Basic JavaScript alert not showing

Question

I've got an aspx masterpage and want to include Google's jQuery script. However, to test it's working, I've got the below code in the head of my masterpage. However, none of the content pages display the alert. What am I missing?

 <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" />

 <script type="text/javascript">
   $(document).ready(function() {                
     alert("Test Alert");                
   });
 </script>

Answer 1

<script> tags are not self-closing.

Replace

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" />

with

 <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
