Utilizing a shared component in both a child and parent within a Vue application

Utilizing a shared component in both a child and parent within a Vue application

I am currently working on a VueJS project, where I have parent and child components within one view. Both components are using the same component called deleteModal.

The issue arises when I try to trigger the modal from the child component - it ends up triggering both the child and parent modals (even though no data is passed to the modal triggered by the parent). From my understanding, this happens because I have used the component twice in both parent and child components, as shown below. It's worth mentioning that everything functions as expected from the parent.

I have tried various solutions such as setting a unique key value for each of the components, changing the components' ref name, among other things. I also attempted using v-show to only display the component just before I trigger the parent modal, but this approach is not optimal.

Is there a way to only trigger the modal from the child component?

Parent Component

<template>
  <div>
    <childCompt ref="childCompt" />
    <deleteModal
      ref="deleteModal"
      @deleteTriggerAPI="deleteAPIParent"
    />
</div>
<template>

Child Component - childCompt

 <template>
      <div>
        <deleteModal
          ref="deleteModal"
          @deleteTriggerAPI="deleteAPIChild"
        />
    </div>
    <template>

My previous answer was not satisfactory. I prefer using jQuery to toggle elements in Vue. This method works best for me currently, although there may be better options available.

If you choose to only use Vue, you can pass variables from parent to child components to control the visibility of your modal.

We pass variables using ":", and register events using "@".

<template>
 <childComponent :isModalOpen="isModalOpen" @onModalClose="isModalOpen=false">
<template>
export default {
 name:"parent",
 data: () => {
  isModalOpen: false
 }
}

In the child component, we catch the passed variable using props. We need to specify the type of variable being passed. The main difference between props and data is that values cannot be changed in a child component through props.

export default {
 name: "child",
 props: {
  isModalOpen: Boolean
 }
}

You can then use this variable to show or hide the modal. Additionally, within the child component, we can create a button to close the modal and emit an event to the parent to update the variable value.

This is achieved by using this.$emit('eventName');

One potential solution is to define the component globally.

For example, in the main.js file:

Vue.component('deleteModal', deleteModal)
