1. 前端HTML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>HTML服务器控件</title>
<script type="text/javascript" runat="server">
//protected void Page_Load(Object sender, EventArgs e) //如果在当前页面设置Load事件, 那么.cs文件中的load的事件将会被覆盖
//{
// this.MyText.Value = "hello world!"; //设置input的默认值
//}
</script>
<style type="text/css">
#MyText
{
width:188px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<input id="MyText" type="text" runat="server" />
</form>
</body>
</html>
2.下面是.cs中的load事件, 如果页面中有Page_load事件, 那么该事件将会被覆盖 (Page_load事件→页面初始化事件)
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls; public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.MyText.Value = "我是首次加载";
}
else
{
this.MyText.Value = "我不是首次加载";
}
}
}
