🚫 This rule is disabled in the following configs: ☑️ recommended
, 🔒 strict
.
Enforce that a control (an interactive element) has a text label.
There are two supported ways to supply a control with a text label:
- Provide text content inside the element.
- Use the
aria-label
attribute on the element, with a text value. - Use the
aria-labelledby
attribute on the element, and point the IDREF value to an element with an accessible label. - Alternatively, with an
img
tag, you may use thealt
attribute to supply a text description of the image.
The rule is permissive in the sense that it will assume that expressions will eventually provide a label. So an element like this will pass.
<button type="button">{maybeSomethingThatContainsALabel}</button>
Provide text content in the button
element.
<button type="button">Save</button>
Use the aria-label
attribute and provide the text label as the value.
<button type="button" aria-label="Save" class="icon-save" />
Case: The label for my element is already located on the page and I don't want to repeat the text in my source code.
Use the aria-labelledby
attribute and point the IDREF value to an element with an accessible label.
<div id="js_1">Comment</div>
<textarea aria-labelledby="js_1"></textarea>
Case: My label and input components are custom components, but I still want to require that they have an accessible text label.
You can configure the rule to be aware of your custom components. Refer to the Rule Details below.
<CustomInput label="Surname" type="text" value={value} />

labelAttributes
is a list of attributes to check on the control component and its children for a label. Use this if you have a custom component that uses a string passed on a prop to render an HTMLlabel
, for example.controlComponents
is a list of custom React Components names that will render down to an interactive element.ignoreElements
is an array of elements that should not be considered control (interactive) elements and therefore they do not require a text label.ignoreRoles
is an array of ARIA roles that should not be considered control (interactive) roles and therefore they do not require a text label.depth
(default 2, max 25) is an integer that determines how deep within aJSXElement
the rule should look for text content or an element with a label to determine if the interactive element will have an accessible label.
