網頁編程如果想要和使用者進行互動，我知道的就是用alert() 這種方式有時候還好，感覺不太友好呀。但是Extjs的那個提示效果非常好，大家可以再進行擴充。
昨天晚上做了個例子，就是Asp.net從後台調用前台的js代碼的。
代碼如下所示：
<%@ 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></title> <link rel="stylesheet" type="text/css" href="extjs/resources/css/ext-all.css"/> <script type="text/javascript" src="extjs/adapter/ext/ext-base.js"></script> <script type="text/javascript" src="extjs/ext-all.js"></script> <script type="text/javascript" src="extjs/src/locale/ext-lang-zh_CN.js"></script> <script type="text/javascript" src="Main.js"> </script></head><body> <form id="form1" runat="server"> <div> <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" /> </div> </form></body></html>
js代碼：
function ConfirmRelogin() { alert("dddd");};function hello() { Ext.onReady(function () { //alert("1111"); Ext.MessageBox.alert("提示", "登出登入成功"); });};
後台代碼：
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) { } protected void Button1_Click(object sender, EventArgs e) { ClientScript.RegisterStartupScript(ClientScript.GetType(), "myscript", "<script>hello();</script>"); }}
效果如下所示：
