选项卡 + 下拉加载 ，动态数据，如果初始化自动触发下拉刷新

loadcontent() 方法是获取初始化数据的，但是如果初始化没有数据，选项卡会一直提示 “正在加载中...”如图

window.onload = function(){  
                vm = new Vue({  
                el : 'body',

                });  
                loadcontent();  
            };  

            function loadcontent(){  
                var userid = localStorage.getItem("userid");   
                var params = {  
                        userid : userid  
                    }
