这个警告该怎么解决?是要修改video里的key吗？

Question

[WDS] Warnings while compiling.
./node_modules/vue-loader/lib/template-compiler?{"id":"data-v-45eba5d4","hasScoped":true,"transformToRequire":{"video":["src","poster"],"source":"src","img":"src","image":"xlink:href"},"buble":{"transforms":{}}}!./node_modules/vue-loader/lib/selector.js?type=template&index=0!./src/components/RotationChart_gzh.vue
(Emitted value instead of an instance of Error) Do not use v-for index as key on <transition-group> children, this is the same as not using keys.

Answer 1

这里是提示你v-for时不要:key="index"，而是用其他唯一的值，如每一项的id，:key="item.id"

Answer 2

在imgList加标识，已解决
