When div scrolled, call instance.update().

can you give me example of code for this one?

you can use :delay="-1" and vue-in-viewport-mixin to trigger instance.start().

I have same issue. Can you share any live example?

would appreciate live example as well

When div scrolled, call instance.update().

Hello, I was having problems of this type and finally I solved it as follows.

First add the scroll directive before your Vue instance:

Vue.directive ('scroll', {
  inserted: function (el, binding) {
    let f = function (evt) {
      if (binding.value (evt, el)) {
        window.removeEventListener ('scroll', f)
      }
    }
    window.addEventListener ('scroll', f)
  }
})

Then, where they place the component, they add the attribute ref = "firstcomponent" (change the name of the ref) and v-scroll = "onReady" (method that will update the counter) to each component that they want to "update" to the time to scroll.

Example:

<div class="iCountUp">
<ICountUp :delay="delay" :endVal="endVal" :options="options" ref="firstcomponent" v-scroll="onReady"/>
</div>

Finally, in the method, they can do an if of this type:

if (window.scrollY> 800) {
                this.$refs.firstcomponent.update(that.endVal + 100);
 }

By doing this, each time the scrollY is greater than 800, each component will be updated with the assigned value, in this case "100".

There is already a scroll spy in the countup.js library, but because instance.start() is always called, this option (enableScrollSpy) doesn't work with vue-countup-v2. PR needs to be made to only run .start() when enableScrollSpy is disabled
