Scroll Table to top when next table pagination is pressed

[thekingrenz23]

I have a lot of data to render on my table.

5k plus data. I limit it 50 records per page.

The problem is when the next pagination is pressed the scroll stays where you left it.

I want to scroll to the top again when i press the next pagination

Thanks

@thekingrenz23 you could watch the pagination object and use https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView

I’m on mobile now, but I’ll post an example in the morning if you don’t figure it out. I just did the same sort of thing last week.

For an example, it’s something like this. Quasar has some scrolling utils you can use instead of a raw scrollIntoView call: https://quasar.dev/quasar-utils/scrolling-utils#Scrolling-to-an-element

Also, you can watch all pagination props with a deep watcher instead of 'pagination.page': https://vuejs.org/v2/api/#watch

<template>
  <div id="myTable" class="q-pa-md">
    <q-table
      title="Treats"
      :data="data"
      :columns="columns"
      row-key="name"
      :pagination.sync="pagination"
    />
  </div>
</template>
<script>
export default {
  watch: {
    'pagination.page'() {
      document.getElementById('myTable').scrollIntoView()
    } 
  },
  data () {
    return {
      pagination: {
        sortBy: 'desc',
        descending: false,
        page: 2,
        rowsPerPage: 3
        // rowsNumber: xx if getting data from a server
      },

      columns: [
        {
          name: 'desc',
          required: true,
          label: 'Dessert (100g serving)',
          align: 'left',
          field: row => row.name,
          format: val => `${val}`,
          sortable: true
        },
        { name: 'calories', align: 'center', label: 'Calories', field: 'calories', sortable: true },
        { name: 'fat', label: 'Fat (g)', field: 'fat', sortable: true },
        { name: 'carbs', label: 'Carbs (g)', field: 'carbs' },

        { name: 'sodium', label: 'Sodium (mg)', field: 'sodium' },
        { name: 'calcium', label: 'Calcium (%)', field: 'calcium', sortable: true, sort: (a, b) => parseInt(a, 10) - parseInt(b, 10) },
        { name: 'iron', label: 'Iron (%)', field: 'iron', sortable: true, sort: (a, b) => parseInt(a, 10) - parseInt(b, 10) }
      ],
