我有这个 jquery post call，它以某种方式调用错误函数，即使它将数据输入数据库非常好。

<script type="text/javascript">
    $(document).ready(function () {
        $("#ExtMailCreate").click(function () {
            var url = '@Url.Action("Create")';
            var data = JSON.stringify(SaveExternalMail());
            $.ajax({
                type: "POST",
                url: url,
                data: data,
                dataType: "json",
                contentType: "application/json; charset=utf-8",
                success: function (data) {
                    $("#result").append("pass");
                },
                error: function (data) {
                    $("#result").append("error");
                }
            });
        });
    });

    function SaveExternalMail() {
        var costcentrecode = $("#CostCentreCode").val();
        var day = $("#ExtMailDatePicker").val();
        var externalMailItemID = $("#ExternalMailItemID").val();
        var externalMailLocationID = $("#ExternalMailLocationID").val();
        var quantity = $("#Quantity").val();
        return {
            CostCentreCode: costcentrecode,
            Day: day,
            ExternalMailItemID: externalMailItemID,
            ExternalMailLocationID: externalMailLocationID,
            Quantity: quantity
        };
    }
</script>

我认为问题在于指定JsonRequestBehavior.AllowGet

然后发布到方法：

$.ajax({
  type: "POST",
  url: url,

如果数据库正在填充，我们知道存储库代码正在触发。浏览器报告一个 HTTP403，闻起来像是框架抛出了一个安全异常，如果它期望响应 GET 并接收 POST，它可能会这样做。

如果您指定数据类型为 json 但无法将响应解析为 json，则 ajax 请求将进入错误块。

打开chrome并在错误块中放置一个断点并查看数据的值。将内容放在 json 验证器中并检查以确保您的响应是有效的 json。

还将成功和错误函数的方法标志更改为

success: function(data, txtStatus, jqxhr){ // code here }
error: function( jqxhr, txtStatus, errorThrown) { // code here }

然后在这些功能中放置断点，您可以检查参数并更清楚地查看发生了什么。

--更新由于您收到403错误代码，请在stackoverflow上查看此答案并检查您指向的文件夹的权限

发布 asp.net MVC 后禁止 403

也看看这个，因为你正在运行 IIS 5.1 它看起来像......它可能是相似的

在 IIS 5.2 上运行 MVC2 应用程序

尝试将控制器中的方法从 JsonResult 更改为 ActionResult

 <HttpPost()> _
    Function Create(ByVal collection As ExternalMail) As ActionResult

正如 denas 所说，您需要检查返回的 textStatus 和 errorThrown 生成的变量中的内容，因为您可以返回 200 HTTP 代码以外的其他内容，并且您的代码仍然可以正常执行（因为您报告您的记录被添加到数据库）。一个 200 HTTP 代码将触发“成功”功能，我现在不记得了，但 4xx 或 5xx 中的某些内容应该会触发“错误”功能。

这里要考虑的主要是网络服务器的 HTTP 返回代码控制在 jquery ajax 调用中触发什么函数

将您的代码更改为：

error: function( jqXHR, textStatus, errorThrown ) {
    console.log(textStatus);
    console.log(errorThrown);
}

并告诉我们你在这些 textStatus 和 errorThrown 变量中有什么。
