Provides the behavior and accessibility implementation for a link component. A link allows a user to navigate to another page or resource within a web page or application.

API#
useLink(
(props: AriaLinkOptions,
, ref: RefObject<FocusableElement
| | null>
)): LinkAria
Features#
Links can be created in HTML with the <a>
element with an href
attribute. However, if the link does not have an href, and is
handled client side with JavaScript instead, it will not be exposed to assistive technology properly.
useLink
helps achieve accessible links with either native HTML elements or custom element types.
- Support for mouse, touch, and keyboard interactions
- Support for navigation links via
<a>
elements or custom element types via ARIA - Support for disabled links
Anatomy#
A link consists of a pressable area usually containing a textual label or an icon that users can click or tap to navigate to another page or resource. In addition, keyboard users may activate links using the Enter key.
useLink
returns props to be spread onto the link element:
Name | Type | Description |
linkProps | DOMAttributes | Props for the link element. |
isPressed | boolean | Whether the link is currently pressed. |
If a visual label is not provided (e.g. an icon or image only link), then an aria-label
or
aria-labelledby
prop must be passed to identify the link to assistive technology.
Example#
This example shows a basic link using a native <a>
element.
import {useLink} from 'react-aria';
function Link(props) {
let ref = React.useRef(null);
let { linkProps } = useLink(props, ref);
return (
<a
{...linkProps}
ref={ref}
style={{ color: 'var(--blue)' }}
>
{props.children}
</a>
);
}
<Link href="https://adobe.com" target="_blank">Adobe</Link>
import {useLink} from 'react-aria';
function Link(props) {
let ref = React.useRef(null);
let { linkProps } = useLink(props, ref);
return (
<a
{...linkProps}
ref={ref}
style={{ color: 'var(--blue)' }}
>
{props.children}
</a>
);
}
<Link href="https://adobe.com" target="_blank">
Adobe
</Link>
import {useLink} from 'react-aria';
function Link(props) {
let ref = React.useRef(
null
);
let { linkProps } =
useLink(props, ref);
return (
<a
{...linkProps}
ref={ref}
style={{
color:
'var(--blue)'
}}
>
{props.children}
</a>
);
}
<Link
href="https://adobe.com"
target="_blank"
>
Adobe
</Link>
Client handled links#
This example shows a client handled link using press events. It sets elementType
to span
so that useLink
returns the proper ARIA attributes to expose the element as a link to
assistive technology.
In addition, this example shows usage of the isPressed
value returned by useLink
to properly
style the links's active state. You could use the CSS :active
pseudo class for this, but isPressed
properly handles when the user drags their pointer off of the link, along with keyboard support and better
touch screen support.
function Link(props) {
let ref = React.useRef(null);
let { linkProps, isPressed } = useLink(
{ ...props, elementType: 'span' },
ref
);
return (
<span
{...linkProps}
ref={ref}
style={{
color: isPressed
? 'var(--blue)'
: 'var(--spectrum-global-color-blue-700)',
textDecoration: 'underline',
cursor: 'pointer'
}}
>
{props.children}
</span>
);
}
<Link onPress={() => alert('Pressed link')}>Adobe</Link>
function Link(props) {
let ref = React.useRef(null);
let { linkProps, isPressed } = useLink(
{ ...props, elementType: 'span' },
ref
);
return (
<span
{...linkProps}
ref={ref}
style={{
color: isPressed
? 'var(--blue)'
: 'var(--spectrum-global-color-blue-700)',
textDecoration: 'underline',
cursor: 'pointer'
}}
>
{props.children}
</span>
);
}
<Link onPress={() => alert('Pressed link')}>Adobe</Link>
function Link(props) {
let ref = React.useRef(
null
);
let {
linkProps,
isPressed
} = useLink({
...props,
elementType: 'span'
}, ref);
return (
<span
{...linkProps}
ref={ref}
style={{
color: isPressed
? 'var(--blue)'
: 'var(--spectrum-global-color-blue-700)',
textDecoration:
'underline',
cursor: 'pointer'
}}
>
{props.children}
</span>
);
}
<Link
onPress={() =>
alert(
'Pressed link'
)}
>
Adobe
</Link>
Disabled links#
A link can be disabled by passing the isDisabled
property. This will work with both native
link elements as well as client handled links. Native navigation will be disabled, and the onPress
event will not be fired. The link will be exposed as disabled to assistive technology with ARIA.
function Link(props) {
let ref = React.useRef(null);
let { linkProps } = useLink(props, ref);
return (
<a
{...linkProps}
ref={ref}
style={{
color: props.isDisabled ? 'var(--gray)' : 'var(--blue)',
cursor: props.isDisabled ? 'default' : 'pointer'
}}
>
{props.children}
</a>
);
}
<Link href="https://adobe.com" target="_blank" isDisabled>Disabled link</Link>
function Link(props) {
let ref = React.useRef(null);
let { linkProps } = useLink(props, ref);
return (
<a
{...linkProps}
ref={ref}
style={{
color: props.isDisabled
? 'var(--gray)'
: 'var(--blue)',
cursor: props.isDisabled ? 'default' : 'pointer'
}}
>
{props.children}
</a>
);
}
<Link href="https://adobe.com" target="_blank" isDisabled>
Disabled link
</Link>
function Link(props) {
let ref = React.useRef(
null
);
let { linkProps } =
useLink(props, ref);
return (
<a
{...linkProps}
ref={ref}
style={{
color:
props
.isDisabled
? 'var(--gray)'
: 'var(--blue)',
cursor:
props
.isDisabled
? 'default'
: 'pointer'
}}
>
{props.children}
</a>
);
}
