API#
useTextField<T extends TextFieldIntrinsicElements = DefaultElementType>(
(props: AriaTextFieldOptions<T>,
, ref: TextFieldRefObject<T>
)): TextFieldAria<T>
Features#
Text fields can be built with <input>
or <textarea>
and <label> elements,
but you must manually ensure that they are semantically connected via ids for accessibility.
useTextField
helps automate this, and handle other accessibility features while
allowing for custom styling.
- Built with a native
<input>
or<textarea>
element - Visual and ARIA labeling support
- Change, clipboard, composition, selection, and input event support
- Required and invalid states exposed to assistive technology via ARIA
- Support for description and error message help text linked to the input via ARIA
Anatomy#
Text fields consist of an input element and a label. useTextField
automatically manages
the relationship between the two elements using the for
attribute on the <label>
element
and the aria-labelledby
attribute on the <input>
element.
useTextField
also supports optional description and error message elements, which can be used
to provide more context about the field, and any validation messages. These are linked with the
input via the aria-describedby
attribute.
useTextField
returns props that you should spread onto the appropriate element:
Name | Type | Description |
inputProps | TextFieldInputProps<TextFieldIntrinsicElements> | Props for the input element. |
labelProps | DOMAttributes | Props for the text field's visible label element, if any. |
descriptionProps | DOMAttributes | Props for the text field's description element, if any. |
errorMessageProps | DOMAttributes | Props for the text field's error message element, if any. |
If there is no visual label, an aria-label
or aria-labelledby
prop must be passed instead
to identify the element to screen readers.
Example#
import {useTextField} from 'react-aria';
function TextField(props) {
let { label } = props;
let ref = React.useRef();
let { labelProps, inputProps, descriptionProps, errorMessageProps } =
useTextField(props, ref);
return (
<div style={{ display: 'flex', flexDirection: 'column', width: 200 }}>
<label {...labelProps}>{label}</label>
<input {...inputProps} ref={ref} />
{props.description && (
<div {...descriptionProps} style={{ fontSize: 12 }}>
{props.description}
</div>
)}
{props.errorMessage && (
<div {...errorMessageProps} style={{ color: 'red', fontSize: 12 }}>
{props.errorMessage}
</div>
)}
</div>
);
}
<TextField label="Email" />
import {useTextField} from 'react-aria';
function TextField(props) {
let { label } = props;
let ref = React.useRef();
let {
labelProps,
inputProps,
descriptionProps,
errorMessageProps
} = useTextField(props, ref);
return (
<div
style={{
display: 'flex',
flexDirection: 'column',
width: 200
}}
>
<label {...labelProps}>{label}</label>
<input {...inputProps} ref={ref} />
{props.description && (
<div {...descriptionProps} style={{ fontSize: 12 }}>
{props.description}
</div>
)}
{props.errorMessage && (
<div
{...errorMessageProps}
style={{ color: 'red', fontSize: 12 }}
>
{props.errorMessage}
</div>
)}
</div>
);
}
<TextField label="Email" />
import {useTextField} from 'react-aria';
function TextField(
props
) {
let { label } = props;
let ref = React
.useRef();
let {
labelProps,
inputProps,
descriptionProps,
errorMessageProps
} = useTextField(
props,
ref
);
return (
<div
style={{
display: 'flex',
flexDirection:
'column',
width: 200
}}
>
<label
{...labelProps}
>
{label}
</label>
<input
{...inputProps}
ref={ref}
/>
{props
.description && (
<div
{...descriptionProps}
style={{
fontSize: 12
}}
>
{props
.description}
</div>
)}
{props
.errorMessage &&
(
<div
{...errorMessageProps}
style={{
color:
'red',
fontSize:
12
}}
>
{props
.errorMessage}
</div>
)}
</div>
);
}
<TextField label="Email" />
Text area#
useTextField
also supports multi-line text entry with the <textarea>
element via the inputElementType
prop.
