在两个页面之间互相写其控件内的值

定义A页面,定义TextBox id="TextBox1"和Button id="Button1"
后台代码:

private void Page_Load(object sender, System.EventArgs e)
        {
            this.Button1.Attributes.Add("onclick","window.open('SelectData.aspx?rec=TextBox1','newwin','toolbar=no,menubar=no,status=no,location=no,resizable=no,scrollbars=no,width=218,height=185,top=190,left=300');return false;");
        }

定义界面B:  TextBox id="TextBox1"和Button id="Button1" 和type="hidden" id="name"
脚本:

<SCRIPT language="JavaScript">
            var parwindow;
            parwindow=self.opener;
            var recv = document.all("name").value;
            if (parwindow != null) 
            {
            document.all("TextBox1").value=parwindow.document.all(recv).value;
            }
            
            function changetext() 
            {
                if (parwindow != null) 
                {
                    try{
                            parwindow.document.all(recv).value = document.all("TextBox1").value;
                        }
                    catch(e)
                        {
                        }
                 }
            }
        </SCRIPT>

 

放在form后
后台代码:

private void Page_Load(object sender, System.EventArgs e)
        {
            name.Value = Request.QueryString[0];
            this.Button1.Attributes.Add("onclick","changetext();window.close()");
        }
