推荐答案
维诺德，
我创建了两个函数，可在页面加载过程中使用客户端单击按钮从服务器和客户端获取日期和时间.
注意:请不要在页面加载期间调用服务器按钮事件，否则它将卡住，因为这种情况如下:
1.页面已加载
2.按钮单击事件是从客户端调用的，它将再次创建回发
3.再次进行页面加载调用....
这是HTML代码:
Hi Vinod,
I have created two function to get Date and Time from Server and Client using button click from client side during page loading.
Note: Please don''t call server button event during page loading other wise it will stuck because the scenario like:
1. Page is load
2. Button click event is calling from client side, it will again creating a post back
3. Again page load call....
Here is HTML code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ZTest2.aspx.cs" Inherits="ZTest2" %>
<!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 language="javascript" type="text/javascript">
function getServerTime() {
var btnServer = document.getElementById('<%=btnGetTime.ClientID %>');
btnServer.click();
}
function clientClick() {
var btnClient = document.getElementById('btnClient');
btnClient.click();
}
function getClientTime() {
var clientText = document.getElementById('<%=txtClientTime.ClientID %>');
var dt = new Date();
clientText.value = dt.getDate() + "-" + dt.getMonth() + "-" + dt.getFullYear() + " " + dt.getHours() + ":" + dt.getMinutes() + ":" + dt.getSeconds();
}
function pageLoadFunction() {
clientClick();
//getServerTime();
}
</script>
</head>
<body onload="pageLoadFunction();">
<form id="form1" runat="server">
<table cellpadding="0" cellspacing="0" width="100%">
<tr>
<td align="center">
<table cellpadding="2" cellspacing="2">
<tr>
<td>
Getting server time using Javascript
</td>
<td>
<asp:TextBox runat="server" ID="txtServerTime"></asp:TextBox>
</td>
<td>
<asp:Button runat="server" ID="btnGetTime" Text="Get Server Time" OnClick="btnGetTime_Click" />
</td>
</tr>
<tr>
<td>
Getting client time using Javascript
</td>
<td>
<asp:TextBox runat="server" ID="txtClientTime"></asp:TextBox>
</td>
<td>
<input type="button" id="btnClient" value="Get Client Time" onclick="getClientTime();" />
</td>
</tr>
</table>
</td>
</tr>
</table>
</form>
</body>
</html>
这是服务器端代码:
Here is server side code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class ZTest2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnGetTime_Click(object sender, EventArgs e)
{
txtServerTime.Text = DateTime.Now.ToString("dd-MMM-yy hh:mm:ss");
}
}
如有任何疑问，请让我知道.

您的意思是页面加载时的按钮点击事件.
非常简单
您可以从页面加载中调用按钮点击事件.
请参阅以下代码.
you mean button click event on page load.
its very simple
you can call button click event from page load.
see the below code.
<form id="form1" runat="server">
<div>
<asp:Button ID="btn" Text="Submit" runat="server" onclick="btn_Click" />
</div>
</form>
protected void Page_Load(object sender, EventArgs e)
{
btn_Click(sender, e);
}
protected void btn_Click(object sender, EventArgs e)
{
Response.Write("button click event executed");
}
简单..
创建一个单独的方法，例如MyMethod().在Page_Load以及Button Click Event下调用此方法！
问题已解决:)
Simple..
Create a separate method say MyMethod(). call this method in Page_Load and also under the Button Click Event !!
Problem solved :)
