javascript 跨域子窗口关闭并刷新父窗口

在父窗口调用open时作如下处理：

function winOpen(url)
        {
            var win=window.open(url,'','height=400,width=650,top=300,left=300,toolbar=no,menubar=no,scrollbars=yes,resizable=yes,location=no,status=no');  
            setInterval((function(win){return function(){  
                                    if(win.closed){  
                                        window.location.reload();  
                                    }  
                        };})(win),1000); 
        }
