Simple jQuery question
<p>I'm trying to do a tutorial.  I did one tutorial and things were great. Moving onto another and I can't get it to work.  I'm only posting because I just started this tutorial and things aren't working.  When 'Hello World' doesn't work I get frustrated.  Anyway, here is my HTML. Nothing special here.  I'm expecting a Hello World alert on page load, but I get nothing.</p>

<pre><code>&lt;html&gt;                                                                  
&lt;head&gt;                                                                  
    &lt;script type="text/javascript" src="jquery.js"&gt;&lt;/script&gt;          
    &lt;script type="text/javascript"&gt;  

        $(document).ready(function() {
    alert("Hello World");
    });

    &lt;/script&gt;  

&lt;/head&gt;                                                                 
&lt;body&gt;                                                                  
    &lt;h2&gt;My jQuery Test page&lt;/h2&gt;
    &lt;a href="http://www.google.com"&gt;Google&lt;/a&gt;
&lt;br&gt;                                      
    &lt;a href="http://www.yahoo.com"&gt;Yahoo&lt;/a&gt;
&lt;/body&gt;                                                                 
</code></pre>

<p></p>

<p>The original code was more complex, but it won't work either.</p>

<pre><code>$(document).ready(function() {
   $("a").click(function() {
     alert("Hello world!");
   });
 });
</code></pre>
