Issue: I'm facing an issue with passing data from a clicked card to a modal component. The modal should display the title, image, preview URL, and download URL of the card that was clicked. However, I'm encountering an error that says
is not defined on the instance but referenced during renderIt seems like the data is not being passed into the modal even though I'm referencing the clicked card. I need a way to pass the index of the clicked card to the modal, but I'm not sure of the best approach to achieve this.
I'm currently using slots to handle the dynamic data from the v-for loop, and I hope I don't have to switch to props as it might complicate things.
Steps Taken:
<!-- Cards -->
<div class="card-wrapper">
<div v-for="(card, index) in cards" :key="index" class="card">
<div @click="showModal(card)" class="card-body">
<img :src="card.img" alt="resource img" />
<h4 class="card-title">{{ card.title }}</h4>
<h6 class="card-subtitle">{{ card.subtitle }}</h6>
</div>
</div>
</div>
<!-- MODAL -->
<Modal v-show="isModalVisible" @close="closeModal">
<template v-slot:header>{{ img }} </template>
<template v-slot:body>
{{ title }}
<div class="text-center mb-1 mt-2">
<a :href="previewUrl"><button class="modal-btn btn btn-large">Preview</button></a>
<a :href="downloadUrl"><button class="modal-btn btn btn-large">Download</button></a>
</div>
</template>
</Modal>DATA
`cards: [
{
title: "Card Title",
subtitle: "Card subtitle",
img: require("@/assets/images/test.jpg"),
previewUrl: "https://test.com",
downloadUrl: "https://test.com"
},`
METHODS:
`methods: {
showModal(card) {
this.isModalVisible = true;
this.title = card.title;
this.img = card.img;
this.previewUrl = card.previewUrl;
this.downloadUrl = card.downloadUrl;
this.isModalVisible = true;
},
closeModal() {
this.isModalVisible = false;
}
}`

export default {
