How can I handle an event to open a window in react js?
You are on the right way!
Is it something you need? I prepared the example: click here
var Example = React.createClass({ fbShare: function() { window.open('http://www.facebook.com/sharer.php?s=100&p[title]=Fb Share&p[summary]=Facebook share popup&p[url]=javascript:fbShare("http://jsfiddle.net/stichoza/EYxTJ/")&p[images][0]="http://goo.gl/dS52U"', 'sharer', 'toolbar=0,status=0,width=548,height=325'); }, render: function() { return (<div> <img src="http://pasadenainstitute.com/fb-shareTransp122x42.png" onClick={this.fbShare} /> </div>); }});ReactDOM.render( <Example />, document.getElementById('container'));
