JQuery在asp.net中三种ajax传值

1)通过webservice,注意去掉注释[System.Web.Script.Services.ScriptService]这行前的注释

2)通过aspx.cs文件中的静态方法

3)通过aspx文件url

WebForm1.aspx

<body>

</div>
<div>
<input id="Button3" type="button" value="jquery通过page存储值" onclick="FromPage()" />

以上是启动页面,WebForm1.aspx.cs没有代码

namespace asp.net
{
/// <summary>

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务,请取消对下行的注释。
[System.Web.Script.Services.ScriptService]
public class WebService1 : System.Web.Services.WebService
{

[WebMethod]
public string HelloWorld()
{
return "Hello World"+System.DateTime.Now.ToLongTimeString();
}

[WebMethod]
public string HelloWorld2(string name)
{
return "Hello World" + name + System.DateTime.Now.ToLongTimeString();
}
}
}

以上是webservice中的代码

aspxpage.aspx.cs

namespace asp.net

public partial class aspx页面代替ws : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
[WebMethod]
public static string SayHello()
{
return "Hello";
}

[WebMethod]
public static string SayHello2(string name)
{
return "Hello"+name;
}
}
}

以上是针对第二条 通过aspx.cs中的静态方法 注意方法前要加 [WebMethod],aspxpage.aspx页面没代码.

dataContent.aspx.cs

{
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
Page.ViewStateMode = ViewStateMode.Disabled;
if (Request.QueryString["nowtime"] != null)
{
string stime = Request.QueryString["nowtime"].ToString();
Response.Write(stime);
}
Response.Flush();

}
}
}

以上是针对第三条 用url传值 通过aspx页面保存数据。dataContent.aspx页面没有代码.
