  • ajax实现文件下载

    前台:

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
        <title></title>
        <script src="../../Lib/jquery.js"></script>
        <script>
            $(document).ready(function ()
            {
                $("#Button1").click(function ()
                {
                    location.href = 'Web7.ashx'
                });
            });
        </script>
    </head>
    <body>
        <form id="form1" runat="server">
        <div>
            <input id="Button1" type="button" value="下载" />
        </div>
        </form>
    </body>
    </html>

    一般处理程序

            string s_fileName = "交代事项需求.docx";
                HttpContext.Current.Response.ContentType = "application/ms-download";
                string s_path = HttpContext.Current.Server.MapPath( s_fileName ) ;
                System.IO.FileInfo file = new System.IO.FileInfo( s_path );
                HttpContext.Current.Response.Clear( );
                HttpContext.Current.Response.AddHeader( "Content-Type" , "application/octet-stream" );
                HttpContext.Current.Response.Charset = "utf-8";
                HttpContext.Current.Response.AddHeader( "Content-Disposition" , "attachment;filename="
              + System.Web.HttpUtility.UrlEncode("abc.docx" , System.Text.Encoding.UTF8 ) );
                HttpContext.Current.Response.AddHeader( "Content-Length" , file.Length.ToString( ) );
                HttpContext.Current.Response.WriteFile( file.FullName );
                HttpContext.Current.Response.Flush( );
                HttpContext.Current.Response.Clear( );
                HttpContext.Current.Response.End( );
