报错情况
报错原因
迭代中的[vue/require-v-for-key]元素希望有“v-bind:key”指令
解决办法
在后面加上 :key = "item.index"
2、如果报错Expected ‘v-bind:key’ directive to use the variables which are defined by the ‘v-for’ directive.
报错原因
应使用“v-bind:key”指令来使用“v-for”指令定义的变量。
解决办法
错误写法
javascript"><div v-for="ITEM in videoList" :key="index">
正确写法
javascript"><div v-for="ITEM in videoList" :key="item.index">
