★★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>
  &nbsp;
  <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">&nbsp;&nbsp;  
  <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:
