ssh和springside 實作ajax傳回對象清單

ajaxPage 整個是關鍵

struts_product.xml配置檔案，這個也是重點

ProductAction 頁面互動時候set，get不能少，（是頁面的給set和得到get）

public class ProductAction extends ActionSupport {
	private Integer productid;
	private ProductService ps;


	private int pageNow;
	private int pageSize;

原始的ajax互動可使用springSide action的

public void list1() throws Exception { // 資料的詳細清單
		map = new HashMap();
		map.put("jclg", "2ben");
		map.put("hbdx", "1ben");
		map.put("zkr", "dgs");
		/*
		 * set=map.entrySet(); Iterator it=set.iterator(); while(it.hasNext()){
		 * entry1=(Map.Entry)it.next(); }
		 */
		list = new ArrayList();
		list.add("123");
		list.add("456");
		/*
		 * if(account.equals("sun")){ msg="對不起賬号已經存在"; }else{ msg=""; }
		 */
		// struts裡面調用servlet api
		/*
		 * ServletActionContext.getResponse().setCharacterEncoding("utf-8"); //
		 * 把組裝好的html代碼回傳給ajax PrintWriter out
		 * =ServletActionContext.getResponse().getWriter(); out.println(msg);
		 */
		List<House> houseList = houseEntityManager.getHouse();
		ServletActionContext.getResponse().setCharacterEncoding("utf-8");
		PrintWriter out = ServletActionContext.getResponse().getWriter();
		out.println(JSONArray.fromObject(houseList).toString());
	}

var resultValue=$.ajax({
				 async: false,
				 type: "POST",
				 url: "sys-notebook!getNotebookDay.action",
				 data: "sYear="+sYear+"&sMonth="+sMonth,
				 success : function(data){//json對象
				 }
			}).responseText;
		   resultValueObj=eval("("+resultValue+")");

$.ajax({

url:'',

data:{

param1:'',

param2:''

}

});

var resultJson =

[
