React Click Outside
Enhance a React component with a Higher Order Component that provides click outside detection.
Note: React 0.14 required for version >= 2.x. This assumes react and
react-dom is installed in your project. Continue using version 1.x for React
0.13 support.
Note: Use version >= 2.3.0 to get rid of React.createClass
warnings in React 15.5.
Usage
Installation:
npm install react-click-outside
Some component that you wish to enhance with click outside detection:
const createReactClass = require('create-react-class');
const enhanceWithClickOutside = require('react-click-outside');
const React = require('react');
const Dropdown = createReactClass({
getInitialState() {
return {
isOpened: false,
};
},
handleClickOutside() {
this.toggle();
},
toggle() {
this.setState({ isOpened: !this.state.isOpened });
},
render() {
...
},
});
module.exports = enhanceWithClickOutside(Dropdown);
Note: There will be no error thrown if handleClickOutside is not
implemented.
wrappedRef prop
Use the wrappedRef prop to get access to the wrapped component instance. For
example:
// Inside a component's render method
<Dropdown
wrappedRef={instance => { this.toggle = instance.toggle; }}
/>
// Now you can call toggle externally
this.toggle();
Details
The enhanceWithClickOutside function wraps the provided component in another
component that registers a click handler on document for the event capturing
phase. Using the event capturing phase prevents elements with a click handler
that calls stopPropagation from cancelling the click event that would
eventually trigger the component's handleClickOutside function.
Why not a mixin?
There are some mixins that provide click outside detection functionality, but
they prevent the component from implementing the componentDidMount and
componentWillUnmount life cycle hooks. I recommend not using a mixin for this
case.
Limitations
- IE9+ due to the usage of the event capturing phase.
Not working on iOS?
If the handleClickOutside handler is not firing on iOS, try adding the
cursor: pointer css style to the <body> element. There are many ways to
achieve this, here is just one example:
if ('ontouchstart' in document.documentElement) {
document.body.style.cursor = 'pointer';
}
If your app already has a way for mobile detection (e.g. Modernizr), you may want to use that instead.
See issue #4 for a discussion.
