JavaScript自动添加删除

Question

从 '{success: true,data: ["a,92","b,0","c,0","d,43","e,0","f,80","g,0","h,50","j,20","k,5"]}'中提取数字作为一行，页面只能显示8行内容，每增加一行需要删除上一行，再添加新一行，并且需要挂载上删除的动画，有没有大佬给个解决思路

Answer 1

let data = {success: true,data: ["a,92","b,0","c,0","d,43","e,0","f,80","g,0","h,50","j,20","k,5"]};

let col = data.data.map((v) => {

  return v.split(',')[1];

});

我觉得可以用二维数组存储

使用Array.shift()删除第一个数组

使用Array.unshift()添加新数组
