Can someone see where I'm going wrong with this form validation? I was using an example I found online and it does not work for me.
I want to validated the input fields with the jquery before passing it on to the server side script. It supposed to print error message next to the field where the user is missing an input.
Here's the code:

Here's the code the original code that I got from a website somewhere and it works. But I can't seem to use the example in my code.
<html>
<head>
<title>Simple Form Validation</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="http://dev.jquery.com/view/trunk/plugins/validate/jquery.validate.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#form2").validate({
rules: {
name: "required",// simple rule, converted to {required:true}
email: {// compound rule
required: true,
email: true
},
url: {
url: true
},
comment: {
required: true
}
},
messages: {
comment: "Please enter a comment."
}
});
});
</script>
</head>
<body>
<form id="form2" method="post" action=""><br />
Name * <input type="text" name="name" /> <br />
E-Mail *<input type="text" name="email" /> <br />
URL <input type="text" name="url" /> <br />
Your comment * <textarea name="comment" ></textarea> <br />
<input class="submit" type="submit" value="Submit">
</form>
</body>
</html>
Update: Thanks to @Usman it's now working. One more question though, is it possible to change the default error message instead of the 'This field is required' ?
Thanks
Remove non-existing fields from validation rule, url etc. I have removed these and its working. Working http://jsfiddle.net/xyRRU/ , check the code below:
