本实例是根据工作进度的百分比来进行排序。

   <div class="ibox-content">
         <li v-for="(rangeItem,index) in range" :key="index" class="rankLi">
           <span class="rankSpan">{{index+1}}</span>

export default {

        { name: "TP006", percent: "35" },
        { name: "TP007", percent: "49" },
        { name: "TP008", percent: "46" }
      ]
    };
  },
  computed: {
    range: function() {
     // return this.rangeList.sort((a,b)=>a.percent<b.percent);//降序,此方法在数据量多的时候会乱序，不明其理

return this. rangeList. sort(( a, b) => a. percent - b. percent). reverse()//结合reverse(),成功实现降序排列

  computed: {
    range: function() {
      return this.rangeList.sort((a,b)=>a.percent-b.percent);//升序
    }
  }
