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()");
        }
