I have tested the following code on w3schools.com; however, when I tried it on my local machine it does not work. I have a feeling that the cause is that I do not have the file jquery.js. I was thinking that it was only part of the jquery script declaration and no more. What is written in jquery.js? Is there an alternative file I can include?

<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
  $("button").click(function(){
    $(this).hide();
  });
});
</script>
</head>

<body>
<button>Click me</button>
</body>
</html>

    You can either change this line 

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

    to

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

    Which will load the jQuery library from google CDN(Content Delivery Network). There are several other CDN, check the list here http://docs.jquery.com/Downloading_jQuery#CDN_Hosted_jQuery

    Or

    Load https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js in browser and save the file as jquery.js in the directory where your above file is and your code will work fine.
