Creating pagination component - vue.js

Question

I am trying to create pagination component. For e.g if my API returns "pages": 9
For example, if I have 9 pages, I want to cut the list at 5 and add three dots like on the image. I want to be able to provide at which index I can cut the list. Whats the best way to do this? I am approaching this wrong?
<div v-for="index in pages" class="flex">
<button>{{index}}</button>
</div>

Answer 1

Assuming you receive cutIndex and apiPages as props to your component, then your template could look something like the following:
<div v-for="page in Math.min(cutIndex, apiPages)" class="flex">
<button>{{page}}</button>
</div>
<template v-if="cutIndex < apiPages">
<div class="flex">
<button>...</button>
</div>
<div class="flex">
<button>{{apiPages}}</button>
</div>
</template>

Answer 2

this code works for me, and here is the key part
<template>
...
<template v-for="index in pages"
v-if="(index < 4 || (length - index) < 3) || Math.abs(index - value) < 2">
<span v-if="index === (length - 2) && value < (length - 4)">
...
</span>
<button #click.prevent="updatePage(index)">
{{ index }}
</button>
<span v-if="(index === 3 && value > 5)">
...
</span>
</template>
...
</template>
the result:
<template>
<nav class="flex items-center justify-center" role="pagination">
<!-- go to previous page -->
<a :key="`${$route.name}-arrow-${value > 1 ? value - 1 : 1}`"
:href="getFullPath(value > 1 ? value - 1 : 1)"
:title="$t('previous_page')"
#click.prevent="updatePage(value > 1 ? value - 1 : 1)"
:disabled="value === 1"
class="arrow pop-btn default rounded-sm"
v-waves>
<i class="mdi-chevron-left mdi"></i>
</a>
<template v-for="index in length"
v-if="(index < 4 || (length - index) < 3) || Math.abs(index - value) < 2">
<span v-if="index === (length - 2) && value < (length - 4)">
...
</span>
<a :href="getFullPath(index)"
:title="$t('page_index', {index: index})"
#click.prevent="updatePage(index)"
class="pop-btn number default rounded-sm"
:class="{
'active': index === value
}"
v-waves>
{{ index }}
</a>
<span v-if="(index === 3 && value > 5)">
...
</span>
</template>
<!-- go to next page -->
<a :href="getFullPath(value === length ? value : value + 1)"
:title="$t('next_page')"
#click.prevent="updatePage(value === length ? value : value + 1)"
:disabled="value === length"
class="arrow pop-btn default rounded-sm"
v-waves>
<i class="mdi-chevron-right mdi"></i>
</a>
</nav>
</template>
<script type="text/javascript">
export default{
emits: ['update:value],
props: {
length: {
required: true,
type: Number
},
// the page filter
value: {
required: true,
type: Number
}
},
methods: {
updatePage(index){
this.$emit('update:value', index);
},
getFullPath(page){
let query = {...this.$route.query};
page === 1 ? delete query.page : query.page = page;
return this.$router.resolve(
this.r({
query: query,
name: this.$route.name,
params: this.$route.params
})
).href;
}
}
}
</script>
by the way, <a> may better than <button> for SEO
