Excuse me, how should I operate?

It’s usually best to use key with v-if + v-else, if they are the same element type (e.g. both <div> elements).

By default, Vue updates the DOM as efficiently as possible. That means when switching between elements of the same type, it simply patches the existing element, rather than removing it and adding a new one in its place. This can have unintended consequences if these elements should not actually be considered the same.

Good

<div
  v-if="error"
  key="search-status"
>
  Error: {{ error }}
</div>
<div
  v-else
  key="search-results"
>
  {{ results }}
</div>

Bad

<div v-if="error">
  Error: {{ error }}
</div>
<div v-else>
  {{ results }}
</div>
