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#


ValueLabelInputLabelHelp textDescription or error message

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:

NameTypeDescription
inputPropsTextFieldInputProps<TextFieldIntrinsicElements>Props for the input element.
labelPropsLabelHTMLAttributes<HTMLLabelElement>Props for the text field's visible label element, if any.
descriptionPropsHTMLAttributes<HTMLElement>Props for the text field's description element, if any.
errorMessagePropsHTMLAttributes<HTMLElement>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/textfield';

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>

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.
