What is the best way to activate a click event in Vue.js?

Hey there! I'm facing a situation where I have a button within the child component that emits an event when clicked. Is there a way to trigger this event when the parent component is mounted? Alternatively, is there another method to achieve this goal? Just as a heads up, the button is generated using v-for in the child component.

Answer №1

Your child component could be structured as shown below:

<template>
  <div class="child">
    <button @click="buttonClick">Button</button>
  </div>
</template>

<script>
  export default {
    props: ['buttonId'],
    methods:{
      buttonClick() {
        this.$emit('buttonClick', this.buttonId)
      }
    }
  }
</script>

As for your parent component:

<template>
  <div class="parent">
    <child v-for="i in 5" :buttonId="i"></child>
  </div>
</template>

<script>
  import Child from './Child.vue'

  export default {
    components: {
      Child,
    },
    methods: {
      onButtonClick(buttonId) {
        console.log('Received a click event from button ', buttonId)
      }
    },
    mounted() {
      this.$children.forEach(child => {
        child.buttonClick()
      })
    }
  }
</script>
