Vue3 inheritAttrs Attribute
In Vue3, `inheritAttrs` is a component option that determines whether non-prop attributes passed from a parent component to a child component (i.e., attributes not explicitly defined as props) should be inherited by the child component's root element.
By default, the value of `inheritAttrs` is `true`, which means all non-prop attributes passed from the parent component are automatically bound to the child component's root element. If you want to manually control the inheritance behavior of these attributes, you can set `inheritAttrs` to `false`.
How to Understand `inheritAttrs`?
Imagine you have a component `MyButton` that accepts a `label` as a prop, and you want the parent component to pass some additional attributes, such as `class` or `style`. By default, these extra attributes are directly bound to the root element of `MyButton` (usually a `
Example
// MyButton.vue
<template>
<button :class="$attrs.class">{{ label }}</button>
</template>
<script>
export default{
props:['label'],
inheritAttrs:true
}
</script>In this example, if the parent component passes a `class` attribute, it will be automatically bound to the `
The Purpose of `inheritAttrs: false`
If you do not want these non-prop attributes to be automatically bound to the root element, you can set `inheritAttrs` to `false`. This way, you can manually decide how these attributes should be handled.
Example
// MyButton.vue
<template>
<div>
<button>{{ label }}</button>
<span v-bind="$attrs">Additional Attributes</span>
</div>
</template>
