常用的ajax就不讲了,这里主要是说通过ajax调用asp.net后台的cs文件暴露的方法.
前台:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1.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 id="Head1" runat="server">
<title></title>
<script src="Scripts/jquery-1.4.2.js" type="text/javascript"></script>
<script type="text/javascript">
$("input[type='button'][value='GetOneDayLater']").click(function () {
$.ajax({
type: "post",
url: "Default.aspx/GetOneDayLate",
data: "{days:1}",
datatype: "json",
contentType: "application/json; charset=utf-8",
success: function (data) {
$("input#showTime").val(eval('(' + data.d + ')')[0].nowtime);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(errorThrown);
}
});
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="button" value="GetOneDayLater" />
<input type="text" id="showTime" />
</div>
</form>
</body>
</html>
后台:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Services;
namespace WebApplication1
{
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
[WebMethod]
public static String GetOneDayLate(Int32 days)
{
return "[{"nowtime":"" + DateTime.Now.AddDays(days).ToShortDateString() + ""}]";
}
}
}
