问题描述

項目需要添加點贊與評論功能 目前點讚頁面顯示 是正常的 但是點贊過後需要添加點讚人姓名 我是卡在這個地方 setData便利 從全局到局部 都試過 目前局部刷新 前十個能實現
後面失敗 找了下錯誤 原來每次下拉加載的時候 會把list下標改回程0-9 這個是java後台
我這樣後台不好改 我這邊也不好做 有沒有什麼解決方案？可以給點思路

问题出现的环境背景及自己尝试过哪些方法

用过局部刷新

        var param = {};
        var string = "DiggArray[" + index + "]"
        param[string] = res.data.list[index].likeList
        _this.setData(param);

只能更改前十 后台返回pageNum：2 后 下标更新为另外一个0-9

你期待的结果是什么？实际看到的错误信息又是什么？

希望能有大佬跟我说下 在后台返回会刷新下标的情况下 我该如何判断新数组的下标
