页面无刷新Upload File。

利用jquery.form.js的ajaxForm提交文件。

具体参考以下代码：

前台html

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="form_fileUpload.aspx.cs" Inherits="jq_form_plug.form_fileUpload" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <title>Form插件提交文件表单

    </title>

    <script src="Script/jquery-1.12.3.min.js"></script>

    <script src="Script/jquery.form.js"></script>

    <script type="text/javascript">

        $(function () {

            var options = {

                success: function (data) {

                    alert("I am here!!");

                    $("#responseText").text(JSON.stringify(data));

                }

            };

            $("#form1").ajaxForm(options);

        });

    </script>

</head>

<body>

    <form id="form1" action="ajaxOperation.ashx" method="post" enctype="multipart/form-data">

        <table>

            <tr>

                <td>附件名字:</td>

                <td>

                    <input type="text" name="fileName" /></td>

            </tr>

            <tr>

                <td>附件:</td>

                <td>

                    <input type="file" name="document" /></td>

            </tr>

            <tr>

                <td colspan="2" style="align-content: center">

                    <input type="submit" value="模拟iframe提交表单" />

                </td>

            </tr>

        </table>

    </form>

    <br />

    <span>需要在ajaxOperation.ashx文件中对ActionName是formUpload的操作进行断点观察</span>

    <br />

    <br />

    <label id="responseText"></label>

</body>

</html>
