# anchor-has-content
|
||
|
|
|
||
|
|
Enforce that anchors have content and that the content is accessible to screen readers. Accessible means that it is not hidden using the `aria-hidden` prop. Refer to the references to learn about why this is important.
|
||
|
|
|
||
|
|
## Rule details
|
||
|
|
|
||
|
|
This rule takes one optional object argument of type object:
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"rules": {
|
||
|
|
"jsx-a11y/anchor-has-content": [ 2, {
|
||
|
|
"components": [ "Anchor" ],
|
||
|
|
}],
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
For the `components` option, these strings determine which JSX elements (**always including** `<a>`) should be checked for having content. This is a good use case when you have a wrapper component that simply renders an `a` element (like in React):
|
||
|
|
|
||
|
|
```js
|
||
|
|
// Anchor.js
|
||
|
|
const Anchor = props => {
|
||
|
|
return (
|
||
|
|
<a {...props}>{ props.children }</a>
|
||
|
|
);
|
||
|
|
}
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
// CreateAccount.js (for example)
|
||
|
|
...
|
||
|
|
return (
|
||
|
|
<Anchor>Create Account</Anchor>
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
### Succeed
|
||
|
|
```jsx
|
||
|
|
<a>Anchor Content!</a>
|
||
|
|
<a><TextWrapper /><a>
|
||
|
|
<a dangerouslySetInnerHTML={{ __html: 'foo' }} />
|
||
|
|
```
|
||
|
|
|
||
|
|
### Fail
|
||
|
|
```jsx
|
||
|
|
<a />
|
||
|
|
<a><TextWrapper aria-hidden /></a>
|
||
|
|
```
|
