<ul>
<template v-for="item in items">
<li>{{ item.msg }}</li>
<li class="divider" role="presentation"></li>
</template>
</ul>
like this
<ul>
<template v-for="item in items">
<li :key="item.id+1">{{ item.msg }}</li>
<li :key="item.id+2" class="divider" role="presentation"></li>
</template>
</ul>key is to distinguish elements and cannot be placed on template. The values of key can be spliced according to the requirements, so use
flexibly.<template v-for="item in items">
<li :key="item.id + '-1'">{{ item.msg }}</li>
<li :key="item.id + '-2'" class="divider" role="presentation"></li>
</template></li>
