Vue $attrs Object


Example

Using the $attrs object to direct the id fallthrough attribute to the <p> tag.

<template>
  <h3>Tigers</h3>
  <img src="/img_tiger_small.jpg" alt="tiger">
  <p v-bind="$attrs">Tigers eat meat and not plants, so they are called carnivores.</p>
</template>
Run Example »

See more examples below.


Definition and Usage

The $attrs object represents the fallthrough attributes and the event listeners set on the component tag.

We use v-bind="$attrs" on a root element when we want that element to inherit the fallthrough attributes and event listeners set on the component tag.

The $attrs object is read only.

Fallthrough Attributes are attributes (not props) set on the component tag, that falls through to the root element of the component. If there are more than one root element in the component, we use the $attrs object to specify which element that should inherit the fallthrough attributes. Learn more about fallthrough attributes in the tutorial.
