如何解决（未捕获的TypeError：将循环结构转换为JSON）

Question

 var feeTransactionsArray=[];

                 $(".editor #newPayTable .mainTr").each(function(){ 

                     var feeTransactions={};
                     var studentDetails={};
                     var feeCategory={};


                     studentDetails['studentAdmissionId']=id;

                     feeCategory['feeCatId']=$(this).find('.feeCatId').val();

                     feeTransactions['studentDetails']=studentDetails;

                     feeTransactions['feeCategory']=feeCategory;

                     feeTransactions['paidOn']=paidDate;

                     feeTransactions['transReceiptNo']=receciptNumber;

                     feeTransactions['amountPaid']=$(this).find('.amount').val();

                     feeTransactions['paymentMode']=mode

                     feeTransactions['amountPaid']=refrenceNumber;

                     feeTransactions['isConcessionGiven']='no';

                     feeTransactionsArray.push(feeTransactionsArray);
                 });
                 var myJSON = JSON.stringify(feeTransactionsArray);

在JSON中不可能对循环结构进行字符串化。让我们来看一个例子：

var a = { a: undefined };
var b = { b: a };
a.a = b;

然后，我们就有了一个对象：

{ a: { b: { a: { b : { a ... infinite recursion

…这将导致您所描述的错误。
