Tips for retrieving data from a child component within a parent component in VueJs

In my Vue Application, I have various child components that are dynamically loaded based on the values selected in the parent component. When the submit button in the parent component is clicked, I need to retrieve all the values from the child components and pass them to the parent.

<template>
<div>

<v-select v-model="category"/>


<firstComponent v-show="category == 1">
<secondComponent v-show="category == 2">

<v-btn @click="submitData">Submit</v-btn>
</div></template>

Ignore the syntax, but essentially I'm looking for a way to gather input field data from the child components and include it in the submitData method of the parent component.

When working with VueJS, accessing children components via the component id can be challenging. Instead of using this method, consider the following options: 1. EventBus: While it allows communication between components, it can become difficult to trace where events need to be listened for and called, especially in projects with a large number of files. Read more about EventBus here. 2. Vuex: This solution is more suitable for VueJS web development purposes.

If you want to pass data between components, scoped slots can be a useful option. For example, within the firstComponent, you can do something like this:

<slot :data="sharedData">
// Additional content can go here but it's not necessary
</slot>
// In parent component
<firstComponent>
 <template v-slot="{sharedData}">
....

By utilizing shared data through scoped slots, you can easily pass it along to your submit function.

Vue offers several methods for data sharing, such as serverbus, Vuex, and event emitting in child-parent relationships.

In your specific scenario, I recommend creating an object or array in the parent component to pass down as a prop to all child components. Then, bind the form values to the keys in the object. This way, any changes made will be reflected in the parent component due to the reference passing of arrays/objects. Alternatively, if you're comfortable with Vuex, that is also a good option.

Additionally, consider using dynamic components when rendering based on different categories to avoid cluttering your code with multiple v-show or v-if statements as the number of components grows. (https://v2.vuejs.org/v2/guide/components-dynamic-async.html)
