如何让iframe满框架显示
把iframe放在table中，iframe的body中只有一个div，div的width和height都是100%,但四周总是空出一块，应该怎样设置，代码如下：
<tr width= "100% " height= "100% ">
<td width= "80% " height= "100% ">
<iframe id= "gps " src = "gps.html " width= "100% " height= "100% " frameborder= "0 " scrolling= "no "> </iframe>
</td>
<td style= "width:20% " height= "100% ">
<iframe id= "ov " src = "ov.html " width= "100% " height= "100% " frameborder= "0 " scrolling= "no "> </iframe>
</td>
</tr>
</table>
分页面：
<body onload= "load(); " >
<div id= "map " style= "position:absolute; left:0px; right:0px; width:100%; height:100%; ">
</div>
</body>
[解决办法]
iframe的那个页面的body设置样式{margin:0;}试试.
