Asp.net 在 Postback 之后 执行 javascript 方法
主要介绍如下三种方式，分别表现在3个Button的Click事件中，代码如下：
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>
【注：要能够执行Button1中的Click方法，前台的<asp:ScriptManager ID="Scriptmanager1" runat="server" />必须加上。】
后台：
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); } } }
