Slots are a powerful feature in Vue.js that allow you to create dynamic and reusable components. They provide a way to pass content from a parent component to a child component, giving you the flexibility to customize the appearance and behavior of your components based on specific use cases.
Vue.js provides two main types of slots:
tag.
tag.To create a slot in a child component, you can use the
tag:
This code defines a default slot that will render the content passed to the slot from the parent component.
To pass content to a slot from a parent component, you can use the
syntax:
This is the content being passed to the slot
This code passes the content "This is the content being passed to the slot" to the default slot of the my-component
.
To create a named slot in a child component, you can use the
tag:
This code defines two named slots, "header" and "body", within the child component.
To pass content to a named slot from a parent component, you can use the
syntax:
This is the header content
This is the body content
This code passes the content "This is the header content" to the "header" slot and the content "This is the body content" to the "body" slot of the my-component
.
Scoped slots are a special type of slot that allows you to pass data and methods from a parent component to a child component along with the slot content. This enables you to create more dynamic and interactive components.
To create a scoped slot in a child component, you can use the syntax:
{{ title }}
This code defines a scoped slot named "header" that renders an tag with the
title
data passed from the parent component and a button that triggers the handleClick
method.
To pass data and methods to a scoped slot from a parent component, you can use the
syntax:
This code passes the title
data and the handleClick
method to the "header" scoped slot of the my-component
.
A common use case for slots is creating reusable card components that can display different content based on the context. You can define a
component with a default slot and then use it to display various data or content within the
:
Using this component, you can create cards with different titles and bodies:
Card 1
This is the body of Card 1
Card 2
This is the body of Card 2
Slots enable you to create reusable components that can easily be customized with different content, making your code more organized and maintainable.
Another use case for slots is dynamically populating a navigation menu based on user roles or permissions. By using named slots, you can create a
component that displays different menu items depending on the user's privileges:
From the parent component, you can then pass the appropriate menu items to the
component based on the user's role:
Admin Dashboard
Admin Settings
User Profile
User Orders
Slots facilitate the creation of dynamic and interactive components that can adapt to different scenarios and user roles.
Finally, slots can be used to create forms with dynamic fields that can be added or removed based on user input. You can define a
component with a default slot and a v-model
to receive the user's input:
Then, from the parent component, you can use the
component to dynamically add or remove fields to the form:
Slots offer flexibility and data binding capabilities, empowering you to create complex and user-friendly forms that adapt to changing requirements.
