dropLoad.js移动端分页----Vue数据每次清空累加

dropLoad.js移动端使用

1、需要引入  dropload   必要的两个文件dropload.css 、dropload.min.js

此案例在vue项目中使用过程：

var vm = new Vue({
el:'#app',
    data:{
        page:1,   　　　　　 //当前页数
        dropload:null,　　　//dropload定义
　　　　 limit ：10，       //请求数据的条数

    },
    created: function () {

    },
    mounted:function(){
    },
    methods:{
　　　　　//请求分页数据后在排序，会造成与上次分页出展示数据不一致，这里实现数据累计limt请求数据为总显示数据条数
        limitFn(){
            var self = this;
            var totalNum = self.datainfoList.length;
            self.limit = totalNum;
        },
        dealerSelectFn:function(){
            var self = this;
            self.dealer_id = dealer_id;
            methods.ajax("/index.php/Specialcar/SpecialInfo/specialList",{
                page:self.page,
                limit:self.limit,
            },function(res){
　　　　　　　　//res.data.list 为要展示的数据列表
                if(res.data.list.length>0){
　　　　　　　　　　　　//每次请求出的新数据与上次数据进行累计,concat

                    self.datainfoList=self.datainfoList.concat(res.data.list);
                }
　　　　　　　　//分页请求的最后一次数据为空，所有length为0时提示 “没有更多信息了”

                if(self.page>1 && res.data.list.length==0){
                    methods.prompt("没有更多信息了！")
                    return false;
                };
                //分页code
                self.setOrderList(self.datainfoList)
            })
        },
        setOrderList(data){
            var self = this;
            if(self.dropload){
                self.dropload.resetload();
            }else{
                //分页   ------   加载更多
                self.dropload=$('.order-list').dropload({
                    scrollArea : window,
                    autoLoad:false,
                    loadDownFn : function(me){
                        self.page++;
                        self.dealerSelectFn();
                    }
                })
            }
        },
    },
    filters: {

    }
});