import {useTextField} from 'react-aria';
function TextArea(props) {
let { label } = props;
let ref = React.useRef();
let { labelProps, inputProps } = useTextField({
...props,
inputElementType: 'textarea'
}, ref);
return (
<div style={{ display: 'flex', flexDirection: 'column', width: 200 }}>
<label {...labelProps}>{label}</label>
<textarea {...inputProps} ref={ref} />
</div>
);
}
<TextArea label="Description" />
import {useTextField} from 'react-aria';
function TextArea(props) {
let { label } = props;
let ref = React.useRef();
let { labelProps, inputProps } = useTextField({
...props,
inputElementType: 'textarea'
}, ref);
return (
<div
style={{
display: 'flex',
flexDirection: 'column',
width: 200
}}
>
<label {...labelProps}>{label}</label>
<textarea {...inputProps} ref={ref} />
</div>
);
}
<TextArea label="Description" />
import {useTextField} from 'react-aria';
function TextArea(
props
) {
let { label } = props;
let ref = React
.useRef();
let {
labelProps,
inputProps
} = useTextField({
...props,
inputElementType:
'textarea'
}, ref);
return (
<div
style={{
display: 'flex',
flexDirection:
'column',
width: 200
}}
>
<label
{...labelProps}
>
{label}
</label>
<textarea
{...inputProps}
ref={ref}
/>
</div>
);
}
<TextArea label="Description" />
Usage#
The following examples show how to use the TextField
component created in the above example.
Default value#
A TextField's value
is empty by default, but an initial, uncontrolled, value can be provided using the defaultValue
prop.
<TextField
label="Email"
defaultValue="me@email.com" />
<TextField
label="Email"
defaultValue="me@email.com" />
<TextField
label="Email"
defaultValue="me@email.com"
/>
Controlled value#
The value
prop can be used to make the value controlled. The onChange
event is fired when the user edits the text, and receives the new value.
function Example() {
let [text, setText] = React.useState();
return (
<>
<TextField label="Your text" onChange={setText} />
<p>Mirrored text: {text}</p>
</>
);
}
function Example() {
let [text, setText] = React.useState();
return (
<>
<TextField label="Your text" onChange={setText} />
<p>Mirrored text: {text}</p>
</>
);
}
function Example() {
let [text, setText] =
React.useState();
return (
<>
<TextField
label="Your text"
onChange={setText}
/>
<p>
Mirrored text:
{' '}
{text}
</p>
</>
);
}
Description#
The description
prop can be used to associate additional help text with a text field.
<TextField
label="Email"
description="Enter an email for us to contact you about your order."
/>
<TextField
label="Email"
description="Enter an email for us to contact you about your order."
/>
<TextField
label="Email"
description="Enter an email for us to contact you about your order."
/>
Error message#
The errorMessage
prop can be used to help the user fix a validation error. It should be combined with the validationState
prop to
semantically mark the input element as invalid for assistive technologies.
<TextField
label="Email"
validationState="invalid"
errorMessage="Please enter a valid email address." />
<TextField
label="Email"
validationState="invalid"
errorMessage="Please enter a valid email address." />
<TextField
label="Email"
validationState="invalid"
errorMessage="Please enter a valid email address."
/>
Disabled#
A TextField can be disabled using the isDisabled
prop.
<TextField label="Email" isDisabled />
<TextField label="Email" isDisabled />
<TextField
label="Email"
isDisabled
/>
Read only#
The isReadOnly
boolean prop makes the TextField's text content immutable. Unlike isDisabled
, the TextField remains focusable
and the contents can still be copied. See the MDN docs for more information.
<TextField label="Email" defaultValue="abc@adobe.com" isReadOnly />
<TextField
label="Email"
defaultValue="abc@adobe.com"
isReadOnly
/>
<TextField
label="Email"
defaultValue="abc@adobe.com"
isReadOnly
/>
Required#
A TextField can be marked as required using the isRequired
prop. This is exposed to assistive technologies by React Aria. It's your responsibility to add additional visual styling if needed.
<TextField label="Email" isRequired />
<TextField label="Email" isRequired />
<TextField
label="Email"
isRequired
/>
HTML forms#
TextField supports the name
prop for integration with HTML forms. In addition, attributes such as type
, pattern
, inputMode
, and others are passed through to the underlying <input>
element.
<TextField label="Email" name="email" type="email" />
<TextField label="Email" name="email" type="email" />
<TextField
label="Email"
name="email"
type="email"
/>
Internationalization#
RTL#
In right-to-left languages, text fields should be mirrored. The label should be right aligned, along with the text in the text field. Ensure that your CSS accounts for this.
