javascript - jQuery ajax 调用 mvc Action 不会触发成功/错误

Question

尝试为全局 session 变量创建开关时，ajax 调用永远不会返回“成功”或“错误”。

调用操作并设置 session 键，但永远不会触发成功/错误函数。

这很奇怪，因为我使用与其他调用相同的结构来替换 div 并且它有效。

Javascript 不起作用

function SwitchHelpMode() {
    debugger;
    var helpmode = true;
    $.ajax({
        type: 'GET',
        url: '/Session/GetSessionKey',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        data: { key: "helpmode" },
        sucess: function (data) {
            alert(data);
            //debugger;
            //var ok = data.success;
            //if (ok) {
            //    var algo = data.value;
            //    alert(algo);
            //    helpmode = !algo;
            //}
        },
        error: function (xhr) {
            //debugger;
            alert(xhr);
            alert('ERROR::SetSessionKey!' + xhr.responseText);
        }
    });
    helpmode = false;
    $.ajax({
        type: 'GET',
        url: '/Session/SetSessionKey',
        data: { key: "helpmode", value: helpmode },
        sucess: function (data) {
            alert(data);
        },
        error: function (xhr) {
            debugger;
            alert('ERROR::SetSessionKey!' + xhr.responseText);
        }
    });
}

Controller

public ActionResult SetSessionKey(string key, string value)
{
    Session[key] = value;

    return Json(new { success = true }, JsonRequestBehavior.AllowGet);
}

public ActionResult GetSessionKey(string key)
{

    if(Session[key] != null)
    {
        var value = Session[key];

        return Json(new { success = true, data = value }, JsonRequestBehavior.AllowGet);
    }
    else
    {
        return Json(new { success = false }, JsonRequestBehavior.AllowGet);
    }
}

Javascript 有效

function FilterInfoByFlightsCallback(values) {
    //debugger;
    var data = JSON.stringify(values);
    var url = '/Campaign/FilterInfoByFlights';
    $.ajax({
        type: 'GET',
        url: url,
        data: { filter: data },
        success: function (result) {
            $('#infoList').html(result);
        },
        error: function (result) {
            // handle errors
            location.href = "/MindMonitor/"
        }
    });
}

{"success":true,"data":"false"}

有什么想法吗？

Answer 1

因此，即使服务器的响应为 200 OK，success: function (data) { 中也没有额外的 c > 但它不会触发传统的成功，因为它无法找到一个。

应该是 - 成功:函数(数据){
