Scroll Table to top when next table pagination is pressed



  • 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
          },
