The effect is as follows

1. Set in the head

position: fixed; z-index: 999; top: 0; opacity:1;

Copy after login

2.ajax processing json Data

// 获取商城公告 function getNotice() { // 获取公告函数 var res; $.ajax({ type: "POST", url: "{sh::U('Store/Mall/ajaxGetNotice',array('mid'=>$mid))}", dataType:'json', // 设为json之后，就能够很好的处理获取的json数据，json.status async: false, success: function(json){ res = json; } }); return res; }

After setting dataType:'json', json data can be processed directly through json.

" }); $(".top-notice").show(); $('#notice ul').html(""+html); $('#notice').unslider(); // 轮播 } });

// 获取公告 function ajaxGetNotice() { if (IS_AJAX) { $this->mid; // 获取有效的，且结束时间大于当前时间的，或者日期等于0的公告 $mallNoticeModel = M('Mall_notice'); $where['mall_id'] = $this->mid; $where['status'] = 1; $where['endtime'] = array(array('eq',0),array('gt',time()), 'or') ; //SELECT * from sh_mall_notice where mall_id = 9 and status = 1 and (endtime = 0 or endtime>1458354366); $notice = $mallNoticeModel->where($where)->order('sort desc')->select(); if (!empty($notice)) { $this->ajaxReturn(array('status'=>'1','info'=>$notice,'msg'=>"获取成功"),'JSON'); } else { $this->ajaxReturn(array('status'=>'2','info'=>$notice,'msg'=>"公告不存在"),'JSON'); } } }
