vuejs实现本地数据的筛选分页功能思路详解

var subList=new Vue({
  el:'#main',
  data:{
    // subcontentData为本地数据
    subContents:subcontentData,
    // 页面需要展现的数据
    yemiandata:[],
    // 页面展现条数
    datanum:12,
    // 开始椰树
    startnum:0,
    // 结束椰树
    endnum:1,
    // 一共多少页
    btnnum:0,
    // 生成切换页面的按钮用
    listnum:[],
    // input跳转
    jemp:1,
  },
  methods:{
    filters(num){
      this.subContents=subcontentData;
      // 需要重置防止翻页导致startnum和endnum不一致
      this.startnum=0;
      this.endnum=1;
      // 这里是判断筛选按钮
      switch(num){
        case 0: $('#sublist li').css({
