在我的应用程序中，我有一个编辑个人资料页面，您可以在下面看到；

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.master" 
Inherits="System.Web.Mvc.ViewPage<SHP.WebUI.Models.EmployeeViewModel>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Edit
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <% using (Html.BeginForm("Edit", "Employee"))
    {%>
        <%: Html.AntiForgeryToken()%>
        <%: Html.ValidationSummary(true)%>
        <fieldset>
            <legend>Edit Employee</legend>
             <% if (TempData["Message"] != null && TempData["Message"].ToString().Length > 0)
             { %>
                <p class="success">
                   At <% Response.Write(DateTime.Now.ToString("T")); %> 
                   you entered <%: TempData["Message"]%>.
                </p>
             <%} %>
            <table class="groupBorder" id="editTable">
                <tr>
                    <td style="text-align: right;"><%: Html.LabelFor(model => model.Employee.CompanyId)%></td>
                    <td>
                        <%: Html.DropDownListFor(model => model.Employee.CompanyId, Model.CompaniesSelectList)%>
                    </td>
                </tr>
                <tr>
                    <td style="text-align: right;">
                <%: Html.LabelFor(model => model.Employee.EmployeeNumber)%>
                   </td>                    
                    <td>
                <%: Html.TextBoxFor(model => model.Employee.EmployeeNumber,
                    new { maxlength = "4", style = "width:35px;text-transform: uppercase;" })%>
                <%: Html.ValidationMessageFor(model => model.Employee.EmployeeNumber)%>
                    <span class="error" id="errorMessage">
                        <% if (TempData["ErrorMessage"] != null)
                        { %>
                            <%: TempData["ErrorMessage"].ToString()%>
                        <% } %>
                    </span>
                    </td>
                </tr>

                <tr>
                    <td style="text-align: center;padding-top:20px;" colspan="2">
                    <input type="submit" value="Save"  id="btnSubmit"/></td>
                </tr>
            </table>
        </fieldset>

    <% } %>

    <div>
        <%: Html.ActionLink("Back to List", "List")%>
    </div>

    <script language="javascript" type="text/javascript">


        $(document).ready(function() {


            $("#Employee_CompanyId").change(function () {
                validateEmployeeNumber();
            });

            $("#Employee_EmployeeNumber").change(function () {
                validateEmployeeNumber();
            });
        });

        function validateEmployeeNumber() {
            var employeeNumber = $("#Employee_EmployeeNumber").val().toUpperCase();
            $("#Employee_EmployeeNumber").val(employeeNumber);
            if (employeeNumber.length == 0) {
                $('#errorMessage').text("Employee Number Required");
            }
            if (employeeNumber.length > 0) {
                $('#errorMessage').text('');
                $('#btnSubmit').attr("disabled", false);
                var companyId = $("#Employee_CompanyId").val();
                var employeeId = $("#Employee_EmployeeId").val();
                $.ajax({
                    data: { companyId: companyId, employeeNumber: employeeNumber, employeeId: employeeId },
                    dataType: "text",
                    success: function (data) {
                        if (data.length > 0) {
                            $('#errorMessage').text(data);
                            $('#btnSubmit').attr("disabled", true);
                        }
                    },
                    type: "POST",
                    url: '<%= Url.Action("ValidateEmployeeNumber", "Employee")%>'
                });
            }
        }
        </script>


</asp:Content>

这里使用的控制器如下；

   [HttpPost]
    [Authorize(Roles = "Administrator, ManagerAccounts, ManagerIT")]
    public string ValidateEmployeeNumber(string companyId, string employeeNumber, string employeeId = null)
    {
        var cid = 0;
        var flag = int.TryParse(companyId, out cid);
        if (!flag)
        {
            return string.Empty;
        }

        var eid = 0;
        if (employeeId != null)
        {
            flag = int.TryParse(employeeId, out eid);
            if (!flag)
            {
                return string.Empty;
            }
        }

        if (Employee.ValidateEmployeeNumberFormat(employeeNumber) == false)
        {
            return "Invalid format";
        }

        var employeeNumberExists = Employee.GetEmployeeByEmployeeNumber(cid, employeeNumber, eid);
        return employeeNumberExists ? "Invalid Employee Number already in use." : string.Empty;
    }

此页面本身已被编辑以显示我感兴趣的位。该页面使管理员能够编辑员工的个人资料，包括员工编号。对服务器的 Ajax 调用是为了检查员工编号是否唯一。现在在我的开发人员机器上，这适用于所有服务器；开发、测试和生产。但是对于一些在其他机器上工作的人来说，它不起作用。当他们尝试在生产服务器上编辑员工编号时，突然在 AJAX 调用后立即出现大量红色的 javascript 文本。为什么会发生这种情况，如何解决？

我找到了答案。该问题是由控制器方法上的授权属性引起的。这个属性排除了一些用户，当他们使用 Ajax 服务时，他们得到了这个错误。我不得不说问题的症状，屏幕上显示的大量红色 javascript 文本，并没有给出任何问题可能是什么。
