根据内容自动调整弹出窗口大小的JS解决方案

**问题
** 在弹出创苦时，根据窗口的内容来自动调节窗口的大小，窗口如果已经和屏幕相等大小时则出现滚动条。
解决方案
在弹出的页面中添加一JS脚本方法win_onLoad()，在body的onload方法中引用win_onLoad()，在body中添加表，表的id取名为tbllist，窗口的大小就是这个table的大小在宽和高上分别加50。

部分代码如下：

 1<script language="javascript">

 3![](http://www.cnblogs.com/Images/OutliningIndicators/None.gif) var  width  =  document.all[  "  tblKsList  "  ].offsetWidth;   
 4![](http://www.cnblogs.com/Images/OutliningIndicators/None.gif) var  height  =  document.all[  "  tblKsList  "  ].offsetHeight;

 6![](http://www.cnblogs.com/Images/OutliningIndicators/None.gif) width  =  eval(width  \+  50  );

12![](http://www.cnblogs.com/Images/OutliningIndicators/None.gif) width  =  screen.width;

15![](http://www.cnblogs.com/Images/OutliningIndicators/None.gif) height  =  400  ;   
16![](http://www.cnblogs.com/Images/OutliningIndicators/None.gif) else  if  (height  > screen.height)   
17![](http://www.cnblogs.com/Images/OutliningIndicators/None.gif) height  =  screen.height;
