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.

Usage

Installation:

npm install react-click-outside

Some component that you wish to enhance with click outside detection:

const enhanceWithClickOutside = require('react-click-outside');
const React = require('react');

const Dropdown = React.createClass({
  getInitialState() {
    return {
      isOpened: false,
    };
  },

  handleClickOutside() {
    this.setState({ isOpened: false });
  },

  render() {
    ...
  },
});

module.exports = enhanceWithClickOutside(Dropdown);

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.
