Slot props memungkinkan kita untuk mengubah slot menjadi templat yang dapat digunakan kembali, dan bisa di-render dengan konten yang berbeda, yang berbasis pada input props. Ini sangat berguna ketika Anda mendesain komponen yang dapat digunakan kembali yang merangkum logika data, yang memungkinkan komponen induk untuk mengkonsumsi data tersebut. Note: Slots are supported only with vue-native-helper version 0.0.9 and above. Vue Native just like Vue implements a content distribution API that's modeled after the current Web Components spec draft, using the slot element to serve as distribution outlets for content.
This page assumes you've already read the Components Basics. Read that first if you are new to components.
Slot Content
Vue implements a content distribution API that's modeled after the current Web Components spec draft, using the element to serve as distribution outlets for content.
This allows you to compose components like this:
Then in the template for , you might have:
When the component renders, the element will be replaced by 'Your Profile'. Slots can contain any template code, including HTML:
Or even other components:
If did not contain a element, any content passed to it would simply be discarded.
Named Slots
There are times when it's useful to have multiple slots. For example, in a hypothetical base-layout component with the following template:
For these cases, the element has a special attribute, name, which can be used to define additional slots:
To provide content to named slots, we can use the slot attribute on a element in the parent:
Or, the slot attribute can also be used directly on a normal element:
There can still be one unnamed slot, which is the default slot that serves as a catch-all outlet for any unmatched content. In both examples above, the rendered HTML would be:
Default Slot Content
There are cases when it's useful to provide a slot with default content. For example, a component might want the content of the button to be 'Submit' by default, but also allow users to override with 'Save', 'Upload', or anything else.
To achieve this, specify the default content in between the tags.
If the slot is provided content by the parent, it will replace the default content.
Compilation Scope
When you want to use data inside a slot, such as in:
That slot has access to the same instance properties (i.e. the same 'scope') as the rest of the template. The slot does not have access to ‘s scope. For example, trying to access url would not work. As a rule, remember that:
Everything in the parent template is compiled in parent scope; everything in the child template is compiled in the child scope.
Scoped Slots
New in 2.1.0+
Sometimes you'll want to provide a component with a reusable slot that can access data from the child component. For example, a simple component may contain the following in its template:
But in some parts of our app, we want the individual todo items to render something different than just the todo.text. This is where scoped slots come in.
To make the feature possible, all we have to do is wrap the todo item content in a element, then pass the slot any data relevant to its context: in this case, the todo object:
Now when we use the component, we can optionally define an alternative for todo items, but with access to data from the child via the slot-scope attribute:
In 2.5.0+, slot-scope is no longer limited to the element, but can instead be used on any element or component in the slot.
Destructuring slot-scope
Vuejs Slots Vs Props For Real
The value of slot-scope can actually accept any valid JavaScript expression that can appear in the argument position of a function definition. This means in supported environments (single-file components or modern browsers) you can also use ES2015 destructuring in the expression, like so:

This is a great way to make scoped slots a little cleaner.
