Asp.net 在 Postback 之後 執行 javascript 方法

來源:互聯網

主要介紹如下三種方式,分別表現在3個Button的Click事件中,代碼如下:

前台:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="RunJSFunctionAfterPostBack.aspx.cs" Inherits="EricSunWebAppProject.RunJSFunctionAfterPostBack" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">    <title></title>    <script src="Scripts/jquery-1.9.0.min.js"></script></head><body>    <form id="form1" runat="server">        <asp:ScriptManager ID="Scriptmanager1" runat="server" />        <div>            <asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button1_Click" />            <asp:Button ID="Button2" runat="server" Text="Button2" OnClick="Button2_Click" />            <asp:Button ID="Button3" runat="server" Text="Button3" OnClick="Button3_Click" />        </div>    </form></body></html><script type="text/javascript">    function AlertMyInfo() {        alert("Hello Eric Sun.");    }</script>

【註:要能夠執行Button1中的Click方法,前台的<asp:ScriptManager ID="Scriptmanager1" runat="server" />必須加上。】

後台:

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace EricSunWebAppProject{    public partial class RunJSFunctionAfterPostBack : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {        }        protected void Button1_Click(object sender, EventArgs e)        {            string callbackJSFunction = "<script language='javascript'>function f(){AlertMyInfo(); Sys.Application.remove_load(f) ;}; Sys.Application.add_load (f);</script>";            Page.ClientScript.RegisterStartupScript(this.GetType(), "HelloKey", callbackJSFunction);         }        protected void Button2_Click(object sender, EventArgs e)        {            Response.Write("<script language=JavaScript> alert('Hello Eric Sun.'); </script>");         }        protected void Button3_Click(object sender, EventArgs e)        {            string s = "<script language=JavaScript>alert('Hello Eric Sun');</script>";            Page.ClientScript.RegisterStartupScript(this.GetType(), "HelloKey", s);         }    }}
