Sending a variable to a VueJS component

Sending a variable to a VueJS component

I'm looking to pass a variable down to a component in my current setup. Here's the structure:

Main: Meet.vue

<html>
 <div class="carousel-cell">
    <Category :searchTerm="woman"></Category>
    </div>
 <div class="carousel-cell">
    <Category :searchTerm="men"></Category>
    </div>
[..]
<script>
import Category from './Category'
export default {
  components: {
    Category
  },

Sub: Category.vue:

export default {
  data () {
    return {
      search: [what's the best way to retrieve the **searchTerm** value here?]

How can I access the searchTerm value

<Category :searchTerm="woman"></Category>

defined in Meet.vue within Category.vue?

javascript vue.js vuejs2 vue-component

Answer №1

To implement the searchTerm property in your Category component, follow the instructions provided in the VueJS Documentation

Inside Category.vue

export default {
  props: ['searchTerm'],

  // Include your component code here (computed, methods, watch, ...)
}

If you want to add validation to your prop

export default {
  props: {
    searchTerm: {
      type: String,
      required: false,
      // You can set a default value if not required
      default: "woman"
    },
  }

  // Include your component code here (computed, methods, watch, ...)
}

To access your prop, use this.searchTerm. You can also directly use it within

<template></template>

with {{ searchTerm }}, for instance.

If you need to modify the value of the prop at any point, it's recommended to assign it to a local variable first and then make changes

props: ['searchTerm'],
data: function () {
  return {
    // Assign prop value to local variable for modifications
    search: this.searchTerm
  }
}

When using the Category component, follow these steps:

<Category :search="woman"></Category>

In this context, :search:"woman" indicates that the value woman is being passed to the property of the Category component.

Within the Category component:

export default {
  props: {
    search: {type: string, required: true}
    //An error will occur if anything other than a string is passed to 'search'
    //An error will also occur if 'search' is not passed at all
  }
  //Other content here

or

export default {
  props: [search], //No data type checking and not mandatory
  //Other content here

Utilizing props in your code allows for a more organized structure. Here is an example:

export default{
    props: ['searchTerm'],

This makes it easier to access and manipulate the data.
