Student类有集合属性Courses，如何把Student连同集合属性Courses传递给控制器方法？
public class Student
{
public string StudentName { get; set; }
public IList<Course> Courses { get; set; }
}
public class Course
{
public string CourseName { get; set; }
}
□ 思路
在前端拼装成与Student吻合、对应的对象，再使用JSON.stringify()或$.toJSON()方法转换成json格式传递给控制器方法，使用$.toJSON()方法需要引用一个jQuery的扩展js文件。
□ Home/Index.cshtml
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<a id="btn" href="javascript:void(0)">走你</a>
@section scripts
{
<script src="~/Scripts/json.js"></script>
<script type="text/javascript">
$(function () {
$('#btn').click(function() {
var arr = [];
var obj1 = new Object();
obj1.CourseName = "语文";
arr.push(obj1);
var obj2 = new Object();
obj2.CourseName = "数学";
arr.push(obj2);
var student = {
StudentName: '小明',
Courses: arr
};
//var json = JSON.stringify(student);
var json = $.toJSON(student);
$.ajax({
url: '@Url.Action("GetStuent","Home")',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: json,
dataType: 'json',
success: function (data) {
alert(data.StudentName);
for (i = 0; i < data.Courses.length; i++) {
alert(data.Courses[i].CourseName);
}
}
});
});
});
</script>

□ 把对象转换成json格式的jQuery扩展

i, // The loop counter.
k, // The member key.
l, // Length.
