]]>在项目中使用DWR框架需注意的http://www.blogjava.net/ITdavid/archive/2008/03/14/186202.html大卫大卫Fri, 14 Mar 2008 02:21:00 GMThttp://www.blogjava.net/ITdavid/archive/2008/03/14/186202.htmlhttp://www.blogjava.net/ITdavid/comments/186202.htmlhttp://www.blogjava.net/ITdavid/archive/2008/03/14/186202.html#Feedback1http://www.blogjava.net/ITdavid/comments/commentRss/186202.htmlhttp://www.blogjava.net/ITdavid/services/trackbacks/186202.html 在页面中添加：
1<script type='text/javascript' src='dwr/interface/Folder.js'>
2        </script>
3        <script type='text/javascript' src='dwr/engine.js'>
4        </script>
5        <script type='text/javascript' src='dwr/util.js'>
6        </script>
需要注意的是路径，而不是官方的：
1<script type='text/javascript' src='../interface/Folder.js'></script>
2  <script type='text/javascript' src='../engine.js'></script>
3  <script type='text/javascript' src='../util.js'></script>

二、返回的json串需要进行处理，才可以在前台javascript正确处理。
使用json-lib的JSONArray对List类型数据进行处理：
1JSONArray.fromObject(folders).toString();
返回List型的json数据为：
1[{"folderId":1,"folderName":"收信箱"},{"folderId":2,"folderName":"发信箱"},{"folderId":3,"folderName":"草稿箱"},{"folderId":4,"folderName":"回收站"},{"folderId":5,"folderName":"垃圾箱"}]
这个数据返回到前台一定要用Ext.util.JSON.decode(data)进行编码，否则javascript不能正常处理。
1//刷新文件夹列表，DWR获取数据。
2function initFolders(){
3    Folder.getFolderList(refrashFolders);}
4
5function refrashFolders(data){
6    folders = Ext.util.JSON.decode(data);//一定要用这个进行解码
7    initFolderTreeNode();}
