I am completely new to jquery and javascript. I am trying to complete a basic alert action using jquery, but it doesn't seem to work. I want an alert box to pop on loading the webpage.

I download jquery library 1.7.2 from the jquery website. When downloading my computer (running window 7) brings up a messages stating "the publsiher can not be verified" but yet the js file appears in my downloads folder (I am unable to open js file).

I have written the follow code into notepad and saved it as a html.....

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
<html xmlns="http://www.w3.org/1999/xhtml">
<title>jquery test</title>

<script type="text/javascript" src="jquery-1.7.2.min.js"></script>

<script type="text/javascript">

$(document).ready(function() {
alert("Jquery test 1-2-3");



<p>This is the jquery alert</p>


The webpage displays fine in IE, firefox etc... but the jquery action isn't working. Is the markup wrong?

I also tried the google CDN link but still no joy.

Any advise apprecited and thanks in advance
