window.open页面关闭后刷新父页面

如题

function openWin(url,text,winInfo){  
    var winObj = window.open(url,text,winInfo);  
    var loop = setInterval(function() {       
        if(winObj.closed) {      
            clearInterval(loop);      
            //alert('closed');      
            parent.location.reload();   
            //window.location.reload();  刷新当前页面
        }      
    }, 1);     
}
