举个例子后台这样拼接 rn [WebMethod]rn public static string temp()rn rnrn string content = "\"name\":\"ly\",\"pwd\":\"123\"";rn return content;rn rn前台这样接收rn $.ajax(rn //要用post方式 rn type: "Post",rn //方法所在页面和方法名 rn url: "zzjz_HomePage.aspx/temp",rn contentType: "application/<em>json</em>; charset=utf-8",rn dataType: "<em>json</em>",rn success: function (data) rn //返回的数据用data.d获取内容 rn alert(data);rn alert(data.d);rn alert(data.d.pwd);rn ,rn error: function (err) rn alert("未知错误");rn rn );rndata:[object Object]rndata.d:"name":"ly","pwd":"123"rndata.d.pwd:undefinedrndata.d.pwd不应该就是123么?

SSH2 jquery JSON 取值问题
问题直说,这个是struts2 配置文件rn[code=XML] rn rn rn rn [/code]rn这个是action 代码:rn[code=Java]@Controller rnpublic class ZfxxAction extends ActionSupport rn @Resource IZfxxBiz zfxxBiz;rn private List list;rn rn public List getList() rn return list;rn rnrn public void setList(List list) rn this.list = list;rn rnrn public String execute()rn list = zfxxBiz.findAll();rn return "list";rn rn[/code]rn最后这个是JS代码:rn[code=JScript]$(function() rn $.ajax( rn url : "zfxx!execute.action",rn type : "POST",rn dataType : "<em>json</em>",rn beforeSend : function() rn // $("#zfxx").html("error!");rn //alert("waitting!")rn ,rn success : function(data) rn alert(data);rn rn ); rn)[/code]rnrnrnrn问题就是 取不到值,而且action设断点也没进去。JSON架包已经添加。部署没问题,搞不懂为什么,请教前辈们帮忙。

从list取值
主要是实现功能:在jsp页面输入SQL语句,下面显示结果。基本思路:SQL语句存入hashmap,然后hashmap存入list,从list怎么取hashmap?从hashmap怎么取结果?用jsp取,相关代码:rnpublic static List executeQueryStringList(String sql) rnrn if (sql == null || sql.trim().equals("")) rn log.info("参数sql不能为空,必须是select语句。");rn throw new NullPointerException("sql参数不能为空字符串或者null。");rn rn Connection conn = null;rn PreparedStatement pst = null;rn ResultSet rst = null;rn List l = new ArrayList();rn try rn conn = DbConnection.getConn(); // 打开链接rn pst = conn.prepareStatement(sql);// 开始执行sqlrnrn ResultSetMetaData rsmd = pst.getMetaData();rn int columnCount = rsmd.getColumnCount();// 获取所有的列数;rn String[] columnStr = new String[columnCount];rn for (int i = 1; i < columnCount; i++) rn tempObject[i] = rst.getObject(columnStr[i]) == null ? ""rn : rst.getObject(columnStr[i]).toString(); // 如果key和value任意一个为null,均会抛出异常rn rn l.add(tempObject);rn rn if (l.size() < 1)rn l = null;rn catch (SQLException e) rn log.error(sql + "语句查询出错!", e);rn return null;rn finally rn closeAll(rst, pst, conn);rn rn return l;rn rnn[b]问题补充:[/b]n代码是领导给的,让我直接从list调出hashmap,然后从hashmap<em>取值</em>,我对于集合类不了解,这方面知识欠缺,怎么写jsp代码,从list调出hashmap呢?
