为什么我的IE不执行javascript:window.open()这样的语句

window.open("load.aspx","","fullscreen=0,toolbar=0,location=0,directories=0,alwaysLowered=0,dependent=0,status=0,menubar=0,scrollbars=0,resizable=0,height=300,width=500,top=220,left=220,align=center",false);

        window.opener=""; //不会出提示框了

        window.close();
