What tags are used to define dynamic components in vue

Define the tags of dynamic components in Vue.js

In Vue.js, you can use<component> tag to define dynamic components. This tag allows you to dynamically render a component based on its name contained in the Vue instance data.

Using <component> Tags

##<component> The basic syntax of tags is as follows:

<code class="html"><component :is="componentName"></component></code>
Among them,

componentName is a Vue instance data property, which contains the name of the component to be rendered.

Example

The following example shows how to dynamically render a component using the

<component> tag:

<code class="javascript">// Vue 实例代码
data() {
  return {
    currentComponent: 'ComponentA',
  };
},</code>
<code class="html"><!-- 模板代码 -->
<template>
  <div>
    <component :is="currentComponent"></component>
  </div>
</template></code>
In this case In this case, the

<component> tag will render the ComponentA component based on the value of the currentComponent data property.

Function

componentName can be a string, an object, or a function. It can also be a variable declared in a data attribute:

  • String: Renders the component with the specified name.
  • Object: Renders a component options object.
  • Function: Renders a function that returns a component options object.

Notes

    Make sure
  • componentName always points to a valid component.
  • <component> Tags must contain a single root element.
  • Dynamic components cannot use template
