Checking if jquery is loaded using Javascript
<p>I am attempting to check if my Jquery Library is loaded onto my html page.  I am checking to see if it works, but something is not right.  Here is what I have.</p>

<pre><code>    &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
    &lt;head&gt;
    &lt;script type="text/javascript" src="/query-1.6.3.min.js"&gt;&lt;/script&gt;
    &lt;script type="text/javascript"&gt;
    $(document).Ready(function(){
    if (jQuery) {  
     // jQuery is loaded  
    alert("Yeah!");
    } else {
    // jQuery is not loaded
    alert("Doesn't Work");
        }
    });
</code></pre>
