Is there a way to detect whether an external javascript file is fully loaded?
<p>I have a web form that uses <strong>reCAPTCHA</strong> to filter out robots. The form has a <code>&lt;script&gt;</code> tag that loads the captcha challenge in an <code>&lt;iframe&gt;</code>. If this script fails to load, then the captcha challenge would not appear and no one would be able to send a post.</p>

<p>Is there any way that I can detect whether the script is loaded so that I can turn off this feature from my side?</p>
