1. FCKeditor
I used FCKeditor all the time. However, after rails was upgraded, FCKeditor had a problem and failed to handle it for a long time. In addition, FCKeditor was slow and decided to give up.
2. ckeditor 3.0.
It is the new name of FCKeditor. The latest version is beta2, and the interface is not changed much. However, the image upload function is not available yet.

3. Change Sina or Netease Editor

After downloading and modifying it, you can use it in rails2.3.2, but the editorCode(HTML) does not contain the DIV label. This problem has left me two or three days to find out why it is Div. It is normal to remove an outer Div, but my page must contain Div, you can only give up.
4. kindeditor
Later found: http://code.google.com/p/kindeditor/downloads/list
However, it does not support rails directly. You need to write some code by yourself.
Kindeditor is easy to use now.
