Can someone provide guidance on utilizing the index correctly within this v-for to prevent any potential errors?

I am encountering an issue with using index in a v-for loop to implement a function that deletes items from an array. The linter is flagging "index is defined but never used" as an error.

I am following the instructions provided in a tutorial, but I am unsure of the correct placement for the index variable.

<template>
    <div class="row">
        <app-quote v-for="(quote,index) in quotes" :key="quote.id" @click.native="deleteQuote(index)">{{ quote }}</app-quote>

    </div>
</template>

<script>
import Quote from './Quote.vue';

export default {
    props: ['quotes'],
    components: {
        appQuote: Quote
    },
    methods: {
        deleteQuote(index) {
            this.$emit('quoteDeleted', index);
        }
    },
}
</script>

Answer №1

If you want to remove a specific quote, you can directly pass the index to the deleteQuote function:

<app-quote v-for="(quote, index) in quotes" :key="quote.id" @click.native="deleteQuote(index)">{{ quote }}</app-quote>

Typically, you can choose to ignore eslint warnings for a single line of code:

<!-- eslint-disable-next-line -->

However, in this scenario, there is no need to do so.
