★★100分★★火狐下窗口onresize的时候DIV的位置调整的问题
我设置了一个DIV的菜单，使它和input框下面对齐，现在在窗口尺寸变化的时候DIV的位置会跑偏，我使用了onresize来重新定位，在IE下好使，但是火狐下就不起作用有没有什么好办法能适应两种浏览器。
代码如下：
样式：
#box{ width:100px; height:100px; background-color:#999999; position:fixed;_position:absolute; top:200px; left:600px;}
JS片断：
function showdiv()
{
var divid=document.getElementById("box");
var btn=document.getElementById("q");
divid.style.left=getAbsoluteLeft(btn); //可以通过加减来控制一定的偏移量。
divid.style.top=getAbsoluteTop(btn);
}
getAbsoluteLeft = function(obj){
//获取指定元素左上角的横坐标（相对于body）
/*
obj | 指定的元素对象
*/
var selfLeft = 0;
var element = obj;
while(element){
selfLeft = selfLeft + element.offsetLeft;
element = element.offsetParent;
};
return selfLeft;
}
getAbsoluteTop = function(obj){
//获取指定元素左上角的纵坐标（相对于body）
/*
obj | 指定的元素对象
*/
var selfTop = 0
var element = obj;
while(element){
selfTop = selfTop + element.offsetTop;
element = element.offsetParent;
};
return selfTop;
}
HTML片断:
<body onload="showdiv();" onresize="showdiv()">
<div id="box" style="display:none">
<table border="0" width="80%" cellspacing="1" >
<tr>
<td align="rgiht" nowrap>
<font color="#ffffff">检索词：</font>
</td>
<td align="left" width="100">
<input type="text" size="65" name="q" id="q" />
</td>
<td align="left">
<input type="image" src="/images/button_search_1.gif"/>
</td>
</tr>
</table>

如果你用过jquery的话，下面这段代码可能对你有用：
