- 当前 Bug 的表现（可附上截图）



- 预期表现
数组setData更新数据会覆盖前面元素

- 复现路径
setData

- 提供一个最简复现 Demo
setData内容{"listData[0]":{"id":0,"code":"pdtid","text":"产品编号：","type":"text","value":"","isdisplay":true},"listData[0].id":0,"listData[0].value":"w11111-1","listData[1]":{"id":0,"code":"pdtname","text":"产品名称：","type":"text","value":"","isdisplay":true},"listData[1].id":0,"listData[1].value":"产品1-1","listData[2]":{"id":0,"code":"anticode","text":"溯源码：","type":"number","value":"","isdisplay":false},"listData[2].id":0,"listData[3]":{"id":0,"code":"remark","text":"异常备注：","type":"text","value":"","isdisplay":false},"listData[3].id":0,"listData[4]":{"id":0,"code":"pdtid","text":"产品编号：","type":"text","value":"","isdisplay":true},"listData[4].id":1,"listData[4].value":"w11111-2","listData[5]":{"id":0,"code":"pdtname","text":"产品名称：","type":"text","value":"","isdisplay":true},"listData[5].id":1,"listData[5].value":"产品1-2","listData[6]":{"id":0,"code":"anticode","text":"溯源码：","type":"number","value":"","isdisplay":false},"listData[6].id":1,"listData[7]":{"id":0,"code":"remark","text":"异常备注：","type":"text","value":"","isdisplay":false},"listData[7].id":1}
