The problem arises when Transition's hook is destroyed and then reactivated

Question

The problem arises when Transition's hook is destroyed and then reactivated

My code includes a parent and child component, with the child component containing a <transition> element with specific options:

<template lang="pug">
  div
    transition(name="fade-transition" mode="out-in" v-on:after-enter="fnAfterEnter")
      h1(v-if"someCondition") lorem ipsum
</template>

<script>
  export default {
    methods: {
      fnAfterEnter () {
        do something here...
      }
    }
  }
</script>

The issue arises in the parent component where some functions are used to mount and destroy the child component based on a simple v-if condition. Although everything works correctly upon the initial mounting of the child component, subsequent cycles of destroying and remounting result in none of the hooks within the <transition> element triggering the fnAfterEnter method.

I appreciate any assistance you can provide :)

Answer №1

After troubleshooting, I discovered that the issue stemmed from the child component's transition not being fully completed. In my parent component, I was invoking a function to set the child component's transition item condition to true without utilizing $nextTick. To resolve this issue, I made the following adjustments in the code snippet below:

<script>
  export default {
    methods: {
      someFnInParent () {
        this.$nextTick(() => {
          this.$refs.childComp.someCondition = true
        })
      }
    }
  }
</script>

Implementing this.$nextTick(() => {}) successfully resolved the problem.
