘Content-Type’: ‘application/json’ \},  
params :Ext.JSON.encode(record),  
callback: function (options, success, response) \{  
if (success) \{  
var responseJson = Ext.JSON.decode(response.responseText);  
var returnRecord = responseJson.data;  
var success = responseJson.success;  
if (success)\{  
// viewModel.set(‘data.record’,returnRecord);  
Ext.Msg.alert(‘提示’,’账户审核通过成功’);  
\}  
else\{  
Ext.Msg.show(\{  
title:’失败’,  
message: responseJson.msg,  
buttons: Ext.Msg.YES,  
icon: Ext.Msg.ERROR,  
fn: function(btn) \{  
if (btn === ‘yes’) \{  
window.close();  
\}  
\}  
\});  
\}  
\} else \{  
Ext.Msg.confirm(‘失败’,  
‘请求超时或网络故障,错误编号：\[’ + response.status + ‘\]是否要重新获取账户信息？’, function (btn) \{  
if (btn == ‘yes’) \{  
Ext.Ajax.request(options);  
\}  
\});  
\}  
\}  
\}); //ajax

我的record是grid中选中的一列，其实就是一个Ext.data.Model的对象，如果在ajax中直接提交此对象就会报以下错误： too much recursion

所以我们不能直接提交整个对象，而是将对象中的属性及值封装一下作为参数提交，请看代码：

var record = viewModel.get('record');
                            var param = {
                                data:[{
                                    id:record.get('id'),
                                    accountNumber: record.get('accountNumber'),
                                    cardNumber: record.get('cardNumber'),
                                    subAccountNumber:record.get('subAccountNumber'),
                                    balance: record.get('balance'),
                                    hxInterest:record.get('hxInterest')
                                }]

然后在上面的ajax中的params中提交param
