一，JS动态创建表单

var result = "   <form method='post' action='../xiazai.aspx'><table width='100%' border='0' cellpadding='0' cellspacing='1' bgcolor='#BDB4A2'>"+
                "<tr>"+
                  "<td width='40' height='40' bgcolor='#CCC0AA'> </td>"+
                  "<td colspan='3' align='center' bgcolor='#F3EDDD' class='font_14'>共生成"+arrCon[1]+"注选号，共计"+(Number(arrCon[1])*2)+"元。</td>"+
                  "<td width='40' bgcolor='#CCC0AA'> </td>"+
                "</tr>";
             result += "<tr><td height='40' bgcolor='#CCC0AA'> </td>";
             var content = arrCon[0];
             var array = content.split(";");
             for(var i=0;i<array.length;i++){
             result += " <td align='center' bgcolor='#FEFBF4'><span class='ft166C5'> <input name='txt1' type='hidden' value='"+array[i]+"/t/n' /> "+array[i]+" </span></td>"
             if((i+1)%3 == 0){
               result += "<td bgcolor='#CCC0AA'></td></tr><tr><td height='40' bgcolor='#CCC0AA'> </td>"
             }
             }
              result+= "</tr></table> <input id='Submit1' type='submit' value='保存到本地'/></form>";

二 aspx.cs代码实现动态打印

    protected void Page_Load(object sender, EventArgs e)
    {
       // ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('" + Request.Form["txt1"] + "')</script>");
        string FileName = "彩讯网----彩票缩水";
        Response.ContentType = "Application/octet-stream";
        Response.AppendHeader("Content-Disposition", "attachment;filename=/"" + System.Web.HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8) + ".txt/"");
        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
        Response.Write(Request.Form["txt1"]);
        Response.Flush();
        Response.End();
        ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('文件下载成功')</script>");
    }
