javascript - ajax发送二维数组到操作方法错误 - asp.net mvc

Question

我想将 2d 数组从 javascript 文件发送到操作方法。我的 JavaScript 函数

function _tbdata() {

var dataarr = [];

for(var i = 0; i<svarr.length; i++)
{
    var trangthai = $("input[name='" + svarr[i] + "']:checked").val();
    var lydo = $("#" + svarr[i]).val();
    dataarr[i] = new Array(2);
    dataarr[i][0] = trangthai;
    dataarr[i][1] = lydo;
}
$.ajax({
    url: '/DiemDanh/testMethod',
    data: { info: JSON.stringify(dataarr ) },
    type: "POST",
    traditional:true,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (result) {
        alert('running');
    },
    error: function (data, textStatus) { alert(textStatus); }
});
}

还有我的 Controller

[HttpPost]
    public ActionResult testMethod(List<List<string>> info)
    {
        return RedirectToAction("Index");
    }

当我在 Chrome 中调试时，出现错误

POST http://localhost:56602/DiemDanh/testMethod 500 (Internal Server Error)

抱歉我的英文不好，希望大家多多指教!!!

我认为你应该改变你的javascript。二维数组应该是 [[]]

我已经为您的代码编写了一个示例。它工作正常。

function Test() {
        var dataarr = [[]];

        for (var i = 0; i < 1; i++) {
            dataarr[i][0] = "A" + i.toString();
            dataarr[i][1] = "B" + i.toString();
        }

        var model = JSON.stringify(dataarr);

        $.ajax({
            url: '/Home/testMethod',
            data: model,
            type: "POST",
            traditional: true,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (result) {
                alert('running');
            },
            error: function (data, textStatus) { alert(textStatus); }
        });
    }
