I have a scrollbar appearing on all my pages. The issue seems pretty similar to this one, but I did not have the problem when on version 0.17 (and earlier), but it started after being on v1.0.0, so that is odd. I have it both on Chrome and on Firefox. I can make the scrollbar disappear by unchecking body { min-height: 100vh } in Chrome dev, but I do not know how to unset this css value in my code. I tried body { min-height: unset } and body {min-height: auto} but the scrollbar remains. Here is a fiddle that shows the behavior.

After using @load for the scroll-element and adding a nextTick it seems to work as should. See this stackoverflow-issue .

I have multiple children and need to scroll to a certain child after loading the page. I can do so by setting a delay using setTimeout but I would prefer a better/ fail-proof solution. My current approach is to wait for all children to mount (and use nextTick) and thought it should be ready for the scroll, but apparently not. Alternatively I can wait for all images to be loaded (as QImg has a @load event), but that is really late, since manually I can already trigger a scroll while image boxes are already rendered but still loading. What is the best way to trigger at ‘the earliest possible moment’?

Point-panel (parent):

new Vue({
  el: '#q-app',
  template: `
      <div id="point-panel" class='map-overlay column scroll'>
            <small-cards @child-mounted='cardsAreReady' 
                 v-for='(point, cardIndex) in picArray'
                 :key="cardIndex"
                 :point-object="point"
                 :card-index="cardIndex"></small-cards>
            <q-btn @click.native="scrollToCenter"
           fab
           ripple
           class='fixed'
           size="10px"
           color="black"
           label="scroll"
           style="right: 18px; bottom: 120px" />
  </div>
        </div>
    `,
  data() {
    return {
      parentMounted: false,
      selectedPointIndex: 6,      
      picArray: ["https://image1", "https://image2, "https://image_etc."]
     }
      },
      mounted: function() {
      let that = this
      	that.$nextTick( function(){
        	that.parentMounted = true
        })
      },
      methods: {
        notify(msg) {
          this.$q.notify(msg)
        },
        cardsAreReady(cardIndex) {
          console.log('one ready.......', `${cardIndex + 1} ...and total ${this.picArray.length}`)
          let that = this
          if (cardIndex + 1 === this.picArray.length) {
            console.log('....all cards MOUNTED!', cardIndex)
            setTimeout(() => {
              that.$nextTick(() => {
                console.log('..........trigger scroll NOW!')
                if (that.parentMounted === true) {
                  that.scrollToCenter()
                } else {
                  that.$q.notify('parent not yet ready!!')
                }
              })
            }, 0)
          }
        },
        scrollToCenter() {
          const that = this
          console.log('..........cardIndex: ', that.selectedPointIndex)
    
    
          function scrollFunction() {
            that.notify('scroll triggered!')
            const element = document.getElementsByClassName(
              that.selectedPointIndex.toString()
            )
            const target = document.getElementById('point-panel')
            const iW = window.innerWidth
            const iH = window.innerHeight
            const myOffset = element[0].offsetLeft
            Quasar.utils.scroll.setHorizontalScrollPosition(target, myOffset, 0)
    
          }
          setTimeout(() => scrollFunction(), 0)
        }
      }
    })
    

Images/ small-cards (children):

Vue.component('small-cards', {
  props: {
    pointObject: {
      type: Object,
      required: true
    },
    cardIndex: {
      type: Number,
      required: true,
      default: 0
    }
  },
  data() {
    return {
      selectedPointIndex: 6
    }
  },
  mounted: function() {
  let that = this
  that.$nextTick(function () {
   that.$emit('child-mounted', this.cardIndex)
   })
  },
  methods: {
    reportError(event) {
      console.log(`${event.name}: ${event.message}`);
    },
  },
  template: `
        <div class="mycard"
       :class="{'active': cardIndex === selectedPointIndex,
          [cardIndex]: true}">
    <q-img :src="pointObject"
           spinner-size="30px"
           style="background-color: rgba(255, 225, 215, 0.4)"
           @error="reportError">
    </q-img>
  </div>
  `
})

Here you can find a jsfiddle showing the issue. I have added a scroll button to show that after loading you can trigger a scroll successfully (the 6th picture, i.e. ‘the Tiger’ is scrolled to the bottom-left corner).

To give the question somewhat more direction: The problem is that if scroll is triggered to soon the Dom is not yet rendered and thus the distance to scrol can not yet be determined. But I would think that after mount in combination with $nextTick the Dom should be determined?! So why does current approach not work?

Yeah, I am on core-js 2 now and it works. Thanks!

Yeah for me too. Got some other errors now when running my app which I reported elsewhere.

I upgraded and the preset is included in my babel.config.js . When running dev script on my app I get:

I tried both npm and yarn, but both give same problems on a project that was working fine on v1 beta. After deleting node_modules and package-lock.json and reinstalling I get error saying all kinds of packages missing and suggesting to install them with:

But these seem core-js files so I am puzzled…?!

Exact same here.

@metalsadman Great! Thanks!

@metalsadman You’re right: mount should be function. However: in your version the picture the file.__img does not load either…, which was the point. The errors in the console are just showing up in codesandbox (for both the ‘one-component’ and ‘parent child’ solutions => should not matter) and are indeed related to quasar version (I found a related issue, which now is solved). I tried/ looked up using quasar v17 with codesandbox, but don’t know how to do it (you install the entire cli…?).
