JSON简单应用
今天做一个小功能，用ajax来提取数据列表，这里需要用到json。

后台把数组用Zend_Json::encode($value)处理下（ZF框架）或者json_encode()也可以。

前端用JS的for in把数组循环，前端web代码一起拼装放到一个字符串变量里，最后innerHTML
后台代码：

function liulanrecordAction(){            // 记录最近浏览            $current_goods_id = $this->_request->getParam('current_goods_id');            $browse_history = $this->getGoodsBrowseHistory($current_goods_id,Seed_Cookie::getCookie('browse_history'));            $expiretime = time() + 30*24*60*60;            Seed_Cookie::setCookie('browse_history',$browse_history,$expiretime,$this->view->seed_Setting['cookie_path'],$this->view->seed_Setting['cookie_host']);            //------------------------最近浏览过的商品------------------------            $my_browse = $this->_MyBrowse($browse_history);            $json_my_browse = Zend_Json::encode($my_browse);            //$json_my_browse = json_encode($my_browse);            echo $json_my_browse;            exit;        }

 $.get("<?php echo $this->baseUrl().'/index/liulanrecord';?>", {current_goods_id: "<?php echo $this->goods['goods_id']?>" },      function(data){          var key;          var htm_str = '';          for (key in data){              htm_str += "<div>";              htm_str += "<p><a href="+data[key]['url']+" target='_blank'><img src="+data[key]['original_img']+" /></a></p>";              htm_str += "<p class='fred'><b>￥"+data[key]['shop_price']+"</b></p>";              htm_str += "</div>";          }          document.getElementById('liulan').innerHTML = htm_str;      },'json');
