How do i open a javascript file, when someone clicks on a button?
<p>I have a website and I have this javascript code im going to place in the header below</p>

<pre><code>&lt;!-- GATEWAY --&gt;
&lt;script type="text/javascript" src="http://www.al.com/al.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript"&gt; 
    al.check('f6687144358efd6746bc25f7c145f760'); 
&lt;/script&gt;
</code></pre>

<p>Now I want to open that javascript when someone clicks on a button on my website. ( IMG HTML BUTTON )</p>
