This article mainly introduces "how to deliver HTML content through the components of Vue slot". In daily operation, I believe many people have doubts about how to transmit HTML content through the components of Vue slot. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the questions of "how to transmit HTML content through the components of Vue slot". Next, please follow the editor to study!

What is a Vue slot?

Vue slots are Vue template elements created by the Vue team to provide a platform for template content distribution. It is an implementation of content distribution API inspired by the draft Web Components specification. Using Vue slots, you can pass or distribute HTML code across components in a project.

Content distribution is important for many reasons, some of which are related to structure. Using Vue slots, you can build the HTML interface (like TypeScript), which you can then use as a guide for building components through template injection. It is an extensible and efficient solution for passing template code from one component to another.

Content positioning is another important use case for Vue slots. You can create just one template and then use another component or parent component to arrange the template, just as you want it to appear in the user interface.

If you know Vue slots, you may want to know if props and slots do the same thing. Then, the core idea of these tools or platforms is to encourage the reusability and efficiency of resources. With this in mind, slots and props are similar.

Props handle passing data objects from component to component, but slots handle delivery template (HTML) content rather than components. However, the slots in the range are like props; this will be clearly explained in this tutorial.

Vue slot syntax

For slots, your subcomponents act as the interface or structure of how you want to arrange the content. It looks like this:

The parent component (where the HTML content of the child component is to be injected) may be as follows:

Hello World!

This combination returns the user interface as follows:

Hello World!

Notice how its own slot serves as a guide to where and how content is injected-this is the central idea.

Named slot

Vue allows components to have multiple slots, which means you can have any number of slots. To test this, copy this new block of code into your file: test.vue

Export default {name:'Test'}

If you run the application, you can see that hello world prints three times. So if you want to add more content-such as headings, paragraphs with text, and then unordered lists-Vue allows us to name ranges so that it can identify specific ranges to display. The slots in the named file will look like this: test.vue

Export default {name:'Test'}

Now you must also mark the HTML element based on the name of the slot in which you want to display them. Copy it to the template section of the file: app.vue

Hello world

I am the paragraph text.

Hello, I am a list item

V-slots syntax

When Vue version 2.6 was released, it provided a better syntax for referencing slot names in a subcomponent named v-slot, which meant replacing the initial slot syntax. So, instead of the parent component template for slots like this:

Hello world!

From version 3.0 (which should be released by the end of the year), it now looks like this:

Hello world!

Note that the slight change from the string is that in addition to slot pairs, there is another major change: v-slots can only be defined in templates, not any HTML elements. This is a big change because it questions the availability of naming slots, but at the time of this writing, slots are still part of the documentation. V-slot

Scoped slot

Imagine a scenario where Vue slots can also access data objects in child components from the parent component-a slot with props capabilities. To illustrate this, continue to create data objects in the subcomponents by copying the following code block into a file: test.vue

Export default {name:'Test'

Data () {

Return {team: "FC Barcelona"}

}

}

Just like a normal props, the v-bind instruction is used to bind the team in the data to the prop reference in the parent component. Open the file and copy the following code block to the template section: app.vue

Hello {{team}}

If you run the application, you will see that the data object has been successfully passed to the parent component.
