it is certainly not possible for all your loops to be judged by the same index . index is the number of 1 times N , which is bound to be repeated.
your code can be identified directly with the values of the array
<span
v-for="(j, index2) in i.data"
:key="j"
:class="{'active': tabIndex == j}"
@click="select(j)">
{{ j }}
</span> of course, it's possible to use index if the cache objects of each loop are different, but the multi-selection effect may not be the
add multi-key cache to your code
pass in letter, and use letter to make a judgment
