Developing effective communication between parent and child components in VueJS v-data-table.Let

Currently facing a challenge and seeking assistance: I have two Vuetify "v-data-tables" 1 - Parent table 2 - Children's table (which is actually a reusable component)

I am in search of a universal code snippet that I can tweak for my project, where every time I click on a row in the Parent table, the Child table will display corresponding details based on ID

I have browsed online for examples but haven't been able to customize them to fit my application. Here is an example link: enter link description here

<template>
   <div id="app">
       <table-component :data="fetchData">
           <table-column show="firstName" label="First name"></table-column>
       </table-component>
   </div>
</template>

<script>
    import axios from 'axios';

    export default {
        methods: {
            async fetchData({ page, filter, sort }) {
                const response = await axios.get('/my-endpoint', { page });

                // An object that has a `data` and an optional `pagination` property
                return response;
            }
        }
    }
</script>

Answer №1

I came across a solution to my issue and thought it would be beneficial to share it with you. Firstly, I utilized the "Event bus" approach which can be found in numerous tutorials and instructional videos. 1 - I created a JS file named bus.js with the following code:

import Vue from 'vue'
export const EventBus = new Vue()

2- Within the Parent component's Methods:

EventBus.$emit('id', id)

"Id" serves as the identifier for the selected ROW.

3- In the second Child component that contains the details:

EventBus.$on('id', id => {
      console.log(id)
      this.idSelect = id
      console.log('Mounted' + this.idSelect)
      this.loadContenu()
    })

loadContenu is the method responsible for fetching detailed data from the API. idSelect is a variable that receives the ID sent from the Parent component.

There you have it! I wanted to share this valuable experience with you all in hopes that it may prove helpful.

Here is an example demonstrating how to pass props between parent and child components:

Parent Component:

<template>
    <div>
        <div @click="passId('12345')">
        </div>
        <childComponent 
        :theId = theId
        />
    </div>
</template>
<script>
import childComponent from 'path/to/your/childComponent'
export default {

    components:{
        childComponent 
    },
    data(){
        return{
            theId:null
        }
    },
    methods:{
    passId(id){
        this.theId = id    
    }
    }  
}
</script>

Child Component:

<template>
    <div>
        <div v-if="theId">
            <!-- do something with theID here -->
        </div>
    </div> 
</template>
<script>
export default {

    props:{
        theId:{
            type: String,
            default:null
        }
    } 
}
</script>
