layui-弹出层中关闭自身层窗口

目的：单击地图标注点，ajsx查询无数据弹出无数据并关闭当前弹出层
重点：js用到layer.close(layer.index); //layer.index最新弹出层

marker.addEventListener('click', function () {
    
    
   $.ajax({
    
    
                                type:"post",

                                data:{
    
    "action":"room","corpid":index,"roomid":corpdata.list[index].id},
