Installation
# npm

# yarn
yarn add click-away
Usage
Suppose you're working on a Modal
component that renders a dialog box, and you wish to close the modal if the user clicks away.
import React from 'react';
// Not shown: CSS rules for `.modal`, `.modal-open`, `.modal-closed`
export default function Modal({isOpen, onClose, children}) {
const className = `modal modal-${isOpen ? 'open' : 'closed'}`;
return (
<div className={className}>
{children}
</div>
);
}
Adding behavior to close the modal is as easy as passing click-away
as a ref
, with a reference to the callback you wish to use:
import React from 'react';
import callOnClickAway from 'click-away';
export default function Modal({isOpen, onClose, children}) {
const className = `modal modal-${isOpen ? 'open' : 'closed'}`;
return (
<div className={className} ref={callOnClickAway(onClose)}>
{children}
</div>
);
}
Documentation
callOnClickAway(callback)
Returns a function you can pass as a React or Preact ref
, which calls the given callback when the user clicks anywhere outside the rendered element.
For instance, if you render this:
<div ref={callOnClickAway(handler)}>Hello!</div>
then the handler
function will be called any time the use clicks outside the div.
Caveats
Using component style libraries with click-away
If you're using emotion
, styled-components
, glamorous
, or similar, keep in mind you need to pass the callback to innerRef
instead of ref
.
