jQuery Question

how to implement j-query plug in?

enter code here
I can't manage to successfully link jQuery to my html. I have made the most simple jQuery code possible just so I know it's right, and I've tried everything I can think of - searching hasn't been helpful..

my html file

<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<link rel="stylesheet" type="css/text" href="test.css"/>
<script type="text/javascript" src="test.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
</head>
<body>
<div id="orange"></div>
</body>
</html>

Answer

first of all you need to add a jquery library

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>

second: check your jquery working or not like

<script>
	$(function(fn){
		alert('Wow its workig');
	});
</script>
