问题描述
我如何在页面包含母版的页面上发回服务器端的javascript值?
how can I get javascript value to server side on post back with page contains master page?
推荐答案
设置
母版页完全不相关.您应该设置一个文字，使其具有viewstate，这比创建HTML控件并在发布数据中搜索它要简单得多.The master page is utterly irrelevant. You should set a literal, so that it has viewstate, that''s a lot simpler than creating a HTML control and searching for it in the post data.
不确定Graus在说什么，所以我认为我会创建一个可行的示例.页面:
Not sure what Graus is talking about, so I thought I''d create a working example. The page:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %> <html> <body> <form id="form1" runat="server"> <div> <input runat="server" id="myData" type="hidden" /> <script language="javascript"> var field = document.getElementById("<%= myData.ClientID %>"); field.value = "javascript set this value"; </script> <asp:Button runat="server" ID="btnGo" Text="Go" /> </div> </form> </body> </html>
后面的代码:
The code behind:
namespace WebApplication1 { using System; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack) { btnGo.Text = myData.Value; } } } }
