前端通过ajax解析字符串

后台：

String sear = request.getParameter("sear");//验证用户表中是否存在SearchDao searDao  = new SearchDao();List<String> lst = searDao.query(sear);//返回ajax响应StringBuffer sbf = new StringBuffer();for (String str : lst){sbf.append(str+",");}String result = "";if (lst.size()>0){result = sbf.substring(0, sbf.length()-1);}response.setCharacterEncoding("UTF-8");response.setContentType("text/html");PrintWriter out = response.getWriter();out.write(result);out.flush();out.close();

后台将数据转化成一定格式的字符串；

前端：

$.get("user?method=checkUsername",{"sear":sear},function(result){if(result != " "){var arr = result.split(",");for (var i=0;i<arr.length;i++){$("#mydiv").append("<div class='sb'>"+arr[i]+"</div>");}                                 }                               });

前端将字符串拆开，然后再显示；
