Simple CRUD with JQuery-2

The main screen is index.jsp . This screen has the new, save, delete,
next, prev and list buttons. The list button is not functional at
this moment. I will provide that in the near future.

<h1>The Simplest JQuery CRUD Application</h1>

<form name="theDetail" action="" method="get">
<input type="hidden" id="id" name="id"/><br />
First name: <input type="text" id ="name" name="name"/><br />
Last name : <input type="text" id="last" name="last"/><br />
Hobby : <input type="text" id="hobby" name="hobby"/><br />
<br />
<INPUT TYPE="button" id="New" VALUE="New">
<INPUT TYPE="button" id="Save" VALUE="Save">
<INPUT TYPE="button" id="Delete" VALUE="Delete">
<INPUT TYPE="button" id="Next" VALUE="Next">
<INPUT TYPE="button" id="Prev" VALUE="Prev">
<INPUT TYPE="button" id="List" VALUE="List">
</form>
</body>

Each button is linked to an event handler in the java script file
