How can I access a v-model that is located in a different component? The search field is within the App.vue file and I am trying to activate the :search='search' property in the Datatable.vue component.
Code in App.vue:
<v-text-field
v-model="search"
class="mx-3"
label="Search"
></v-text-field>
Code in Datatable.vue:
<v-data-table
ref='dTable'
:items='products'
:search='search'
class='elevation-1'
>
There are several methods available to facilitate data sharing between components.
In this scenario, with the v-text-field connected to your search data, you can easily transfer it to your Datatable component.
<div id="app">
<v-text-field v-model="search" ... />
<Datatable v-bind:search="search" ... />
</div>
Subsequently, you must retrieve and utilize it within your Datatable component.
An option is to establish a serviceBus that broadcasts changes throughout your application. Refer to this blog post for further details.
In your case, you would set up a listener for
serviceBus.$on('searchInitiated', (query) => { ... })serviceBus.$emit('searchInitiated', this.search)This approach enables the sharing of component state across distinct components without being restricted by hierarchy.
Another approach involves allowing a "parent component" to manage your state and then transmitting the data to child components.
This method may become cumbersome if dealing with a complex component structure, as the prop needs to be passed from one component to another.
You also have the ability to dispatch values from a child component (Search) to the parent component (App), and subsequently share this information with your DataTable.
Similar to the "Service bus" example, the difference lies in not having a "shared bus" - instead, requiring the attachment of the callback specifically to your child component.
