用window.openr打开的子父窗口之间的操作跟框架的是不一样的，子窗口和父窗口之间有opener来联系。而源窗口要访问子窗口要通过其句柄来操作。以下小例子希望能帮助新手更了解他们的操作。

<script>
var win=null;
function op(){
win=window.open("about:blank","win","width=200,height=200");
win.document.write("<input type='button' value='关闭父窗口' onclick='window.opener.opener=null;window.opener.close()'>");
win.document.write("<input type='button' value='刷新你窗口' onclick='window.opener.location.reload()'>");
}
</script>
<input onclick="op()" value="打开窗口" type="button"><input type="button" value="最小化" onclick="if(win&&win.open&&!win.closed){win.resizeto(0,0);win.moveto(0,window.screen.width);}else alert('还没有打开窗口或已经关闭')"><input type="button" value="最大化" onclick="if(win&&win.open&&!win.closed){win.moveto(-4,-4);win.resizeto(screen.availwidth+8,screen.availheight+8);}else alert('还没有打开窗口或已经关闭');"><input type=button value="关闭子窗口" onclick="if(win&&win.open&&!win.closed){win.opener=null;win.close()}else alert('还没有打开窗口或已关闭')"><input type=button value="刷新子窗口" onclick="if(win&&win.open&&!win.closed){win.location.reload();win.focus()}else alert('窗口还没有打开或已关闭')"><input type="button" value="看子窗口的大小" onclick="if(win&&win.open&&!win.closed){alert(win.document.body.clientwidth+'*'+win.document.body.clientheight);win.focus();}else{alert('还没有打开窗口或者已关闭')};">
</body>
</html>
运行效果如下：
