How to listen for click events that are outside of a component

Using the life-cycle methods add and remove event listeners to the document.

React.createClass({
    handleClick: function (e) {
        if (this.getDOMNode().contains(e.target)) {
            return;
        }
    },

    componentWillMount: function () {
        document.addEventListener('click', this.handleClick, false);
    },

    componentWillUnmount: function () {
        document.removeEventListener('click', this.handleClick, false);
    }
});
