• 页面无刷新提交数据


    ajax无刷新提交数据不是新技术了,只是最近才用到,做了个小程序与新手分享,也备自己以后查阅。

    Default.aspx页面代码: 

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        
    <title>测试</title>

        
    <script type="text/javascript" src="http://www.w3school.com.cn//jquery/jquery.js"></script>

        
    <script type="text/javascript">
    $(document).ready(
    function(){
       $(
    "#btnstop").click(function() {
            $(
    "#btnstop").attr('disabled'true);
            $(
    "#btnstop").val("发送中...");
            
    var numbers =$("#listbox").html(); //号码

            
    if (numbers == "") {
                alert(
    "没有选择号码!");
                $(
    "#btnstop").attr('disabled'false);
                $(
    "#btnstop").val("停止");
                
    return false;
            }
    $.ajax({
                    url: 
    'Submits.ashx',
                    type: 
    'post',
                    timeout: 
    '1500000',
                    data: 
    "&n=" + numbers ,
                    error: 
    function() {
                        alert(
    "数据传输错误!请重新提交");
                        $(
    "#btnstop").attr('disabled'false);
                        $(
    "#btnstop").val("停止");
                    },
                    success:

                            }
                            
                            
    else {
                                cc 
    = data;
                            }
                            $(
    "#btnstop").attr('disabled'false);
                            $(
    "#btnstop").val("停止");
                            $(
    "#result").html("报告:"+cc);
                            setTimeout(
    function(){document.all.result.innerHTML +='<p/>间隔2秒'},2000);
                            setTimeout(
    function(){document.all.result.innerHTML +='<p/>间隔4秒'},4000);
                        }
                    }
                });

    i

    document.all.listbox.innerHTML

    Submits.ashx后台代码:

     1 <%@ WebHandler Language="C#" Class="Submits" %>
     2 
     3 using System;
     4 using System.Web;
     5

     9 
    10         string numbers = HttpUtility.UrlDecode(context.Request.Form["n"]);//号码
    11 
    12         context.Response.ContentType = "text/plain";
    13         context.Response.Write("号码"+ numbers + "已经提交至服务器.");
    14         //context.Response.Write("error");
    15         context.Response.End();
    16     }
    17  
    18     public bool IsReusable {
    19         get {
    20             return false;
    21         }
    22     }
    23
