这个页面里这样的
&FCK:editor id="info_demo" basePath="../fckeditor/" width="100%" height="500"
toolbarSet = "Default" &
&/FCK:editor&
&input type="hidden" name="info_demo" value=""&
&script language="javascript" type="text/javascript"&
var oEditor = FCKeditorAPI.GetInstance('info_demo') ;
var str = oEditor.GetXHTML();
_demo.value=
我从数据库里取得一个"info_demo"值,如何能把它返回到页面上?我曾把取到的值写到下面"X"的地方,但是显示出来的都是html代码,我想可能这个方法不对.&FCK:editor id="info_demo" basePath="../fckeditor/" width="100%" height="500" toolbarSet = "Default" && X&&&&&&& &/FCK:editor&这个问题如何解决?修正:
String con = (String) request.getAttribute("content");
&td colspan="5"&
&textarea id="content" name="content" style="WIDTH: 100%; HEIGHT: 400px"&&%=con%&
&/textarea&
&script type="text/javascript"&
var oFCKeditor = new FCKeditor('content') ;
oFCKeditor.BasePath = "../../fckeditor/" ;
oFCKeditor.Height = 500;
oFCKeditor.ToolbarSet = "Default";
oFCKeditor.ReplaceTextarea();
&/script&&/td&

&script type="text/javascript" src="../../fckeditor/fckeditor.js"&&/script&
&td colspan="5"&&textarea id="content" name="content" style="WIDTH: 100%;
HEIGHT: 400px"&&/textarea&
&script type="text/javascript"&
var oFCKeditor = new FCKeditor('content') ;
oFCKeditor.BasePath = "../../fckeditor/" ;
oFCKeditor.Height = 500;
oFCKeditor.ToolbarSet = "Default";
oFCKeditor.ReplaceTextarea();

一般大家都是使用json-lib来解析出来json类的，jso ...
JSONObject json= new JSONObje ...
