Uncaught TypeError: Cannot read property 'addEventListener' of null

[ruanhaojian]

The error comes from :

setTimeout(() => {
  this.scrollHandler();
  this.scrollParent.addEventListener('scroll', this.scrollHandler, evt3rdArg);
}, 1);

when i use v-if direactive on this component, for example :

<infinite-loading
  v-if="isShow"
/>
