    text
    copied!<p>I am creating a page which can play a video file with alternate plug-ins based on users selection. The URL encodes which video should be played.</p> <p>The page is retrieved from a PHP server script. The user selects the plug-in by clicking on some AJAX links. Each link retrieves from server the required plug-in by doing an AJAX request with a Javascript function. This function must take as a parameter the video ID. On the client side I am using jQuery Javascript framework.</p> <p>I would like to know which is the best practice for doing this as a design pattern. I am thinking at several alternatives:</p> <ol> <li>use <code>onclick</code> HTML attribute for the AJAX links to call the functions that retrieve content from server</li> <li>use jQuery <code>$(#element).click()</code> to map the Javascript function which retrieves content.</li> </ol> <p>If I use the first alternative a can easily pass the video ID to the Javascript function:</p> <pre><code>&lt;a id="X" href="#" onclick="retrieveXPlugin('&lt;?php echo $id ?&gt;')"&gt;X Plugin&lt;/a&gt; </code></pre> <p>but the view code is mashed with events code, which is not a good practice.</p> <p>The second alternative looks better, but I must bind the click event in the same PHP file like this:</p> <pre><code>&lt;script type="text/javascript"&gt; $(document).ready(function() { $('#X').click(function() { retrieveXPlugin('&lt;?php echo $id ?&gt;'); }); } &lt;/script&gt; </code></pre> <p>As I figure out I cannot include the above code in a separate .js file because I need the server side PHP variable <code>$id</code>. The only way to do this would be to use global Javascript variables which doesn't look so good.</p> <p>So, which is the best practice to organize view and events in this example and in any other? I am waiting for your suggestions.</p>
