Question

我有这个AJAX帖子功能：

var library = {
    ajaxPost: function (endpoint, data, callback, returnSelector, dataType, type) {
        $.ajax({
            type: (type ? type : "POST"),
            url: endpoint,
            data: data,
            dataType: (dataType === undefined ? "JSON" : dataType),
            success: function (result) {
                if (callback != null && callback !== undefined) {
                    callback(returnSelector === false ? result : $(result));
                }
                console.log("endpoint = " + endpoint);
                console.log("data = " + data);
                console.log("callback = " + callback);
                console.log("returnSelector = " + returnSelector);
                console.log("dataType = " + dataType);
                console.log("type = " + type);
                console.log("result = " + result);
            },
            error: function (xhr, ajaxOptions, thrownError) {
                // show an error message
                console.error(xhr.status);
                console.error(thrownError);
            },
            complete: function () {
            }
        });
    }
};

这就是调用函数的地方：

var modalCallbacks = {
    companyCreate: function (result, modalDom) {
        callModalBasicInit();

        var saveButton = modalDom.find(".modal-footer button[type='submit']");
        saveButton.unbind("click");

        saveButton.on("click", function (e) {
            e.preventDefault();

            var data = modalDom.find("form").serializeObject();
            data["returnJson"] = true;

            library.ajaxPost("/companies/edit/", data, function (result) {
                if (result.success) {
                    modalDom.modal('hide');

                    var dropdown = $("#create-modal #CompanyID");
                    var currentSelected = dropdown.find("option:selected");
                    if (currentSelected.length) {
                        currentSelected.removeAttr("selected");
                    }

                    var newOption = '<option value="' + result.company.CompanyID + '">' + result.company.Name + '</option>';
                    dropdown.append(newOption);
                    dropdown.val(result.company.CompanyID);
                }
            }, false);
        });
    }
}

我的问题是你在if语句中看到的jQuery：if(result.success) { }永远不会被执行。我有console.logged result.success它出现了undefined，我意识到这是问题的主要部分，但我怎么能让它返回true？其他所有功能都按预期运行，数据将保存到数据库中。

我在控制台中记录了一些内容：

endpoint = /companies/edit/
data = [object Object]
callback = function (result) {
                    if (result.success) {
                        modalDom.modal('hide');

                        var dropdown = $("#create-modal #CompanyID");
                        var currentSelected = dropdown.find("option:selected");
                        if (currentSelected.length) {
                            currentSelected.removeAttr("selected");
                        }

                        var newOption = '<option value="' + result.company.CompanyID + '">' + result.company.Name + '</option>';
                        dropdown.append(newOption);
                        dropdown.val(result.company.CompanyID);
                    }
                }
returnSelector = false
dataType = undefined
type = undefined
result = [object Object]

AJAX后回调不起作用
