[微信小程序]这是什么情况！ [没情况的最大情况]
- 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

请把问题描述清楚。 你想要干嘛？ 出现了什么问题？ , 你了解我么
-
data: { arr:[], }, onLoad: function (options) { this.setData({"arr[0].id":0}) this.setData({"arr[1].id":1}) }, 得到的结果是 第一个和第二个元素的id都是1 , 说的貌似很有深意，你能一条一条说么？
-
建议setData能省着用就尽量省, 你想表达什么意思？
-
-
相当的复杂啊, 怎么复杂了
-
浅拷贝的数据拿不到, 此话怎讲？
-
let arr=this.data.arr; arr[0].id"=0; arr[1].id=1; this.setData({arr:arr}) 浅拷贝的数据拿不到 , 恩 接着说
-
问题已搞定，浅拷贝的问题。, 我读书少，不知道你在说什么。
