<请教>直接使用Ajax来拼接html页面，这样的做法有什么优劣，可行么？

例如：

 $.ajax({
            url:"http://"+host+"/cicro/notice_front/load_page.do",
            type:"post",
            data:{"page":0},
            dataType:"json",
            async:false,
            success:function(result){
            $('#news_box').empty();
            $('#news_box').append('<div class="news comWidth"><div class="news_top"><div class="news_top_top"><img class="news_top_left fl" src="../images/main_titles2.jpg" width="360" height="75"><p class="news_top_right fr"><img src="../images/hzhb04.png">当前位置：<a href="../cicro_fore/index.html">首页</a><img src="../images/hzhb04.png">通知公告</p></div></div><!-- 公告列表 --><div class="news_list" id="news_list"></div><div id="pageGro" class="cb"></div></div>');
            var count = 1;
            for(i = 0; i < result.data.length; i++){
                var s = result.data[i];
                var content = s.content;
                var title = s.title;
                var createtime = s.createtime.substring(0, 19);
                var p=s.state;
                if(p==1){
                    var str="未发布"
                }else{
                    str="已发布";
                }
                $('.news_list').append('<a href="javascript:go('+s.id+');" class="title"><div class="news_content"><img src="../images/hzhb04.png">'
