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);
}
