在主页加载之前,我需要一个来自 javascript 的值,然后想在代码中使用该值。我为此目的使用的代码是:
我已经制作了一个 test.aspx 页面。代码如下:-
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" %>
<!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>Untitled Page</title> <script type="text/javascript" language="javascript">
function GetScreenHeightAndWidth()
{
var width = screen.width;
var height = screen.height;
var object = 'Label1';
document.getElementById(object ).innerHTML=height ;
//alert(height);
'<%Session["Screensize"] = "' + height +'"; %>' ;
}
</script>
</head>
<body onload="GetScreenHeightAndWidth();" >
<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" runat="server" Text="test"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</div>
</form>
</body>
</html>
test.aspx.cs 页面的代码如下:-
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;
using System.Windows.Forms;
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Session["Screensize"] = Label1.Text;
TextBox1.Text=Session["Screensize"].ToString();
}
}
结果如下:-
768测试
结果我需要的是768和768。
有没有办法解决这个问题?
