Client

<div id="products">
<div style="float:right; width:350px; border:1px solid #ccc; padding:1em;">
<strong>Server response:</strong>
<ul id="response">
</ul>
</div>
<ul>
<li><h4>Product X (id: 312)</h4>
RateIt: <div data-productid="312" class="rateit"></div>
</li>
<li><h4>Product Y (id: 423)</h4>
RateIt: <div data-productid="423" class="rateit"></div></li>
<li><h4>Product Z (id: 653)</h4>
RateIt: <div data-productid="653" class="rateit"></div>
</li>
</ul>
</div>
<script type ="text/javascript">
//we bind only to the rateit controls within the products div
$('#products .rateit').bind('rated reset', function (e) {
var ri = $(this);
//if the use pressed reset, it will get value: 0 (to be compatible with the HTML range control), we could check if e.type == 'reset', and then set the value to  null .
var value = ri.rateit('value');
var productID = ri.data('productid'); // if the product id was in some hidden field: ri.closest('li').find('input[name="productid"]').val()
//maybe we want to disable voting?
ri.rateit('readonly', true);
$.ajax({
url: 'rateit.aspx', //your server side script
data: { id: productID, value: value }, //our data
type: 'POST',
success: function (data) {
$('#response').append('<li>' + data + '</li>');
},
error: function (jxhr, msg, err) {
$('#response').append('<li style="color:red">' + msg + '</li>');
}
});
});
</script>

<%@ Page Language="C#" %>
<%
//Get value
float value = float.Parse(Request.Form["value"]);
int productID = int.Parse(Request.Form["id"]);
Response.Write(string.Format("You voted {0} on product: {1}.<br/>Time on server: {2}", value, productID, DateTime.Now.ToString()));
%>

Resizing

<div class="rateit" id="rateit12"></div>
<p>Pick a size: 
<select id="size_12">
<option data-class="" data-size="16" selected>normal</option>
<option data-class="bigstars" data-size="32">big</option>
</select>
</p>
<script type="text/javascript">
$('#size_12').change(function () {
var option = $(this.options[this.selectedIndex]);
$('#rateit12').removeClass('bigstars') //remove old class
.addClass(option.data('class'))  //add new class
.rateit('starwidth', option.data('size')) //change width
.rateit('starheight', option.data('size')); //change height
});
</script>  

Confirmation before rating or resetting

<div class="rateit" id="rateit3"></div>
<script type="text/javascript">
$('#rateit13').on('beforerated', function (e, value) {
if (!confirm('Are you sure you want to rate this item: ' +  value + ' stars?')) {
e.preventDefault();
}
});
$('#rateit13').on('beforereset', function (e) {
if (!confirm('Are you sure you want to reset the rating?')) {
