我正在尝试制作一个数组marklistdetails来发布多个学生的详细信息，我无法在控制器上访问相同的内容，这会在对象未初始化时给出错误
json代码
var MarksEntry = { Adm_Or_Name：''， 入场号：''， 名称： ''， 班级号： ''， ClassSectionId：''， RollNo：''， MarksEntered：''， 备注：''， Subjectid：''， 考试ID：''， ExamDate：''， 当下： ''， MarksEntryDetails：[]，
};
var MarksEntryDetails =
{
// StudentId: '',
MarksEntered: '',
// RemarksEntered: '',
// Total_Oral_Marks: '',
// TOTAL_PRACTICAL_MARKS: '',
//TOTAL_PROJECT_MARKS: '',
//TOTAL_MARKS: '',
// PRESENT: '',
// PASS_FAIL: '',
};
function SavingRecords(url) {
var result = 0;
var Index = 0;
//var marksEntrylist = [];
MarksEntry.ClassSectionId = $("table#IntialDetails tr").find("td").eq(6).html()
MarksEntry.ExaminationID = $("table#IntialDetails tr").find("td").eq(7).html()
MarksEntry.Subjectid = $("table#IntialDetails tr").find("td").eq(8).html()
$('table#student_marks tr').each(function () {
MarksEntry.MarksEntryDetails.add(new CreateMarksEntry(this));
console.log(MarksEntry.MarksEntryDetails);
$.getJSON(url,JSON.stringify(MarksEntry), function (data) {
Success = data;
});
// return Success
// alert(marksEntrylist);
//Index = $(this).index() + 1;
// MarksEntry.ExamDate = Formateddate;

if (result > 0) {

发布数据时，可以使用JSON.stringify将对象传递给控制器。
$.ajax(
{
url: 'controller/CreateRecords',
data: JSON.stringify({MarksEntry: MarksEntry}),
contentType: 'application/json',
dataType: 'json',
type: 'POST',
success: function (data) {
// success
},
error: function () {
// error
}
});

它说明了我们如何将复杂的javascript对象传递给MVC控制器。
谢谢！
