React js how to inject javascript in jsx object
<p>I don't want to display <code>"no file selected"</code> on input file and replacing with another button.</p>

<pre><code>var form = React.createClass({
   render : function(){
        var fileStyle = { display : none };
        return (
         &lt;form&gt;
            &lt;input id="file" type="file" style={fileStyle}&gt;
            &lt;button onClick={ /* how to perform click on file*/ }&gt; click to add image&lt;/button&gt;
         &lt;/form&gt;
        );
    }
});
</code></pre>

<p>I want when I click button then input file is perform click.</p>

<p>How to accomplish this within React js?</p>
