ajax 使用jquery处理返回的xml

 

public String buildTree() throws Exception{
		 List<TwiooDictionary> list = dictionaryManager.findTwiooDictionaryList();
		 StringBuffer buf = new StringBuffer();
		 buf.append("<root>");
		 for(TwiooDictionary td : list){
			buf.append("<item>");
			buf.append("<id>" + td.getId() + "</id>");
			buf.append("<name>" + td.getName() + "</name>");
			buf.append("<pid>" + td.getParentId() + "</pid>");
			buf.append("</item>");
		 }
		 buf.append("</root>");
		 
		 callbackClient(this.getResponse(),buf.toString());
		return null;
	}
private void callbackClient(HttpServletResponse response,String js)throws IOException{
		try{
			response.setContentType("text/xml;charset=UTF-8");
		    response.setHeader("Cache-Control", "on-cache");
			java.io.PrintWriter write  = response.getWriter();
			write.write(js);
			write.close();
		}catch(Exception e){
			e.printStackTrace();
		}
		
	}

 上面得注意

response.setContentType("text/xml;charset=UTF-8");
与
response.setContentType("text/html;charset=UTF-8");
是不一样的，如果写成html下面  $(data).find('item').each(function()  
可能 取不了值

<script type="text/javascript">
    	
		$(document).ready(function(){
			$.ajax({
		    	type: "GET",
		    	url: "buildTreeDictionary.action",
		    	success: function(data){
		    		d = new dTree('d');
					d.config.target = "mainFrame2";
				   	$(data).find('item').each(function(){                       
          				var name = $(this).find('name').text();
          				var id = $(this).find('id').text();
          				var pid = $(this).find('pid').text();
          				d.add(id,pid,name,'editNodeDictionary.action?nodeId='+id);
          			});
          			//alert("============="+d);
          			// alert(d.toString());
          			
          			$("#dtree2").html(d.toString());
				}
			});
		 });
	</script>
