Jquery library issues for absolute beginner

JavaScript
1

Hi

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”
“http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”>
<html xmlns=“http://www.w3.org/1999/xhtml”>
<head>
<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”);
});
</script>
</head>

<body>

<h2>Test</h2>

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

</body>
</html>

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

I used the code you posted and substituted in the google CDN link, and everything worked exactly as I expected, alert and all. So either the code you posted isn’t the code you’re actually running… or something is very messed up on your computer. I’m not sure I can be any more help than that at this point.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head>
<title>jquery test</title>

<script type="text/javascript" src="[COLOR="#FF0000"]https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js[/COLOR]"></script>

<script type="text/javascript">

$(document).ready(function() {
alert("Jquery test 1-2-3");
});
</script>
</head>

<body>

<h2>Test</h2>

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

</body>
</html>
