Enforce onmouseover/onmouseout are accompanied by onfocus/onblur. Coding for the keyboard is important for users with physical disabilities who cannot use a mouse, AT compatibility, and screenreader users.
|
||
|
|
|
||
|
|
## Rule details
|
||
|
|
|
||
|
|
This rule takes no arguments.
|
||
|
|
|
||
|
|
### Succeed
|
||
|
|
```jsx
|
||
|
|
<div onMouseOver={ () => void 0 } onFocus={ () => void 0 } />
|
||
|
|
<div onMouseOut={ () => void 0 } onBlur={ () => void 0 } />
|
||
|
|
<div onMouseOver={ () => void 0 } onFocus={ () => void 0 } {...otherProps} />
|
||
|
|
<div onMouseOut={ () => void 0 } onBlur={ () => void 0 } {...otherProps} />
|
||
|
|
```
|
||
|
|
|
||
|
|
### Fail
|
||
|
|
In example 3 and 4 below, even if otherProps contains onBlur and/or onFocus, this rule will still fail. Props should be passed down explicitly for rule to pass.
|
||
|
|
|
||
|
|
```jsx
|
||
|
|
<div onMouseOver={ () => void 0 } />
|
||
|
|
<div onMouseOut={ () => void 0 } />
|
||
|
|
<div onMouseOver={ () => void 0 } {...otherProps} />
|
||
|
|
<div onMouseOut={ () => void 0 } {...otherProps} />
|
||
|
|
```
