Javascript loaded check through jquery getscript
<p>I want to load a Javascript file on the click event instead of loading at the page load event, for performance reasons.
Is there anyway to know that particular if javascript is already loaded?</p>

<p>Right now I am maintaining a global variable to check the 'loaded' event</p>

<pre><code>var javascriptLoaded=false

if (!javascriptLoaded)
        $.getScript('/scripts/test.js', function() {
            javascriptLoaded = true;
            setTimeout(function() {
            callSomeFunctionhere(); 
            }, 1000);                     
        });
</code></pre>

<p>Is there any better way of doing this?</p>
