fck高度自适应插件

打开插件所在文件：/editor/plugins/autogrow/fckplugin.js
找到第65行：
window.frameelement.height = imainframesize ;
将其修改为：
代码如下:

这样就可以兼容ie和火狐浏览器了。
启用插件：
打开文件：/fckeditor/fckconfig.js
启用这两行：
fckconfig.plugins.add( "autogrow" ) ;
fckconfig.autogrowmax = 600 ;
autogrowmax是限制最高高度。可以根据需要自行设置。

function fckautogrow_check()
{
   var oinnerdoc = fck.editordocument ;

   var iframeheight, iinnerheight ;

   if ( fckbrowserinfo.isie )
   {
      iframeheight = fck.editorwindow.frameelement.offsetheight ;
      iinnerheight = oinnerdoc.body.scrollheight ;
   }
   else
   {
      iframeheight = fck.editorwindow.innerheight ;
      iinnerheight = oinnerdoc.body.offsetheight ;
   }

   var idiff = iinnerheight - iframeheight ;

   if ( idiff != 0 )
   {
      var imainframesize = window.frameelement.offsetheight ;

      if ( idiff > 0 && imainframesize < fckconfig.autogrowmax )
      {
         imainframesize += idiff ;
         if ( imainframesize > fckconfig.autogrowmax )
            imainframesize = fckconfig.autogrowmax ;
      }
      else if ( idiff < 0 && imainframesize > fckautogrow_min )
      {
         imainframesize += idiff ;
         if ( imainframesize < fckautogrow_min )
            imainframesize = fckautogrow_min ;
      }
      else
         return ;

      window.frameelement.height = imainframesize;
      window.frameelement.style.height = imainframesize+"px";

      // gecko browsers use an onresize handler to update the innermost
      // iframe"s height. if the document is modified before the onresize
      // is triggered, the plugin will miscalculate the new height. thus,
      // forcibly trigger onresize. #1336
      if ( typeof window.onresize == "function" )
         window.onresize() ;
   }
}
