Are you looking for a way to detect scrolling events on the v-data-table component in Vuetify framework?
I am referring to the scenario where the table has a fixed height, causing the table body to scroll.
<v-data-table
fixed-header
:height=400
:headers="headers"
:items="desserts"
item-key="name"
disable-pagination
hide-default-footer
></v-data-table>
To access the table DOM element after Vue has been mounted, simply refer to it using "this" keyword and proceed from there. Take a look at the mounted hook provided below for reference.
<template lang="html">
<div class="graph-content">
<v-data-table v-show="topArtistUplifts.length" id="topUpliftTable" class="data-table-custom"
:headers="tableHeaders" :items="topArtistUplifts" fixed-header :height="tableHeight"
:items-per-page="-1" hide-default-footer :mobile-breakpoint="0">
<template v-slot:item.artist_name="{ item }">
<span>
<router-link :to="{ name: 'Artist', query: { artistId: item.artist_id, ...linkQuery }}"
class="artist-link inline">
{{ item.artist_name }}
</router-link>
</span>
</template>
<template v-slot:item.absolute_number="{ item }">
<span>+{{ getAbbreviatedNum(item.absolute_number) }}</span>
</template>
<template v-slot:item.relative_number="{ item }">
<span :class="percentChangeStyle(item.relative_number * 100)">{{ percentChangeFormat((item.relative_number * 100).toFixed(2)) }}</span>
</template>
</v-data-table>
<div class="no-notifs full-height" v-show="!topArtistUplifts.length">

</div>
<Loader v-if="updating.topArtistUplifts" :height="50"/>
</div>
</template>
<script>
methods: {
handleUpliftScroll(e) {
console.log('yoooo i'm a table scroll event: ', e)
},
},
mounted() {
const tableWrapper = this.$el.children[0].children[0]
tableWrapper.addEventListener('scroll', this.handleUpliftScroll)
}
</script>
Check out this code snippet:
const app = new Vue({
el: '#app',
vuetify: new Vuetify(),
data() {
return {
desserts: Array.from({ length: 5000 }).map((v, k) => ({
name: `#${k}`,
calories: 518,
}),
headers: [
{ text: 'Dessert', value: 'name' },
{ text: 'Calories', value: 'calories' },
]
}
},
mounted() {
document.addEventListener('wheel', this.onScroll)
},
methods: {
onScroll() {
console.log('scrolling')
}
}
})
