Question

我收到成功警报，但更新日期的功能不会运行。我错过了什么这是我第一次尝试这个。 acquiredate和DefendantID都有值。

这是aspx页面上的代码：

<script type="text/javascript">

    $(function () {
        $("[id*=textboxAcquiredDate]").change(function () {
            var AcquiredDate = $(this).val();
            var DefendantID = $(this).attr("DefendantID");

                $.ajax({
                    type: "POST",
                    url: "Defendants.aspx/acquireddate_update",
                    data: "{'DefendantID' : '" + DefendantID + "', 'AcquiredDate' : '" + AcquiredDate + "'}",
                    contentType: "application/json;charset=utf-8",
                    dataType: "json",
                    error: function (response) {
                        alert("error.");
                    },
                    success: function (response) {
                        alert("update successful.");
                    }
                });
            return false;
        });
    });

</script>

这是aspx.vb文件中的代码（此函数未运行）：

<WebMethod()>
<ScriptMethod()>
Public Shared Sub acquireddate_update(DefendantID, AcquiredDate)

    Dim stringCommand As String = "UPDATE dbo.Defendant SET AcquiredDate=@AcquiredDate WHERE DefendantID=@DefendantID;"
    Using con As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("connectionstringdev").ConnectionString)
        Dim cmd As New SqlCommand(stringCommand, con)
        cmd.CommandType = Data.CommandType.Text
        With cmd.Parameters
            .AddWithValue("@DefendantID", DefendantID)
            .AddWithValue("@AcquiredDate", AcquiredDate)
        End With
        con.Open()
        cmd.ExecuteNonQuery()
    End Using

End Sub

在RouteConfig.vb文件中，我注释掉了这一行：

settings.AutoRedirectMode = RedirectMode.Permanent

现在它正在运作！

使用jquery使用ajax，POST，json。我获得了成功，但POST似乎没有运行
