怎么做一个随页面自动弹出的居中窗口？

再弹出的页面上加上
<script language="JavaScript">
top.moveTo(screen.availWidth/4,screen.availHeight/4);
top.resizeTo(screen.availWidth/2,screen.availHeight/2);
</script>

window.open好像是可以自动加弹出的位置的？

[wlboy110]

<script language='JavaScript'>
window.open('kkk','','height=500,width =500,top=168,left=326,location =0,menubar =0,resizable=0,scrollbars =0,status =0,toolbar =0,titlebar =0')
</script>

怎么写成弹出是居中的窗口呢？
