Question

我试图通过创建ajax调用从aspx页面调用aspx.cs中的方法。然而，响应为0.一些研究引导我验证ajax调用中的数据类型和数据，但没有一个解决了问题。是否会有一个窗口失去焦点，这可能导致调用是UNSENT？

<script>
        function blah(e) {
        var url = 'Default.aspx/Test';

        selectedFiles = document.getElementById("MainContent_file1");
        var file = selectedFiles.files[0];
        var reader = new FileReader();
        reader.onload = function (e) {

            var encrypted = CryptoJS.AES.encrypt(reader.result, '12345');
            encrypted = encodeURIComponent(encrypted);
            var encryptedFile = new File([encrypted], file.name + '.encrypted', { type: "text/plain", lastModified: new Date() });

            var formData = new FormData();
            formData.append('myFile', encryptedFile)
            //data.append('file[0]', encryptedFile);
            debugger;
            $.ajax({
                type: "POST",
                data: {'aa': encryptedFile},
                //data: encrypted,
                cache: false,
                contentType: false,
                dataType: 'json',
                processData: false,
                url: "Default.aspx/Test",
                success: function (response) {
                    debugger;
                    alert(response);
                },
                error: function (xhr, textStatus, error) {
                    debugger;
                    alert(xhr.statusText);

                }
            });
        };

        reader.readAsDataURL(file);

    }

</script>

ASPX.CS

 protected void Page_Load(object sender, EventArgs e)
      {

      }

    [WebMethod()]
    public static string Test(object aa)
    {
       return "Hello";
    }

错误讯息：

xhr = Object {readyState: 0, responseText: "", status: 0, statusText: "error"}, textStatus = "error", error = ""

详细回复：Default.aspx：

Request URL:http://localhost:51936/Default.aspx
Request Method:POST

测试：

Request URL:http://localhost:51936/Default.aspx/Test

jQuery ajax对codebehind方法的POST调用返回XHR状态0
