使用JavsScript客户端调用服务器端的非静态方法 [英] Call non-static method in server-side from client-side using JavsScript
问题描述
我如何使用JavaScript（Java）调用从客户端服务器端（aspx.cs）非静态方法....？
How do I call a non-static method in server side(aspx.cs) from client side using javascript (aspx)....?
据我知道我可以从客户端调用静态方法在服务器端...
As far as I know I can call static method in server side from client side...
服务器端：
[WebMethod]
public static void method1()
{
}
客户端：
<script language="JavaScript">
function keyUP()
{
PageMethods.method1();
}
</script>
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
</asp:ScriptManager>
它的工作原理。现在怎么办我称之为非静态方法从客户端？
It works. Now how do I call non-static method from client side?
推荐答案
您可以通过使用简单的.asmx页，而不是codebehind页避免静电约束。
You can avoid the static constraint by using a simple .asmx page instead of the codebehind page.
1）使用AJAX启用ASP.NET模板（它把必要的引用在web.config）打开新的网站
1) Open New Website using the AJAX Enable ASP.NET template (it puts the necessary references in the web.config)
2）SIMPLESERVICE.ASMX - 添加一个新的.asmx Web服务（我叫雷SimpleService.asmx）
注意[System.Web.Script.Services.ScriptSerive]装修的SimpleService类实现Webservice的。
2) SIMPLESERVICE.ASMX - Add a new .asmx web service (I called mine SimpleService.asmx) Notice the [System.Web.Script.Services.ScriptSerive] decoration and that the SimpleService class implements Webservice.
<%@ WebService Language="C#" Class="SimpleService" %>
using System;
using System.Web.Services;
[System.Web.Script.Services.ScriptService]
public class SimpleService : WebService
{
[WebMethod]
public string GetMessage(string name)
{
return "Hello <strong>" + name + "</strong>, the time here is: " + DateTime.Now.ToShortTimeString();
}
}
3）的Default.aspx - 要使用它引用的服务于你的脚本经理，你是关闭和运行。在我的javascript我称之为class.method - SimpleService.GetMessage
3) DEFAULT.ASPX - To use it reference the service in you script manager and you are off and running. In my Javascript I call the class.method - SimpleService.GetMessage.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
<script language="javascript" type="text/javascript">
function callServer() {
SimpleService.GetMessage($get("Name").value, displayMessageCallback);
}
function displayMessageCallback(result) {
$get("message").innerHTML = result;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" >
<Services>
<asp:ServiceReference Path="~/SimpleService.asmx" />
</Services>
</asp:ScriptManager>
<div>
</div>
<h1>Hello World Example</h1>
<div>
Enter Name: <input id="Name" type="text" />
<a href="javascript:callServer()">Call Server</a>
<div id="message"></div>
</div>
</form>
</body>
</html>
我用我从斯科特谷发现的例子
